Introduction ----------------- - -This software is used to set up a Lora concentrator using a JSON configuration -file and then record all the packets received in a log file, indefinitely, until -the user stops the application. -No filtering is done and all packets that are Lora packets with the correct RF -parameters (frequency, datarate, bandwidth) should appear in the log. - -2. Dependencies ----------------- - -This program uses the Parson library (http://kgabis.github.com/parson/) by -Krzysztof Gabis for JSON parsing. -Many thanks to him for that very practical and well written library. - -This program is a typical example of Lora Gateway HAL usage for receiving -packets. - -Only high-level functions are used (the ones contained in loragw_hal) so there -is no hardware dependencies assuming the HAL is matched with the proper version -of the hardware. -Data structures of the received packets are accessed by name (ie. not at a -binary level) so new functionalities can be added to the API without affecting -that program at all. - -It was tested with v1.0.0 of the libloragw library, and should be compatible -with any later version of the library assuming the API is downward-compatible. - -3. Usage ---------- - -To stop the application, press Ctrl+C. - -The only optional parameter when launching the application is the log rotation -time (in seconds). - -The way the program takes configuration files into account is the following: - * if there is a debug_conf.json parse it, others are ignored - * if there is a global_conf.json parse it, look for the next file - * if there is a local_conf.json parse it -If some parameters are defined in both global and local configuration files, the -local definition overwrites the global definition. - -The global configuration file should be exactly the same throughout your -network, contain all global parameters (parameters for "sensor" radio channels) -and preferably default "safe" values for parameters that are specific for each -gateway (eg. specify a default MAC address). - -The local configuration file should contain parameters that are specific to each -gateway (eg. MAC address, frequency for backhaul radio channels). - -In each configuration file, the program looks for a JSON object named -"SX1301_conf" that should contain the parameters for the Lora concentrator board -(RF channels definition, modem parameters, etc) and another JSON object called -"gateway_conf" that should contain the gateway parameters (gateway MAC address, -IP address of the Lora MAC controller, network authentication parameters, etc). - -To learn more about the JSON configuration format, read the provided JSON files -and the API documentation. A dedicated document will be available later on. - -The received packets are put in a CSV file whose name include the MAC address of -the gateway in hexadecimal format and a UTC timestamp of log starting time in -ISO 8601 recommended compact format: -yyyymmddThhmmssZ (eg. 20131009T172345Z for October 9th, 2013 at 5:23:45PM UTC) - -To able continuous monitoring, the current log file is closed is closed and a -new one is opened every hour (by default, rotation interval is settable by the -user using -r command line option). -No packet is lost during that rotation of log file. -Every log file but the current one can then be modified, uploaded and/or deleted -without any consequence for the program execution. - -4.

Introduction ----------------- - -This software is used to send test packets with a Lora concentrator. The packets -contain little information, on no protocol (ie. MAC address) information but -can be used to assess the functionality of a gateway downlink using other -gateways as receivers. - -2. Dependencies ----------------- - -This program is a typical example of Lora Gateway HAL usage for sending packets. - -Only high-level functions are used (the ones contained in loragw_hal) so there -is no hardware dependencies assuming the HAL is matched with the proper version -of the hardware. -Data structures of the sent packets are accessed by name (ie. not at a -binary level) so new functionalities can be added to the API without affecting -that program at all. - -It was tested with v1.0.0 of the libloragw library, and should be compatible -with any later version of the library assuming the API is downward-compatible. - -3. Usage ---------- - -The application runs until the specified number of packets have been sent. -Press Ctrl+C to stop the application before that. - -Use the -f option followed by a real number (decimal point and scientific -'E notation' are OK) to specify the modulation central frequency. - -Use the -s option to specify the Spreading Factor of Lora modulation (values 7 -to 12 are valid). - -Use the -b option to set Lora modulation bandwidth in kHz (accepted values: 125, -250 or 500). - -Use the -p option to set the concentrator TX power in dBm. Not all values are -supported by hardware (typically 14 et 20 dBm are supported, other values might -not give expected power). Check with a RF power meter before connecting any -sensitive equipment. - -Use the -t option to specify the number of milliseconds of pause between -packets. Using zero will result in a quasi-continuous emission. - -Use the -x option to specify how many packets should be sent. - -Use the -i option to invert the Lora modulation polarity. - -The packets are 20 bytes long, and protected by the smallest supported ECC. - -The payload content is: -[T][E][S][T][packet counter MSB][packet counter LSB] followed by ASCII padding. -All Lora data is whitened, so the padding has no influence whatsoever on the -packet error rate. - -4.

Core library: libloragw +--------------------------- + +This directory contains the sources of the library to build a gateway based on +a Semtech LoRa multi-channel RF receiver (a.k.a. concentrator). +Once compiled all the code is contained in the libloragw.a file that will be +statically linked (ie. integrated in the final executable). + +The library must be configured by editing the library.cfg file to set target +chip, radio, SPI interface, etc. + +The library also comes with a bunch of basic tests programs that are used to +test the different sub-modules of the library. + +2. Helper programs +------------------- + +Those programs are included in the project to provide examples on how to use +the HAL library, and to help the system builder test different parts of it. + +### 2.1. util_band_survey ### + +This software is used to scan the RF band and measure background RSSI and some +measurement of interferer pattern. + +### 2.2. util_pkt_logger ### + +This software is used to set up a LoRa concentrator using a JSON configuration +file and then record all the packets received in a log file, indefinitely, until +the user stops the application. + +### 2.3. util_spi_stress ### + +This software is used to check the reliability of the link between the host +platform (on which the program is run) and the LoRa concentrator register file +that is the interface through which all interaction with the LoRa concentrator +happens. + +### 2.4. util_tx_test ### + +This software is used to send test packets with a LoRa concentrator. The packets +contain little information, on no protocol (ie. MAC address) information but +can be used to assess the functionality of a gateway downlink using other +gateways as receivers. + +3. Changelog +------------- + +### v1.3.0 ### + +* Added TX power management. +* Added full support for SX1301 reference board. +* Changed build system with configuration for multiple chip/radio/band support. +* SX125x bandwidth set to 1MHz by default (was 800 kHz). +* Solved warnings with 64b integer printf when compiling on x86_64. +* Renamed helper programs to reduce the concentrator vs. gateway confusion. + +### v1.2.2 ### + +* Added a GPIO toggle on the FTDI SPI module to reset the SX1301 board. + +### v1.2.1 ### + +* Fixed 'floating point exception' crash when concentrator returned a packet with SF=0 (CRC error on LoRa header). +* Fixed buggy timezone handling. + +### v1.2.0 ### + +* Added feature: new GPS module in the library for synchronization. +* Removed feature: no more missed deadline detection in TX because of incompatibility with GPS. +* Added documentation for GPS and legal notice. +* Added flags in Makefiles for easier cross-compilation. + +### v1.1.0 ### + +* Fixed bug 'no TX on radio B' (rfch 1). +* Added feature: concentrator processing delay compensation in the receive() function for accurate 'end of packet' even timestamping. +* Added feature: TX 'start delay' compensation in the send() function to emit packet exactly on target timestamp. +* Added feature: timestamp counter verification in send() function, return an error if scheduling was too late. +* Switched license to 'Revised BSD'. + +### v1.0.0 (from beta 8) ### + +* Switched FTDI as default SPI phy layer in library.cfg. +* Fixed a bug in TX power control; still only two TW power available, 14 and 24 dBm. +* Changed library directory name from loragw_hal to libloragw to follow usual conventions. + +### Beta 8 (from beta 7) ### + +* API: lgw_receive now return info on RX frequency and RF path for each packet (no need to keep track of RF/IF settings). +* Unified some portion of the code with the 470 MHz variant of the HAL (use SX1255 radios instead of SX1257). +* Improved AGC and ARB firmwares. +* Adding -Wall -Wextra for compilation, fixing all the new warnings for cleaner code. +* Fixed bugs in handling of FSK datarate. +* test_loragw_hal now dumps the content of all LoRa registers after configuration in reg_dump.log. + +### Beta 7 (from beta 5) ### + +* Reduced number of SPI transactions to fetch a packet (improved number a packets par second that can be downloaded from concentrator). +* Streamlined build process, main target is now a static library: libloragw.a. +* Change memory allocation for payload: they are now part of the struct for TX/RX, no need to malloc/free. +* All RX chains can use any of the two radios now. +* FSK is available and working in TX and RX (variable length mode). +* Calibrated RSSI for FSK. +* lgw_connect now check the CHIP_ID. +* Added a license file and a changelog. +* Added a function returning a version string to allow identification of the version/options once compiled. + +### Beta 6 ### + +Private release, not taken into account in that changelog. + +### Beta 5 (from beta 4) ### + +* Updated registers, firmware and configuration to align with r986 bitstream revision. +* Calibrated RSSI for LoRa "multi" and LoRa "stand alone" modems. +* Renamed some confusing TX status code. +* Added preliminary FSK support. + +### Beta 4 (from beta 3) ### + +* Unified build environment with selectable SPI layer (Linux native or FTDI SPI-over-USB bridge). +* Remove the 500 kHz limit on radio bandwith, back to the nominal 800 kHz. +* Renamed debug flags. + +4.

Introduction +---------------- + +This software is used to scan the RF band and measure background RSSI and some +measurement of interferer pattern. +The RSSI is purposefully skew towards high values, to detect high power +interferers (eg. a gateway installed in the beam of a powerful base station), +and not to characterize the noise floor, or accurately measure the time-domain +profile of interferers. + +2. Dependencies +---------------- + +This software call functions in the loragw_reg and loragw_reg sub-modules of +loragwlib. loragw_spi is used indirectly, and the loragw_hal sub-module is not +used at all, except for constants define at the top level. + +It has been qualified with the LoRa concentrator HAL library version 1.3.0, and +should be compatible with any compatible later version that use the same API, or +a downward-compatible one. + +Because some non-public functions from loragw_hal had to be re-implemented, any +change in the IP might affect this program even if an updated LoRa concentrator +HAL library is provided. +Connecting an incompatible concentrator board should give you the error: +"ERROR: fail to connect to concentrator board" + +3. Usage +--------- + +To stop the application before the end of the measurement, press Ctrl+C. + +By default, the program scans the whole band (start and stop frequency defined +in the loragw_hal.h file) with a 200 kHz measurement step. +Use -f option to change start and stop frequency, and measurement step. + +The resolution bandwidth of the scan is 200 kHz and cannot be set by the user. + +The measurement results are put in a CSV file whose name include a UTC timestamp +of measurement starting time in ISO 8601 recommended compact format: +yyyymmddThhmmssZ (eg. 20131009T172345Z for October 9th, 2013 at 5:23:45PM UTC) + +4.

Introduction +---------------- + +This software is used to set up a LoRa concentrator using a JSON configuration +file and then record all the packets received in a log file, indefinitely, until +the user stops the application. +No filtering is done and all packets that are LoRa packets with the correct RF +parameters (frequency, datarate, bandwidth) should appear in the log. + +2. Dependencies +---------------- + +This program uses the Parson library (http://kgabis.github.com/parson/) by +Krzysztof Gabis for JSON parsing. +Many thanks to him for that very practical and well written library. + +This program is a typical example of LoRa concentrator HAL usage for receiving +packets. + +Only high-level functions are used (the ones contained in loragw_hal) so there +is no hardware dependencies assuming the HAL is matched with the proper version +of the hardware. +Data structures of the received packets are accessed by name (ie. not at a +binary level) so new functionalities can be added to the API without affecting +that program at all. + +It was tested with v1.3.0 of the libloragw library, and should be compatible +with any later version of the library assuming the API is downward-compatible. + +3. Usage +--------- + +To stop the application, press Ctrl+C. + +The only optional parameter when launching the application is the log rotation +time (in seconds). + +The way the program takes configuration files into account is the following: + * if there is a debug_conf.json parse it, others are ignored + * if there is a global_conf.json parse it and look for the next file + * if there is a local_conf.json parse it +If some parameters are defined in both global and local configuration files, the +local definition overwrites the global definition. + +The global configuration file should be exactly the same throughout your +network, contain all global parameters (parameters for "sensor" radio channels) +and preferably default "safe" values for parameters that are specific for each +gateway (eg. specify a default MAC address). + +If you have build the libloragw library for a specific radio band (eg. ETSI +868 MHz band) a ready-to-use global_conf.json file is generated by the Makefile +with a set of channels typical for a 'LoRa MAC' network application. +If you don't specify a radio band, an empty global_conf.json is generated and +must be filled with the settings you need. + +The local configuration file should contain parameters that are specific to each +gateway (eg. MAC address, frequency for backhaul radio channels). + +In each configuration file, the program looks for a JSON object named +"SX1301_conf" that should contain the parameters for the LoRa concentrator board +(RF channels definition, modem parameters, etc) and another JSON object called +"gateway_conf" that should contain the gateway parameters (gateway MAC address, +IP address of the LoRa MAC controller, network authentication parameters, etc). + +To learn more about the JSON configuration format, read the provided JSON files +and the API documentation. A dedicated document will be available later on. + +The received packets are put in a CSV file whose name include the MAC address of +the gateway in hexadecimal format and a UTC timestamp of log starting time in +ISO 8601 recommended compact format: +yyyymmddThhmmssZ (eg. 20131009T172345Z for October 9th, 2013 at 5:23:45PM UTC) + +To able continuous monitoring, the current log file is closed is closed and a +new one is opened every hour (by default, rotation interval is settable by the +user using -r command line option). +No packet is lost during that rotation of log file. +Every log file but the current one can then be modified, uploaded and/or deleted +without any consequence for the program execution. + +4.

Introduction +---------------- + +This software is used to check the reliability of the link between the host +platform (on which the program is run) and the LoRa concentrator register file +that is the interface through which all interaction with the LoRa concentrator +happens. + +2. Dependencies +---------------- + +This program only access the LoRa concentrator HAL library through its +loragw_reg "named registers" access sub-module. + +It was tested with v1.3.0 of the libloragw library, and should be compatible +with any later version of the library and the hardware, assuming the registers +used for the tests are still present. + +The registers used are: + * LGW_VERSION + * LGW_IMPLICIT_PAYLOAD_LENGHT + * LGW_FSK_REF_PATTERN_LSB + * LGW_RX_DATA_BUF_ADDR + * LGW_RX_DATA_BUF_DATA + +A data buffer accessible through the 2 registers above must be implemented. + +3. Usage +--------- + +The tests run forever or until an error is detected. +Press Ctrl+C to stop the application. + +When an error is detected, diagnosis information are displayed. Please refer to +the source code for more details on what is displayed for diagnosis. + +All tests use pseudo-random data generated by the rand() function. The random +generator is not seeded, and the same sequence of data will be use each time the +program is launched. + +Basically, some random data is written, read back and then compared to the +initial written data. Some "useless" read on others registers might be inserted +to be sure that the data read back is coming from the hardware, and not from the +internal buffer(s) of the software driver(s). + +Test 1 > R/W on a simple 8-bit register + +Test 2 > R/W on a simple 8-bit register with interstitial reads on VERSION + +Test 3 > R/W on a 32-bit register (short SPI bursts access) + +Test 4 > data buffer R/W (long SPI bursts access) + +4.

Introduction +---------------- + +This software is used to send test packets with a LoRa concentrator. The packets +contain little information, on no protocol (ie. MAC address) information but +can be used to assess the functionality of a gateway downlink using other +gateways as receivers. + +2. Dependencies +---------------- + +This program is a typical example of LoRa concentrator HAL usage for sending +packets. + +Only high-level functions are used (the ones contained in loragw_hal) so there +is no hardware dependencies assuming the HAL is matched with the proper version +of the hardware. +Data structures of the sent packets are accessed by name (ie. not at a +binary level) so new functionalities can be added to the API without affecting +that program at all. + +It was tested with v1.3.0 of the libloragw library, and should be compatible +with any later version of the library assuming the API is downward-compatible. + +3. Usage +--------- + +The application runs until the specified number of packets have been sent. +Press Ctrl+C to stop the application before that. + +Use the -f option followed by a real number (decimal point and scientific +'E notation' are OK) to specify the modulation central frequency. + +Use the -s option to specify the Spreading Factor of LoRa modulation (values 7 +to 12 are valid). + +Use the -b option to set LoRa modulation bandwidth in kHz (accepted values: 125, +250 or 500). + +Use the -p option to set the concentrator TX power in dBm. Not all values are +supported by hardware (typically 14 et 20 dBm are supported, other values might +not give expected power). Check with a RF power meter before connecting any +sensitive equipment. + +Use the -t option to specify the number of milliseconds of pause between +packets. Using zero will result in a quasi-continuous emission. + +Use the -x option to specify how many packets should be sent. + +Use the -i option to invert the LoRa modulation polarity. + +The packets are 20 bytes long, and protected by the smallest supported ECC. + +The payload content is: +[T][E][S][T][packet counter MSB][packet counter LSB] followed by ASCII padding. +All LoRa data is whitened, so the padding has no influence whatsoever on the +packet error rate. + +4.
