Beta 8v1.b8
- 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

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 Getway HAL library version beta8, 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 Getway 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.
