2015-03-11v2.0.0HEADmasterMatthieu Leurent9
- Added support for Kerlink 868 27dBm gateway - Updated global_conf.eu868.json (in packet logger) to new LoRaWAN frequency plan - Added version numbers to AGC, arbiter and calibration firmware (those versions are checked at startup) - Added test_loragw_cal to test radio calibrations - Fixed minor bug in error coverage in register read/write functions /!\ warning: Kerlink 868 27dBm gateway includes a FPGA that MUST be programmed before running any application
2015-02-05v1.7.0v1.7.0Sylvain Miermont4
- Added TX “start delay” compensation for timestamp mode (fix time window alignment issue at low SF and/or high BW) - Added adaptive narrowband/wideband TX filtering for LoRa - Added a command-line option to set CR in util_tx_test - Added notes for TX “start delay” in immediate and triggered mode /!\ warning: due to start delay compensation being implemented, TX that were previously 1.5ms late will be sent on time. At low datarate, this is not an issue. At high LoRa data rate (and FSK) you might have to adjust your timing.
2014-10-27v1.6.0v1.6.0Sylvain Miermont9
- Fixed bug with 250kHz and 500 kHz TX filtering - Adjusted FSK timestamp calibration in RX for accurate RX/TX alignment - Added lgw_abort_tx() function to stop a TX at any time (scheduled or ongoing) - Added support for user-settable FSK sync word (same for RX and TX) - Added support for the Chinese 780 MHz band - Added support for Kerlink 433 gateway - Added support for Cisco 433, 470 & 780 MHz concentrators boards
2014-06-27v1.5.0v1.5.0Sylvain Miermont3
- Adding option to discriminate LoRa MAC networks from private LoRa networks at PHY level.
2014-06-27v1.4.1v1.4.1Sylvain Miermont5
- Enabling support for FSK per LoRa MAC specification - Adjusting TX and RX calibration set on 868 reference board - Added specific RX/TX calibration set for Kerlink 868 "IoT station" gateway - Changed default SPI port for native driver to Kerlink SPI device number
2014-05-15v1.4.0v1.4.0Sylvain Miermont7
- Added calibration routine to optimize RF performance - Added support for SX1301 433 MHz reference board - Improved AGC firmware - Improved RSSI accuracy - Improved utilities Makefile
2014-03-28v1.3.0v1.3.0Sylvain Miermont26
- 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.
2014-03-10v1.2.2v1.2.2Sylvain Miermont3
- Added a GPIO toggle on the FTDI SPI module to reset the SX1301 board.
2014-01-27Fixed 'floating point exception' crash when concentrator returned a packet ↵v1.2.1Sylvain Miermont4
with SF=0 (CRC error on Lora header). Fixed buggy timezone handling HAL does not return NaN anymore for SNR and RSSI if measurements are not available (return -128).
2013-12-19v1.2.0v1.2.0Sylvain Miermont12
- 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
2013-12-12v1.1.1v1.1.1Sylvain Miermont6
- bugfix: fixed some range checks that did not prevent segfaults - test: removed systematic register dump in test_loragw_hal.c - modified Makefiles for easier cross-compilation - added root README and removed TXT extension of other READMEs
2013-11-22v1.1.0v1.1.0Sylvain Miermont18
- 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'
2013-10-24v1.0.0v1.0.0Sylvain Miermont4
- 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
2013-10-24Beta 8v1.b8Sylvain Miermont14
- 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
2013-10-23Beta 7 (beta6 skipped)v1.b7Sylvain Miermont24
- API: change memory allocation for payload, they are now part of the struct for TX/RX, no need to malloc/free - reduced number of SPI transactions to fetch a packet (improved number a packets par second that can be downloaded from gateway) - streamlined build process, main target is now a static library: libloragw.a - 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
