v3.1.0

• Removed GPIO module from HAL, that was specific to IoT Starter Kit platform. GPIO configuration will be done
• Removed CFG_BRD configuration from library.cfg, not needed anymore.

v3.0.2

• Bugfix: Fixed frequency calculation on uplinks: lgw_receive() function was using a variable to calculate the frequency before it was initialized with correct value.
• Bugfix: util_pkt_logger crashed when no gateway_ID is not defined in global_conf.json

v3.0.1

• Bugfix: Fixed util_tx_continuous compilation issue, by adding empty obj directory
• Bugfix: Fixed HAL compilation issue for CFG_SPI=ftdi, removed dependency on loragw_gpio in this case

v3.0.0

• Added new HAL function lgw_board_setconf() to configure board/concentrator specific parameters: network type
• Added new HAL function lgw_txgain_setconf() to configure concentrator TX gain table. It can now be dynamicall
• Changed HAL function lgw_rxrf_setconf(), it will now also configure the radio type (CFG_RADIO has been remove
• Added support of IoT Starter Kit platform, which is now the default board.
• Added util_tx_continuous utility for gateway TX power calibration and spectral emission measurements/qualific
• Removed CFG_BAND configuration from library.cfg. Band configuration is done by application and passed dynamic
• Updated makefiles to allow cross compilation from environment variable (ARCH, CROSS_COMPILE).

** WARNING: **
** Known issue: a problem with carrier leakage calibration has been seen on 433MHz boards. **

v1.7.0

• 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.

v1.6.0

• 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

v1.5.0

• Feature: Adding option to discriminate LoRa MAC networks from private LoRa networks at PHY level

v1.4.1

• 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

v1.4.0

• Feature: Added calibration routine to optimize RF performance
• Feature: Added support for SX1301 433 MHz reference board
• Improved AGC firmware
• Improved RSSI accuracy
• Improved utilities Makefile

v1.3.0

• Feature: Added TX power management.
• Feature: Added full support for SX1301 reference board.
• Feature: 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.
