Release v3.1 · sigfox-tech-radio/sigfox-ep-lib

v3.1 - 01 Mar 2023

Add MCU_API_timer_status() function to facilitate timeout management in RF API functions.
Add logical names for timers (MCU_API_TIMER_INSTANCE_xxx macros) in MCU API to define instances mapping.
Add reason field in timer structure.
Add RF_API_get_latency() function to compensate radio delays in MCU API timers duration.
Add new bypass flags in test API for RFP addon (ul_enable, dl_enable, dl_decoding_enable, dl_conf_enable, ldc_check_enable bits, rx_frequency_hz, cs_max_duration_first_frame_ms, and dl_t_w_ms / dl_t_rx_ms timing values).
Add Low Duty Cycle (LDC) check in TX control.
Add MCU_API_print_dl_payload() function to print RFP addon downlink results.

Rename fields of message status and split error flag into execution_error and network_error to differentiate internal execution errors from external errors such as TX control failure or downlink reception timeout.
Move SIGFOX_UL_BITSTREAM_SIZE_BYTES macro in inc/sigfox_types.h to avoid core files inclusion in manufacturer drivers.
Improve manufacturer functions call sequence (Tw timer and downlink ending).
Random frequency generator: optimize RAM footprint and increase allowed bandwidth of N=1 and N=2 modes.
Remove all function pointers in blocking mode for specific compilers compatibility.
Change default 32 bits type to long.
Rename sigfox_ep_version.h to sigfox_ep_lib_version.h.
Use RETURN macro in manufacturer functions template.

Buffer overflow in downlink frame decoding functions (src/core/sigfox_ep_bitstream.c).
Wrong application message pointer access in blocking mode (src/sigfox_ep_api.c).
Wrong LBT carrier sense timeout computation for second and third frames (src/core/sigfox_tx_control.c).

Remove dl_phy_content_size field in RX data structure, as it is fixed to SIGFOX_DL_PHY_CONTENT_SIZE_BYTES.
