SX126x HAL

[klim4685e]

Contribution description

It's a HAL implementation for Semtech SX126x driver. Basically created for RAK3172 module (STM32WLE5CC).

Testing procedure

tests/ieee802154_hal: set the SYMBOL_TIME 256 (2^SF/BW*1000000) us
Run and you should see:

• Correct ACK replies after transmission
• Correct address filter
• CCA

Problems

ACK doesn't work in tests/ieee802154_submac.
I've got noack event

Issues/PRs references

TODO

MOVED TO #19172

Thanks @3JIouHoCoK

I got a kernel panic (with the lora-e5-dev board):

The assertion error is fixed with this change to the drivers/sx126x/sx126x_radio_hal.c file:

+#ifdef BOARD_RAK3172
 #define SX126X_TIMER                        TIMER_DEV(1)
+#else
+#define SX126X_TIMER                        TIMER_DEV(0)
+#endif

Hi @jdavid
It's because only 1 timer is defined in lora-e5-dev board . I add an extra one in periph_conf.h (see on /stm32/include/cfg_timer_tim2_tim1.h), because with TIMER_DEV(0) I had some problems with shell.

I don't receive anything:

• Using 2 LoRa E5 boards (STM32WLE5JC)
• I changed SYMBOL_TIME to 256 as stated in this PR description (tried as well with 1024)
• Using TIMER_DEV(0) as told above (no problems with the shell here)

Any idea what could be wrong?

Hi @jdavid

I have not problems with running ieee802154_hal with TIMER_DEV(0), but sending in ieee802154_submac sends "event" process to mutex. I didn't dive deeply in this problem, but just try add an extra timer :)

why was this closed? :(

@jia200x I wipe my repo accidentally :D Tommorow I will restore it
