how can i use stm32wl55jc to transmit CW beacon?

[scora.1]

I have nucleo-wl55jc board i want to transmit CW beacon.

i am able to transmit continuous wave but not able to sleep the radio and continue next transmit.

What would be the possible way to start and stop radio quickly?

Hello @scora.1​ ,

Sorry for the delay.

You can configure the device to keep in retention the config of the chip and restore it when you will leave sleep mode.

This can be done using the following function in radio_driver.c :

void SUBGRF_SetSleep( SleepParams_t sleepConfig )

You have to set the parameter at the index 2 at 1 to enable this feature.

(Table from DS_SX1261-2-V2_1)

I suggest you to refer to the Reference Manual RM0461, section 4.7.2 about Sleep Mode of the radio to have further information.

I hope this help

Best regards

Louis
