NUCLEO-WL55JC LoRa register setting

Hi,

Is there any way to read register data in STM32WL? Since it uses SX1262 chip, I want to read register data using the register address. Since STM32WL does not have SPI support, can anyone please suggest how to read register data using STM32WL? For example, how can I read Data Buffer values?

Doesn't it just use an "internal" SPI connection, ie one not getting to external pins, but directly plumbed to the SX1262

The library code surely implements the read/write IO functions, perhaps review that?

Thanks. It does have an internal SPI connection to SX1262. Do we have to use HAL_SUBGHZ_ReadRegister() to read register data?
