Detect transceiver version

Semtech Transceivers SX126x family
#1

Hi,

Is there some way to detect which chip of SX126x family is connected to mcu using only software (SPI commands etc.).
I know that for example Nucleo shields use dedicated pin to differentiate between SX1261 and SX1262, however I would like to avoid that solution due to limited GPIOs on mcu. Is there some register that can be read to detect what chip is connected?

Thanks for help,
Tomasz

Hi @tomasz.kasprzak, there is unfortunately no possibility to differentiate a SX1261 from a SX1262 or a SX1268 by reading a register.
