Question

Does the STM32WLEx have the SX126 built in? I have a LoRa-E5 module, and wondered what the difference is. Many Thanks Scott

The STM32WLE contains a licensed IP from Semtech, but no SX126x. The reference manual RM0453 RM0461 (see below) lists all the features of the contained LoRa® part.

The implementation is done on a single die, rather than a stacked die using a discreet SX126x.

The connection is via an internally routed SPI.

The register set/programming for LoRa should be materially the same as for an SX1262​

Hello @Peter BENSCH​  I think the reference manual for the STM32WLE is RM0461.

The RM0453 you mention is for the SMT32WL family.

Thank you for pointing that out, I had actually mixed it up by mistake. Yes, RM0461 is the correct reference manual for the STM32WLE.

You are welcome. If you have experience with the STM32WLE, please take a look at my problem STM32WLE5 'Failure To Execute Command' - I read the reference manual and search the forum, but I can't find an answer to this..
