Hello! Came across the RAK3172, and using SX126x it should support listening to FSK wmbus telegrams. I can not find enough info of support settings for FSK via AT API. it looks like it support most settings, but I need to check syncword match in code for multiple matches because mode T and C use different. Is it possible to stream data to ring buffer in top-code above RUI3?

Welcome to the forum @EsaveAS
RUI3 does not support FSK wM-Bus. To use it, you have to write a custom application and driver support with STM32CubeIDE.
It seems there is a wM-Bus stack available from Stackforce ==> Wireless M-Bus software stack optimized for the STM32WL series
Thankyou! I guess this violates the RED certification? or is certification bound to hardware only?
CE RED certification is about radio transmission compliance. RAK3172 has full CE certification.
wM-Bus is about supporting the protocol. We support only LoRa P2P and LoRaWAN.
The MCU with its integrated transceiver is able to do FSK.
Very good answer. i have ordered module for test. you may close topic
