STM32WL33 modulation support for GMSK

[bobbe]

Hi,

The specifications mention multi-protocol support for 4-(G)FSK, 2-(G)FSK, (G)MSK, DBPSK, DSSS, and ASK. However, the reference manual does not explicitly mention GMSK.

Can the device demodulate GMSK directly through register settings, or is it only possible via raw IQ data and external software processing?

Best Regards

Hello @bobbe 

You can use simple 2GFSK modulation, with the difference that you need to select a modulation index of 0.5. Therefore, you should set the proper data rate and frequency deviation.
