Are FSK & GMSK supported?

Open whid-injector opened this issue 7 years ago • 2 comments

Hi, I quickly looked at the exmaple sketch and I didn't find any llace were is defined the modulation. Shall infer it is hardcoded to ASK? Or somewhere is possible to switch between those modulations supported by cc1101?

Hi there, thanks for opening this!

If I understand correctly, the modulation is set here: https://github.com/veonik/arduino-cc1101/blob/master/src/cc1101.cpp#L236 I'm not sure what additional procedures, if any, need to occur when changing the modulation during runtime, however. If you get a chance to try it out, I'd love to hear the results!

Cheers

Hi, I was digging a bit more and I found this: The modulation registry is on MDMCFG2: https://github.com/SpaceTeddy/CC1101/blob/6f34280a4cd34d409b3f00087b38723b1a409785/cc1100_raspi.cpp#L1010

//-------[set Modulation type 2-FSK=0; GFSK=1; ASK/OOK=3; 4-FSK=4; MSK=7]------
