Operating RF433 with TD1208

by disk91 Wed Jun 10, 2015 12:44 pm

I would be interested in configuring the TD chip to listen on 433 Mhz AM / OOK modulation. Is is possible to reconfigure the chip to operate in this mode, gather information, then pushing over SigFox ?
If yes, How ?

Sincerely,
Paul

We don't have yet an API to access the required low-level RF chip configuration and data handling.

Yes, it is possible without hardware modification, however it won't be optimal because there is an harmonic filter in the RF path, but it is not very steep, so we only loose a few dB.

You will need to change the antenna, though, s oyou won't be able to do both 433 MHz and 869 MHz for Sigfox at the same time.
