Sigfox require BPSK (D-BPSK), however, S2-LP provides only FSK derivates of modulation schemes. Can somebody explain the trick how the modulation scheme is configured on S2-LP to accommodate SigFox differential phase shift keying for uplink and downlink?

[Streammaster]

I should first read the S2-LP data sheet completely before I was asking the question as I find the answer on it: " The Direct Polar Mode is suitable to implement differential binary phase shift keying modulation (DBPSK) such as the data modulation used by the SigFox protocol".

So this is a theoretical answer to how it is achieved :smiling_face_with_smiling_eyes:!

Now it would be nice if there is

an example of register

configuration for such DBPSK (and encoded bytes which need to be sent to

TX_FIFO).

Can anyone help with this?
