Hey,

Does anyone have a solution for this?

You can do this by setting the data rate: bool dataRate(uint8_t dr)
dr can be between 0-6 (I have tested this, and 6 doesn't work, but all the rest does)
/*
   DataRate    Modulation    SF    BW    bit/s
   0    LoRa    12    125    250
   1    LoRa    11    125    440
   2    LoRa    10    125    980
   3    LoRa    9    125    1'760
   4    LoRa    8    125    3'125
   5    LoRa    7    125    5'470
   6    LoRa    7    250    11'000

But also check this issue (SF does not change if you do not set ADR on).
