1. Only certain frequencies are currently supported by the driver. The frequency can be specified by the 3-byte register FRF for the sx127x chip. For details see the datasheet.
|
|
|
|
Example:
|
|
freq = 868.1E6
|
|
temp = int(freq * 2**19 / f_xosc)
|
|
lsb = temp & 0xFF
|
|
mid = temp >> 8 & 0xFF
|
|
msb = temp >> 16 & 0xFF
|

2. Spreading factors 11 and 12 do not work correctly with LoRaWAN. Possible reason: TTN mandates the use of 'Low datarate optimization' at these spreading factors. Maybe we can enable this in the driver?
