Spreading Factor indications

[Michael]

In my code, that I lifted from an online example (mDot_DS18B20), I have a call to set the spreading factor to: SF_12
dot->setTxDataRate( mDot::SF_12 );
(note that SF_12 is part of an enum and set to 16)

The debug window that runs says “SF: 10”
2. TX Frequency: 903500000 SF: 10 BW: 125 kHz POW: 11 dBm

So, why the difference or are they really the same (16 decimal = 10 hex)?

For US915 the minimum datarate is DR0 – SF10BW125
