Hello, I would like to set parameters such as CR,SF,BW etc. I cannot find this in the Sparkfun guide or anywhere else. Thx.

Well I don’t really like looking into the bowels of libraries but I did find this:

// Set up default configuration

// No Sync Words in LORA mode.

setModemConfig(Bw125Cr45Sf128); // Radio default

// setModemConfig(Bw125Cr48Sf4096); // slow and reliable?

setPreambleLength(8); // Default is 8

// An innocuous ISM frequency, same as RF22’s

setFrequency(434.0);

// Lowish power

setTxPower(13);
