Setting spreading factor

[SmolBumblebee]

Hi, is there a way for me to set the spreading factor?

I hope to get 125 bytes for the max payload; my region is AS923. I've also noticed that whenever I set the data rate, no matter what value I put, it will always print two on the serial monitor, and my max payload size remains 11. If the data rate is 2, shouldn't the max payload be 125? How do I make the max payload to be 125 bytes?

Thank you

The spreading factor is set via setDataRate(). The data rate is region specific. So you need to check out the LoRaWAN spec as to what setting you want to use there.

Thank you so much for your fast reply; I feel so honored to get a response from GrumpyOldPizza ^_^

It turns out that I need to set ADR(false) for the setDataRate() to affect the max payload size.

Is there documentation for the code by chance? I'm a new-bee
