Hi,

I'm working on ADR in a ABP example project. When setting the ADR to 1, The device starts sending at SF12. It won't change SF even though the RSSI is around +10 dB. This is my code, any thoughs?

@LiamDoumen Any updates on this?

after 4 years something?

trlafleur commented 12 months ago

There are a number of complete LoRa radio that support AT commands that are very easy to use, cost less than RFM 95, with complete LoRa stack inside. Look at Seeed E5 and others

LMiC is Obsolete! Or should be!
