@aniket_yeole you can change some of the parameters (including SF) using setsockopt. To change the frequency you’ll need to remove all channels and re-add channels with your chosen frequency. But beware, the network can change those settings via MAC commands.

Can any of those who have now successfully got class C downlinks working please share some example code? I've been at this all week and like many others here: I can get downlinks in class A or C in the RX window after sending but never outside of it. I'm also interested in some comments on how best to handle downlink messages, I can see some info on defining event driven callbacks but the docs don't make it clear whether this is supposed to be used for both LoRa and LoRaWAN. Otherwise I guess you'd just stop the socket from blocking and try to receive on that socket as part of a main loop, this seems a little messy but I'd just be happy to have it working.

@bmarkus Yes.
