OK, let me update my request a bit. If I use the linked configuration file, it partially works-ish, sorta. I still never see the Microtech mote successfully join. However, I do see the request come through the basic_pkt_forward program and into my LoRa Network Controller instance... but I need to retry the join a number of times. (I'm guessing that the Microchip mote is going to randomly hit all 72 channels and I only see the request when I get lucky and the request falls inside the sub-band in which the frequencies align to the packet forwarder.) So, then I decided to disable all of the channels on the Microchip mote except for those in my sub-band (48-55). Now, every first request replies with "no_free_ch" and then the next request will go over the RF and I'll see the entire communication but the join will eventually return "denied" -- which I'm guessing is a timeout condition.
Has anyone seen anything like this specifically with the 915Mhz setups? I can work without any issues at all using the same settings on the 868 Mhz setup.
Thanks a ton!.
