Reply To: RN2903A based device does not join (OTAA) Conduit AP anymore

Worked with Multitech support and posting some details in case the next developer runs into the same issue.

Attempted solutions
They suggested I try to manaully reset the packet forwarded (“Packet forwarder not seen” debug). This might work for the next reader of this post, but did not work for me; I got a segmentation fault. Sending hardware back to Multitech for investigation.

Suggested course of action if you’re experiencing the same issue: Contact Multitech Support directly.
