I have recently purchased a RAK7244.
My problem is that while I have been able to use the ABP protocol with RN2903 and RF95 based devices to interact successfully with thethingsnetwork.org, I have been utterly and repeatedly unsuccessful attempting to use the OTAA protocol, and received only “join denied” or “unable to join” responses. I am new to LoraWAN so it may be a simple issue on my part but I’m clueless about how to troubleshoot. I’ve been very careful about the keys yet some of the example scripts from arduino libraries produce messages such as "there is either a problem with your keys or backend "
I have tested both the “rak_common_for_gateway” software as well as the RAK7244&RAK7244P_based_on_Raspbian_V4.1.0_20191129 software, and have the same result.
“Join Request” and “Join Accept” messages appear in gateway’s Traffic display, and an Activation message appears in Application Data display, but no data and the scripts report Join denied in Serial console. Thus, I’m wondering if the gateway is misconfigured somehow.
Could you help me get started on debugging this problem using OTAA over my RAK7244?
Thanks in advance.
