Hello, first off, I know this thread exists: this but I didn’t want to hijack it.
So, the RAK811-h is very un-reliable when connecting to my gateway. I have compaired it to other devices, and everything else seems to work great, it is just the RAK811-h. Before anyone asks, I am running the very latest version of the stable firmware V3.0.0.14.H freshly flashed this evening.
Normally, it takes 3-6 at+join attempts to establish a connection.
When a failure occures I get the error message: error 99. The
in my console (the things stack open source v3.12) I am seeing this under “Recieve join-request”

It will then be direcly followed by a “Drop join-request - Uplink channel not found” message like so:

}
Now, Here is the part where I think I may not understand how this process fully works, If you notice on the “Recieve join-request” claims to be connecting on frequency "frequency": "923800000" Possibly I don’t have the configured in my gateway. Btw, I am connecting on AS923 (JP) so LBT is enabled. Here is my gateway config.
Here is the config of my Gateway (ttog):
As you can see in this picture, I do have 923800… covered. It is easier to see in the LBT Settings page:
So, Here is where I may be mistaken, There are 2 radio interfaces, 0 and 1. I am not sure what the difference is. I do see above, something about Transmit Enabled/disabled, so one may be only send, the other only receive, not sure. can’t find docs on it. Here is where I found the frequencies to set: https://www.thethingsnetwork.org/docs/lorawan/frequency-plans/#as920-923-as1
I am hessitant to make any changes as it is only the RAK811-h chip that has issue connecting, though, possibly there is an issue with my setup, I would like to assume the issue is with me, and not RAK.
While I AM able to establish a connection (after repeated at+join commands) I can transmit some data, and that ALSO only reaches the application. I normally wait 60 seconds before another transmit.
If I check the gateway, I see this error message listed as “Drop uplink message”:

If anyone has any info on this, I would really appreciate it.
Thanks a lot,
