Rak 7200 not respoding at AT command

So now the question is whether the gateway communicates with the node, can any data be seen on the server during the join?

Gateway and node of the antenna is not removed! From the log found that the rssi is very bad!

welan · April 9, 2020, 6:57am

Many thanks for your support, I resolved the issue!

Nicholas · April 9, 2020, 6:59am

Could you tell me what caused it?

welan · April 9, 2020, 7:09am

The error 91 was related to the blank channel list, switched from EU868 to AU915 and back again. After this, all the channel table was correctly populated.
The last problem was related to the signal, I moved the RAK7200 in other postion and it joined the network, however, all my previous test had been made in that position.

Nicholas · April 9, 2020, 7:32am

Okay,thank you!
