Hi All,
I have a Things Indoor Gateway on my TTN console. I have a TTGO board with the LMIC LoRaWAN library. I wanted to send data through the gateway and see it on my end device console. I was able to successfully send “Hello, World” message however I have noticed that I started getting the “Link ADR rejection received” message on the end device console. On the Gateway console, I see a lot of uplink and downlink messages being sent. All the uplink messages are empty and I am not sure how my TTGO board is sending these messages. I am attaching some screenshots of the console

The end device is connected to the TTN through ABP. Any help will be appreciated
Hello, I have the same problem but using OTTA, the strange thing is that, today in the morning, the problem was solved, but when adding a temperature sensor and loading the new firmware, once again there is the problem.
Have you already solved the problem?

Hello again, I just read in the LMIC documentation, that the default MAC version is v1.0.3 and I had v1.0.2 selected, all this at the frequency of us915, I made the change in the Node configuration and apparently, it was solved, Greetings!

Have you checked your device has the adr option activated? I faced the same long time ago and it was because I was forcing the Data Rate instead of using the Adaptive Data Rate.
