I’m using Dot-Examples (https://developer.mbed.org/teams/MultiTech/code/Dot-Examples/) and trying to get the OTA example running on my mDot connecting to The Things Network.

I set it as a public network, subband 2 (here in USA), and set my AppEUI and AppKey appropriately.

I’ve performed the join with a different piece of hardware, but using the same AppEUI/AppKey/DevEUI. Join comes in and the servers immediately respond with a Join Accept.

Using the mDot, I can see the join request arrive at the TTN servers, but there is no join accept response. My only hypothesis is that there is something different about the way the mDot encrypts the MIC token that causes it to be rejected by TTN.

Has anyone successfully joined the TTN network with an mDot?

Thanks!
