I bet that it is sending correctly, but it just isn't being printed correctly upon being received. Can you try building the firmware for the sender (and maybe the receiver also) with the build flag -DLL2_DEBUG? That should show the contents of the packet as it is passed along through the LL2 library functions.

I will try to reproduce with my t-beam.

I remember the problem. I'm missing a +5 to the length. Need to account for the five byte datagram header, that's what's causing the message to be truncated. I'll fix this and resolve this issue with my next commit.
