I just received a V4 Expansion Kit. I flashed it with the touch screen version of 2.7.20.1116217
When I send a message, it is not received by another node sitting a few feet away. When I transmit from the other node, no messages are received. Both are correctly set to the same region and to medium-fast.
Is there something I can check to see why it’s not transmitting or receiving? Should I be using a different version of the firmware (I’m wishing I had left it with the firmware it had). If there is a better firmware to use, could you provide a link to where I can download it?
Thanks.
