I haven’t done anything with meshtastic since the beginning of the plague. Everything worked great back then. The TTgo T-beam had 12-2019 version of the firmware, but my six androids’ phone/tablets update many times since. I cannot get the channel name or the channel option to change. I cannot get the lock to unlock. I cannot get the share button to share correctly. Also, once paired, it doesn’t want to pair to another TTGO easily. There is no QR code on the page. So, I updated the firmware of the TTGO to the latest version. Still Nada. I have access to 3 Amazon tablets, 1 Leveno, 1 OnePlus phone and LG phone. What’s the secret thing I am forgetting to do?
Did you update the android app on your devices?
There have been many breaking changes and you need to update both the firmware of your device and your android device.
