Thanks, cobra! Looks like either I’ve done something wrong, or I’ve got at least one faulty card.
The obvious thing for me to try is to factory reset the devices - but they’re still not responding to the Factory Reset command in the Meshtastic app.
Anyone know the secret for factory resetting the T1000-E?
EDIT:
Tell a lie, the Factory Reset command does work in the latest alpha firmware - just not on the stock firmware. (Well, it hangs at 0% - but the cards themselves do reset correctly!)
Now, to see if that fixes things…
EDIT 2:
No difference. Factory reset both cards, changed nothing except choosing EU_868, and they’re exactly the same as before: the only device shown is the one the phone is currently connected to, and messages fail with a line-through-a-cloud. I think we can rule out something I’m doing wrong, then - looks like I’ve at least one bad card.
Disappointing!
EDIT 3:
Restored the factory firmware (I took a copy of CURRENT.U2F before flashing the beta and alpha firmware builds): same. They’re absolutely blind to each other. It’s possible only one is faulty, but without a third to test how would I know which one!
