A Pair of T1000-Es Can't See Each Other

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!
