There are standalone devices with integrated keyboard for typing messages. I’d expect them to be able to store a lot of messages, regardless of firmware version. Imagine someone sent 7 “test” messages to Primary channel and thus wiped your DM’s. Doesn’t feel right.

What about MeshCore, can it operate as a mailbox? Mailbox mode will be extremely convenient.

it’s not really meant to operate as a “mailbox” where you can retrieve the messages later

Why not, where’s bottleneck? Internal memory is too small? Packets are 255 bytes each, doesn’t seem like there’s much to store.

Hmm maybe this is what I want: https://github.com/brad28b/meshtastic-cli-receive-text But I can’t install it currently, I get python stack trace instead…

UPD. Fail. I’ve managed to launch it, but it is same as “listen”, it receives only new messages in real time.

How did you use it in this trip? Did you chat in public groups? Have you used it to keep in contact with someone specific?
