  1. Power on your node in the morning. It is not connected to any smartphone or PC via BT/USB/HTTP;
  2. In the evening, connect to it via BT/USB/HTTP;
  3. Access all messages received in Primary channel and/or DMs.

Is it possible? How many messages does a node store in it's internal memory? How to access them via terminal? If node is restarted, are they erased?

I have a Heltec V3. In Meshtatsic CLI there's --listen option, but it's about receiving new packages in real time.

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.
