Do you have to be always connected to your node? (mander.xyz)

  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.

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.

    AFAIK, yes, memory. There are a lot more packets than just text messages. Telemetry, node info, positions/waypoints, etc.

    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.

    No, it's a hardware limitation. There's only so much memory on these little devices, and once it's full, it starts replacing old messages.

    I wonder how many messages can it store. I will try leaving my node for a day and will see timestamp of earliest messages and how many there are. Also, maybe it worth checking out firmware source code. Different devices can have different limit.
