- Power on your node in the morning. It is not connected to any smartphone or PC via BT/USB/HTTP;
- In the evening, connect to it via BT/USB/HTTP;
- 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.
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.
