## About
|
|
|
|
This is a simple interface to send messages over the mesh network by sending strings over a serial port.
|
|
|
|
Default is to use RX GPIO 16 and TX GPIO 17.
|
|
|
|
## Basic Usage:
|
|
|
|
1. Enable the plugin by setting `serialplugin_enabled` to `1`.
|
|
2. Set the pins (`serialplugin_rxd` / `serialplugin_rxd`) for your preferred RX and TX GPIO pins. On tbeam boards it is recommend to use:
|
|
* RXD 35
|
|
* TXD 15
|
|
3. Set `serialplugin_timeout` to the amount of time to wait before we consider your packet as "done".
|
|
4. (Optional) In SerialPlugin.h set the port to `PortNum_TEXT_MESSAGE_APP`if you want to send messages to/from the general text message channel.
|
|
5. Connect to your device over the serial interface at `38400 8N1`.
|
|
6. Send a packet up to 240 bytes in length. This will get relayed over the mesh network.
|
|
7. (Optional) Set `serialplugin_echo` to `1` and any message you send out will be echoed back to your device.
|
|
|
|
:::note
|
|
The device must be restarted after the settings have been changed for the plugin to take effect.
|
|

|
|
|
|
## TODO (in this order):
|
|
|
|
* Define a verbose RX mode to report on mesh and packet infomration.
|
|
|
|
:::note
|
|
This won't happen any time soon.

## Known Problems
|
|
|
|
* Until the plugin is initilized by the startup sequence, the TX pin is in a floating state. Device connected to that pin may see this as "noise".
|
|
* Will not work on NRF and the Linux device targets.
