About
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, 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.
TODO (in this order):
- Define a verbose RX mode to report on mesh and packet infomration. - 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.
