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.
