:::warning GPIO access is fundamentally dangerous because invalid options can physically damage or destroy your hardware. Ensure that you fully understand the schematic for your particular device before trying this as we do not offer a warranty. Use at your own risk. :::

:::note This plugin requires attaching a peripheral accessory to your device. It will not work without one. It also requires use of the Rotary Encoder Plugin to configure the input source. :::

Overview

The CannedMessage Plugin will allow you to send messages to the mesh network from the device without using the phone app. You can predefine text messages to choose from.

:::tip Once plugin settings are changed, a reset is required for them to take effect. :::

Settings

Setting	Acceptable Values	Default
canned_message_plugin_allow_input_source	rotEnc1, _any	_any
canned_message_plugin_enabled	true, false	false
canned_message_plugin_messages	string	""
canned_message_plugin_send_bell	true, false	false

canned_message_plugin_allow_input_source

Input event source accepted by the canned message plugin.

Value	Description
_any	Default. Allows any peripheral input device connected to the device.
rotEnc1	Hardcoded value naming the input device that this plugin listens to. This could allow multiple input devices to be named with future software development. At present, this doesn't do anything differently than the default setting.

Details

Prerequisites

• Attach a compatible peripheral device. Take note of the GPIO numbers you use, as they will be used in the following step.
• Once attached, configure peripheral device with Rotary Encoder Plugin Settings.

:::note Replace each GPIO (x3) below with the GPIO numbers from hardware setup.

meshtastic --set rotary1_pin_a GPIO
meshtastic --set rotary1_pin_b GPIO
meshtastic --set rotary1_pin_press GPIO
meshtastic --set rotary1_event_cw KEY_UP
meshtastic --set rotary1_event_ccw KEY_DOWN
meshtastic --set rotary1_event_press KEY_SELECT
meshtastic --set rotary1_enabled True

::: That's it! With a functioning and enabled rotary encoder, you're ready to begin configuring the Canned Message Plugin.
