The Canned Message Module 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.
|
|
|
|
The canned message module config options are: Enabled, Save, and Sender. Range Test Module config uses an admin message sending a `ConfigModule.CannedMessage` protobuf.
|
|
|
|
## Canned Message Module Config Values

:::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.
|
|
|
|
This module requires attaching a peripheral accessory to your device. It will not work without one.
|
|
:::
|
|
|
|
## Hardware
|
|
|
|
To navigate through messages and select one, you will require some hardware attached to your device. Currently, the module is tested with a generic rotary encoder, but this is not a limitation further input methods can be added in the future.
|
|
|
|
### Rotary encoder
|
|
|
|
Meshtastic supports hardwired rotary encoders as input devices. (Technically the Canned Message Module is independent of rotary encoders. It is described here, because no other module utilizes rotary encoders just yet.)
|
|
|
|
You will need a generic rotary encoder. The types listed below has five legs where two is dedicated to a "press" action, but any other types will likely do the job. You can also use a three-legged version, where the "press" action should be wired from an independent switch.

Connect your rotary encoder as follows. The rotary encoder has two rows of legs. One of the rows contains two legs, the other contains three legs. Bottom side view:
|
|
|
|
```
|
|
B o --- o PRESS
|
|
GND o | |
|
|
A o --- o GND
|
|
```
|
|
|
|
The two legs is to sense the press action (or push). Connect one of the two to GROUND and the other to a GPIO pin. (No matter which one goes where.) Let's call this connected ports 'PRESS'.
|
|
|
|
The three legs is to sense the rotation action. Connect the middle leg to GROUND and the ones on the side to GPIO pins. Let's call these ports 'A' and 'B', according to the scheme below.
|
|
|
|
```
|
|
A --||
|
|
GND --||]========
|
|
B --||
|
|
```
|
|
|
|
Recommended GPIO pins for connecting a rotary encoder.

|
|
|
- TTGO LoRa V1:
|
|
- A - GPIO-22
|
|
- B - GPIO-23
|
|
- PRESS - GPIO-21
|
|
|
|
There is a reference case 3D-design utilizing the rotary encoder for TTGO LoRa V1:

## Examples
|
|
|
|
- Attach a compatible peripheral device. Take note of the GPIO numbers you use, as they will be used in the following step.
|
|
|
|
:::note
|
|
Replace each `GPIO` (x3) below with the GPIO numbers from your hardware setup.
|
|

|
|
|
|
```shell title="Canned Message Module - Required Rotary Encoder Module Settings"
|
|
meshtastic --set canned_message.inputbroker_pin_a GPIO
|
|
meshtastic --set canned_message.inputbroker_pin_b GPIO
|
|
meshtastic --set canned_message.inputbroker_pin_press GPIO
|
|
meshtastic --set canned_message.inputbroker_event_cw KEY_UP
|
|
meshtastic --set canned_message.inputbroker_event_ccw KEY_DOWN
|
|
meshtastic --set canned_message.inputbroker_event_press KEY_SELECT
|
|
meshtastic --set canned_message.rotary1_enabled True
|
|
```
|
|
|
|
|
|
That's it! With a functioning and enabled rotary encoder, you're ready to begin configuring the Canned Message Module.
