An example using Python 3 code to send a message to the mesh, get and set a radio configuration preference:
|
|
|
|
```python
|
|
import meshtastic
|
|
import meshtastic.serial_interface
|
|
|
|
# By default will try to find a meshtastic device,
|
|
# otherwise provide a device path like /dev/ttyUSB0
|
|
interface = meshtastic.serial_interface.SerialInterface()
|
|
# or something like this
|
|
# interface = meshtastic.serial_interface.SerialInterface(devPath='/dev/cu.usbmodem53230050571')
|
|
|
|
# or sendData to send binary data, see documentations for other options.
|
|
interface.sendText("hello mesh")
|
|
|
|
ourNode = interface.getNode('^local')
|
|
print(f'Our node preferences:{ourNode.radioConfig.preferences}')
|
|
|
|
# update a value
|
|
print('Changing a preference...')
|
|
ourNode.radioConfig.preferences.gps_update_interval = 60
|
|
|
|
print(f'Our node preferences now:{ourNode.radioConfig.preferences}')
|
|
ourNode.writeConfig()
|
|
|
|
interface.close()
|
|
```
|
|
|
|
Another example using Python 3 code to send a message to the mesh when WiFi is enabled:
|
|
|
|
```python
|
|
import time
|
|
import meshtastic
|
|
import meshtastic.tcp_interface
|
|
from pubsub import pub
|
|
|
|
def onReceive(packet, interface): # called when a packet arrives
|
|
print(f"Received: {packet}")
|
|
|
|
def onConnection(interface, topic=pub.AUTO_TOPIC): # called when we (re)connect to the radio
|
|
# defaults to broadcast, specify a destination ID if you wish
|
|
interface.sendText("hello mesh")
|
|
|
|
pub.subscribe(onReceive, "meshtastic.receive")
|
|
pub.subscribe(onConnection, "meshtastic.connection.established")
|
|
interface = meshtastic.tcp_interface.TCPInterface(hostname='192.168.68.74')
|
|
while True:
|
|
time.sleep(1000)
|
|
interface.close()
|
|
```
|
|
|
|
Note: Be sure to change the IP address in the code above to a valid IP address for your setup.
|
|
|
|
You can get and update settings like this:
|
|
|
|
```python
|
|
import meshtastic
|
|
import meshtastic.serial_interface
|
|
interface = meshtastic.serial_interface.SerialInterface()
|
|
|
|
ourNode = interface.getNode('^local')
|
|
print(ourNode.radioConfig.preferences)
|
|
ourNode.radioConfig.preferences.gps_update_interval = 60
|
|
print(ourNode.radioConfig.preferences)
|
|
ourNode.writeConfig()
|
|
|
|
interface.close()
|
|
```
|
|
|

For the rough notes/implementation plan see [TODO](https://github.com/meshtastic/Meshtastic-python/blob/master/TODO). See the API for full details of how to use the library.

## A note to developers of this lib
|
|
|
|
We use the visual-studio-code default python formatting conventions (autopep8). So if you use that IDE you should be able to use "Format Document" and not generate unrelated diffs. If you use some other editor, please don't change formatting on lines you haven't changed.
|
|
|
|
If you need to build a new release you'll need:
|
|
|
|
```shell title="Command"
|
|
apt install pandoc
|
|
sudo pip3 install markdown pandoc webencodings pyparsing twine autopep8
|
|
```
