I apologize in advance for errors in the text, because I translated from Russian into Google translator.
I propose adding the following simple but very useful functions in Meshtastic
- On any of the free GPIOs, anyone can solder a button. The device code processes the click of a button and as a result sends a distress signal (SOS) in the form of a text message. In addition, in the Android application, you can program an audio response to receive a text distress signal. Together with the distress signal, you can also update the current GPS coordinates of the position of the device.
Why is it important to introduce this function? Many use the Meshtastic network in hard-to-reach places, in the wild. When a person gets into trouble, he often does not have the opportunity and time to get a bluetooth-enabled smartphone, turn it on, unlock it, and then type a message. But if directly in the LoRa module you will have a button. It is very convenient and efficient.
Adding this feature can be done easily. A couple of lines of code are enough.
- It would be nice to add the ability to process control text commands… I will give an example.
From an android device, you send text such as “GpXOn” to node Meshtastic. Node Meshtastic having received this text, turn ON Gpio X. Turning on or off one or two Gpio is quite enough.
What can be turned on or off through the network Meshtastic?
- security camera
- alarm system
- watering plants
- Feeding troughs or drinking bowls for animals
These two functions could seriously expand the functionality and scope of the network Meshtastic
Some time after the publication of this message, I found that this function was previously discussed here:
