B4R Question ESP32 BLE mesh chat

[peacemaker]

HI, All

If to build a wireless network of sensors that sends data to a PC - i guess, ESP32 batch can be used.
1. One is a BT-receiver at PC USB port, and others works as sensors - BT-senders.
2. Unique ID for each ESP32 module must be set up, for sure: "project_sensorXX" and "project_receiverYY"
3. And then, if to make the chat - any module can send info to any: each sensor can send measured info to the PC receiver. It should be strings formatted somehow like

"<sensor_channel>X value</sensor_channel>"

, where X = channel ID (means temperature, humidity ... or other measured parameter)

Correct ?

Classical Bluethooth with pairing one to another - is not correct way, only BLE is needed, correct ?
So, question - do we have such code example to use EPS32 BLE as a text chat ?

ESP32 Mesh example

Taken from here: https://randomnerdtutorials.com/esp-mesh-esp32-esp8266-painlessmesh/ The example uses the "painlessmesh" library. Just add it via arduino's library manager. Other libs will be added, to (like JSON, etc.). To download the needed "asynctcp" lib go to...
