Where is the school that 8 yo kids are building such complicated projects? Try to move this code from handle_OnConnect to loop: float temp = dht.readTemperature(true); float humid = dht.readHumidity(); soilVal = analogRead(soilSensor); int soil = map(soilVal, 3350, 1500, 0, 100); //soil = constrain(...

Did you try arduino as component?

4. maybe this one https://github.com/espressif/esp-idf/tree/master/examples/system/console 2. try this https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/kconfig.html#using-sdkconfig-defaults you can create file with default values for your project, then `make defconfig` will do the...

Maybe its some misunderstanding here, what exactly "factory reset" means? Is it reset to state esp32 module is leaving factory or your device is leaving factory and is sent to client?

When you discover GATT attributes you get all attributes with corresponding handles. Use handles to read/write characteristics.

And how exactly you re-init BLE, full procedure?

Few months ago ive been doing OTA over BLE example and sha has been working with master (it was v4.0), but now i am trying to do the same with PlatformIO esp-idf framework and this is what i found: [0;32mI (440) cpu_start: Application information:␛[0m ␛[0;32mI (445) cpu_start: Project name: platform...

I cant say about classic bt or esp-now, but with BLE you can have at best 6-10ms delay.
There is also wifi LR mode.
