After the some request the bluetooth crashes Different errors e.g.: connect: Device or resource busy (16) What can I do?

Add some feature to handle the BLE crash: Code: import json import urllib.request import base64 import time import os from mijia.mijia_poller import MijiaPoller, \ MI_HUMIDITY, MI_TEMPERATURE, MI_BATTERY

Settings for the domoticz server

Forum see: http://domoticz.com/forum/viewtopic.php?f=56&t=13306&hilit=mi+flora&start=20#p105255

domoticzserver = "127.0.0.1:8080" domoticzusername = "" domoticzpassword = ""

So id devices use: sudo hcitool lescan

Sensor IDs

Create virtual sensors in dummy hardware

type temperature & humidity

Easiest fix and best working is to add a usb bluetoothstick. Wifi and Bluetooth are on the same chip for pi zero w en pi 3, and i think also for the pi4. Also then disable the internal bluetooth
