xsns_62_esp32_mi_ble.ino - MI-BLE-sensors via ESP32 support for Tasmota

Version yyyymmdd Action Description
--------------------------------------------------------------------------------------------
0.9.2.1 20210217 changed - make features alos depend on received data - i.e. 'unknown' devices will show what they send.
Add MI32Option6 1 to switch to tele/tasmota_ble/<somename> style MQTT independent of HASS discovery.
-------
0.9.2.0 20210127 changed - Officially includes as the mi driver when using USE_BLE_ESP32.
-------
0.9.1.9 20201226 changed - All change now.
-------
0.9.1.7 20201116 changed - small bugfixes, add BLOCK and OPTION command, send BLE scan via MQTT
-------
0.9.1.6 20201022 changed - Beacon support, RSSI at TELEPERIOD, refactoring
-------
0.9.1.5 20201021 changed - HASS related ('null', hold back discovery), number of found sensors for RULES
-------
0.9.1.4 20201020 changed - use BearSSL for decryption, revert to old TELEPERIOD-cycle as default
-------
0.9.1.3 20200926 changed - Improve HA discovery, make key+MAC case insensitive
-------
0.9.1.3 20200916 changed - add ATC (custom FW for LYWSD03MMC), API adaption for NimBLE-Arduino 1.0.2
-------
0.9.1.2 20200802 changed - add MHO-C303
-------
0.9.1.1 20200715 changed - add MHO-C401, refactoring
-------
0.9.1.0 20200712 changed - add lights and yeerc, add pure passive mode with decryption,
lots of refactoring
-------
0.9.0.1 20200706 changed - adapt to new NimBLE-API, tweak scan process
-------
0.9.0.0 20200413 started - initial development by Christian Baars
