Fixed and tested.

Sorry for forgetting to update the repository.

For compatibility, I adopted the following fw numbers:

/* Board ID */
#define BOARD_LYWSD03MMC_B14     0
#define BOARD_MHO_C401  1

You can get original or modified Bluetooth firmware here and flash it via USB to UART

Added a paragraph about reverting to BLE over UART

[pvvx]

Zigbee OTA firmware files for recovery in BLE

[devbis]

@pvvx Are these firmwares tested? Can I recomment them in the project readme?

[pvvx]

This is a typical firmware with headers for Zigbee OTA.

[devbis]

I made such experiments it they failed in 50%. What would happen if BLE firmware is written to address 0x40000?

Thank you !! :)
