Connect UART RTS to the RST pin of the ZTU module. 
There is a simple version of the programmer with reading: https://github.com/pvvx/TlsrComSwireWriter - [TLSR825xComFlasher.py](https://github.com/pvvx/TlsrComSwireWriter/blob/master/TLSR825xComFlasher.py)
Problematic Flash? Doesn't correctly return Write In Progress (WIP) bit to Status Register? Is +3.3V (and GND) power supply connected? [TLSR825xComFlasher.py](https://github.com/pvvx/TlsrComSwireWriter/blob/master/TLSR825xComFlasher.py) For testing, I added a delay after Erase Sector....
> removed first 0x3d bytes (seems to be a header of Zigbee OTA?) and flashed to the module, and it worked! https://github.com/pvvx/ATC_MiThermometer/raw/refs/heads/master/TS0201_v48.bin
To disable the display of the device in the system menu of Windows and other systems, you must disable the transmission of “AdFlags”.  Then the "Bluetooth" integration in Home...
_[README](https://github.com/pvvx/ATC_MiThermometer): Support for Zigbee firmware is in the [ZigbeeTLc](https://github.com/pvvx/ZigbeeTLc) repository._ MHO-C401 exists in 3 versions. As of today, Zigbee firmware only supports [MHO-C401N](https://pvvx.github.io/MHO_C401N/). https://github.com/pvvx/ZigbeeTLc/issues/95#issuecomment-2114938699
Будет работать Zigbee OTA. Можно произвести [специальную Zigbee OTA прошивку для возврата в BLE](https://github.com/pvvx/ATC_MiThermometer/tree/master/zigbee_ota).
В Zigbee OTA файл вписаны идентификаторы. В итоге другая прошивка, от другого типа устройства, не воспримется. Для Zigbee OTA прошивки на другое устройство требуется изменить бинарный заголовок на необходимые ID....
