Can't connect to a LYWSD03MMC that has the at1441 Release 78 firmware with the pvvx Flasher #402

This happens when I try to connect with the Flasher on this site:

9:26:28: Searching for devices 19:27:12: Get Advertising MAC (Web Experimental Features!) 19:27:12: Connecting to: ATC_xxxx 19:27:50: MAC: xxxxxxxxxx, Bat: 99%, Vbat: 3097 mV, Temp: 22.9°C, Humi: 50%, Count: 3 19:27:55: TypeError: getDevVersion(...).then is not a function 19:27:55: Reconnect 1 from 5 . . 19:29:16: Disconnected.

Tried both with Android 12 device and Windows 10 / Edge with Web Experimental features enabled. Tried removing battery too. Works with the Flasher from at1441

You need to dl the firmware and use the TlinkOTA flasher to upgrade first time. I juste did it two times few minutes ago.

Thanks! I had also found my courage to try it after I wrote the note. Worked here too but maybe the compatibility could be easily improved.

Firmware from atc1441 does not have any identifiers that can be used to determine what kind of firmware it is.

jorkkiporkki commented 8 months ago

Thanks for the quick response. All good now, Maybe in the future you could agree on an identifier with Aaron to make it easier.

They are typical for all BLE devices and are described in the standard.
