I have this log Log: 15:00:05: Searching for devices 15:00:08: Connecting to: ATC_F2FA4A 15:00:11: Detected custom Firmware 15:00:16: Disconnected. 15:00:28: Searching for devices 15:00:53: NotFoundError: User cancelled the requestDevice() chooser. 15:00:53: Reconnect 1 from 5 15:01:04: Disconnected. 15:01:04: NetworkError: GATT Server is disconnected.

What could be wrong ? I cannot connect to the device so I cannot download a previous firmware.

Thanks in advance for you help

yeah I have this too, did it brick yours?

Same issue.... can't connect after flashing the latest custom firmware. Any body have any ideas? or is it time to buy a new sensor.

atc1441 commented 2 years ago

You can always recover via UART.

What hardware revision is it?

If 2.0 please try out victors firmware version

Gaarbaard commented 2 years ago

I don't have a usb to uart on hand and a new sensor is about the same price locally. It was version 2. My problem was originally that every time I used telink to connect to the stock firmware the bind key would change. My esp found the device but couldn't retrieve the sensor temp and humidity. Hence trying the custom firmware so a dummy bind key would work. Thanks for the advice!

Can confirm, release 75 78 stuck at "Detected custom Firmware". Tried removing battery, doesn't help.

Same for me.

Cant connect anymore

Had the same issue. Stuck on "Detected custom firmware", but I tried to select stock firmware file and Flash and it worked, stock firmware successfully flashed!
