Bulb stop responding after firmware upgrade to Tasmota 8.5.1. No WiFi accesspoint fallback seen.Is there a way to force WiFi accesspoint mode and firmware upload to the bulb when is in this mode?
Tried "Fast Power Cycle Device Recovery" at: https://tasmota.github.io/docs/Device-Recovery/
This did not work. Will be trying serial reflash next...
Any hint as to how to serial flash this device?
Looks like the GPIO pins are exposed. Would you have the pinouts? Need GND, VCC, TX, RX at minimum, and GPIOs would be wonderful!
Thanks!
