Esp01 Not working
Posted: Sat Nov 30, 2019 9:45 pmI have been using two ESP01 modules along with temperature sensors to read indoor temperature. I am using tasmota firmware and was working properly. Today I suddenly find that it is not working. When I switch the power on, the blue indicator led blinks just once and then nothing. Usually it blinks repeatedly. After this ,fearing of flash errors, I connected it to computer using ttl to usb connector, I was able to erase and flash it with new firmware. There was absolutely no issue with erasing and flashing these ESP01 but then again it wont boot. I tried it with other two spare sensor modules and even powered it up directly through 3.3v but then again a single led blink only, no network or no functioning. Please advise what to do?
