Hi,
I have used a MAX232 IC for communication. The communication seems to be working now.
Status of LEDs at Power ON:
red led : constatnt ON
blue led: flashes once
Status of LEDs when Flash is clicked in NodeMCU firmware
red led:constant ON
blue led: flashes continuously
When flash button is clicked, the blue Icon rotates continuously but the progress bar is blank.
I tried connecting RST to Gnd momentarily, as well as swapping RX, TX. Also I changed baud rate from 9600 to 57600 of COM port.
But the firmware doesn't seem to be getting downloaded.
Any suggestions?
Thanks,
Tanmay
