- Tue Nov 24, 2015 9:06 am #34878 I've never seen that. Did you update the firmware for v0.9.2.2 using the instructions of the website I gave to you? Could you see the progress from 0% to 100% of this process?

My suggestion: burn the firmware again, after updated remove the wire from GPIO0 (the gray one) from GND and leave it unhooked. Then, use Cool Term (my prefered) and open a communication with 9600 baudrate. Type AT and see if it returns an OK.
