Huzzah ESP8266 Breakout not working properly

Post by afcaveman »

I just received my 8266, and I am unable to get it into bootloader mode, so that I can flash it. I ordered: https://www.amazon.com/dp/B0131V0WYI?ps ... ct_details
I found that I was using a regular FTDI USB RS-232 converter (usb-rs232-we-1800-bt) instead of usb-rs232-we-1800-bt _ 3.3. I have since ordered the correct cable, but do I need to order a new 8266? Just wondering if I fried it or not... I did also try a usb-rs232-we-1800-bt _ 5.0 cable as well, without any luck.

The issue I had with the unit is that I found if I didn't connect the Tx line, I was able to get it into bootloader mode, but as soon as I would connect it, the red light would go out completely instead of going to the dim state.

Thanks

Agree with above. If the ESP8266 saw actual RS232 voltage levels, then there's a good chance the RX/TX pins saw got over voltage inputs and are likely damaged. If timing is not critical, can always try with correct cable and see what happens.
