ESP8266 pHAT no response in minicom resets with reset.py


#1

I attached the ESP8266 pHAT to my Pi3 and on a fresh install of Jessie (same results if Jessie Light) follow the instructions to setup. When I run minicom, I get no response at all from the 8266, minicom seem sto lock up, the only way to close it is to close the session in putty.
If I follow the blog instruction and create the reset.py file, the 8266 seems to reset when it is executed. With no output in minicom, I’m afraid to try and update the firmware.

Any advice?

Thanks in advance.

Can you post pics of soldering please.

please also detail what steps you have taken so far, for example whether you have ran our one-line installer.

… by default, the Pi3 (and Zero W) use the main UART interface and unless you take steps to modify your system, this won’t work out of the box. Your report seems in line with that being the case (although, yes, it could be a soldering issue, as noted).

I touched up the soldering, there were a few that looked not well covered and that didn’t change anything.

Added the dtoverlay=pi3-disable-bt to /boot/config.txt, again, no change.

Also, I turned on local echo in minicom so I can see what I’m sending.
