- Fri Dec 04, 2015 5:09 am #35625 Hi
I'm having a problem with my ESP8266 breakout module. I have it connected to the PC (win 7) with a CH340G usb-serial converter and use RealTerm or Putty as console. I set them to 9600bd/8b/nopar.

The problem is that when typing I often get faulty characters...It doesn't matter if I simply type, or use the send function of RealTerm (not even when I set long delays between characters)

it should be this

wifi.sta.config("ReinierNet","exxxxxxxxd",1)
wifi.sta.connect()
tmr.delay(1000000)
print(wifi.sta.status())
print(wifi.sta.getip())

but this is on example of what I get (starting at wifsta (already i and . missing))

I bought a new set of ESP8266 en CH340G as I expected the problem to be hardware related. Also I re-installed the driver and tried lualouder as console

however same result

so I'm out of ideas

why do I keep getting faulty characters?????????

- Mon Dec 07, 2015 2:31 pm #35900 yes. connected th GND from USB to the ESP8266 Huzzah board, also the Huzzah is powered by the USB (I also tried an external power unit (with ground connected))

I agree it looks like a GND problem, but that seems to be ok to me
