ESP8266

[oliveritech]

Hello, I was able to upload and configured the ESP. But when I connect Lasergrbl V3.0.10 say connected and instead of clear text, there are only question marks ????
Can't figure this out, it is probably some configuration that I miss.. Can some one help me out please. Thank you

Hello, I flashed the ESP8266 with your telnet sketch and now just say ‘esp8266 connected’ nothing else and no grbl controll. Connecting to port 23 on the IP address from a terminal program I could see the ESP8266 prompt, so I know the module really works.

Connecting to port 23 on the IP address from a terminal program I could see the ESP8266
prompt

What do you mean "I could see the ESP prompt?"

If you connect to port 23 via terminal (ie. telnet to esp IP) you should interact with your arduino, soo you should receive welcome message and reply to $$ or G-Codes commands. This because my telnet sketch redirect ALL telnet to serial tx-rx that should be connected to arduino serial.

Are you sure of your connection between ESP serial lines and Arduino tx-rx?

I mean that from the PC Putty terminal I see ‘ESP connected’ and no interaction whit the Arduino. I did connect the TX from ESP to Arduino RX and ESP RX to Arduino TX. I’m going to clear the flash on the ESP and reload the telnet sketch in the morning Il giorno sab 30 mar 2019 alle 00:20 arkypita <[email protected]> ha scritto:

Did you connect Arduino to ESP directly or with 3.3v to 5v level shifter? Did you put an electrolitic capacitor near ESP vcc-gnd? Sometime it help
