Pico and ESP8266

Does it need to be connected?

No, I'm pretty sure there's a pullup/down resistor internally.

Uncaught no 'ready' after at+rst..

Your code would have uploaded fine, this is the general error message you get if there is no communication with the ESP8266.

Are you using an ESP8266 that came with the Espruino Pico KickStarter, or another one? ESP8266s all come with different firmwares which have different baud rates and subtly different AT command sets.

• You could also try soldering a capacitor across the power lines on the ESP8266. It seems that when using jumper wires the resistance/bad contacts mean that ESP8266 can be a bit flakey.
  
• Is the red light on the ESP8266 lit up? Does the blue light light up at all?
  
• Also, are you sure that RX goes to TX and vice versa?
  
  

If you're getting other errors, please can you post up the exact ones? People have posted up a bunch of different errors here.
