I brought out one of mine that I bought sometime back and didn't actually use, and it looks like these boards have some sort of demo firmware in them by default (not the AT command set that Espruino or Arduino is expecting).
You can check if yours is the same by turning it on and seeing if you have something like "ai-thinker" show up in your wifi networks.
If I connect to mine with the password "ai-thinker" and go to
I see some information as a webpage, which tells me mine does NOT have the AT commandset.
You might need to flash your own firmware on the shield in that case as mentioned here https://www.espruino.com/ESP8266#updating-esp8266-firmware
Maybe others might have more ideas that don't involve flashing the wifi devboard? It's relatively easy for me so I don't really think twice about it, but others might have a different technique.
