I was trying to purchase a Wifi shield and ended up with a D1 Wifi module. Cute but probably won't work as a shield. I plugged it in to the USB port on my pc and opened the Arduino IDE serial console. Sent an AT command and it gives the response "locked $" ....no matter what command or lack of is sent...same response.
Any ideas what to do with this board? What do I have to do to use it as a wifi module?
