If it cann't get bluetooth working?
Using Node32s as the Board selection. To reference GPIO pins in code use just the number, for example "digitalWrite(13, HIGH)" sets GPIO13 high. The built-in LED to GPIO2.

5.0 out of 5 stars Nice well-made board
Reviewed in the United States on 27 September 2017
Nice well-made board. No physical defects, no problem connecting to my wifi network and communicating with websites. Still haven't been able to get bluetooth working (other devices can see it but cannot pair with it). Programming with Arduino IDE works fine right out of the box, using Node32s as the Board selection - this took a while to figure out without documentation. To reference GPIO pins in code use just the number, for example "digitalWrite(13, HIGH)" sets GPIO13 high. The built-in LED is attached to GPIO2. For pinouts see attached image, which I found helpful since the pin labels are on the underside of the board.
