Follow the Server Deployment Guide at
- Logoff from app
- Switch Region at Logon Screen to Custom. At next screen give your local server IP address.
- Sign in new (local) useraccount
- If you have success, you should see the Grove Example & Grove_ds18b20 in the app menu under"Groves"
- Solder the 4,7k resistor & pins to the grove protoshield, as shown at the picture
- Connect the resistor with Vcc and S0
- Connect the sensor cables to the right pins (Vcc, Ground, Data = S0)
- Connect the protoshield to D1 connector of the Wio Link. Only D1 (= Pin12) works, it's hardcoded in the driver. I'm not a programmer. If someone could write better code, feel free to do so.
This all isn't perfect, but works for me :-)
