This example shows how to read Bluetooth module temperature sensor. This value is not very reliable.

Required Materials

1 x Waspmote
1 x Battery
1 x Coin battery
1 x Bluetooth module Pro
1 x Bluetooth module antenna
1 x Expansion board (if socket 1 is used)
1 x SD card

Notes

- Socket 1 will be used to connect Bluetooth module (using expansion board)
- Socket 0 can also be used, plugging module directly.
- It is recommended to set RTC time to your actual time.
- SD card must be inserted to allow saving discovered devices.
- Never unplug module while Waspmote is turned ON.
- Bluetooth module antenna should be connected.
- The battery must be connected in ANY example.
- This example can be executed in Waspmote v12 and Waspmote v15
