» BLE 02 Name scan

This example shows how to make a name scan with Bluetooth low energy, printing number of discovered devices and scan results stored in EEPROM.

Required Materials

1 x Waspmote
1 x Battery
1 x Bluetooth Low Energy module
1 x Bluetooth module antenna
1 x Expansion board (if socket 1 is used)
1 x SD card

Notes

- Socket 0 is used by default
- EEPROM is used in this example by default.
- 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
