Communication / Bluetooth Low Energy:

» 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.
