Communication / Bluetooth Low Energy:

» BLE 15 get set own name

This example shows how to read /write BLE friendly name

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.
