Communication / Bluetooth Low Energy:

» BLE 18 Sleep mode

This example show how to manage BLE sleep mode. * Do not confuse BLE sleep mode with Waspmote sleep modes.

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.

Output

E#
BLE_18 Example
Bluetooth module sleeping.
BLE MAC is: 000000000000
Bluetooth module alive.
BLE MAC is: 000780789EEB
