Communication / Bluetooth PRO:

» BT Pro 09: Sleep mode

This example shows how to use sleep mode of Bluetooth module

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

Do not confuse Bluetooth sleep mode and Waspmote sleep modes.
Bluetooth module wakes up through UART. Take into account that if you send bytes through same socket where bluetooth module is connected, It will be woken up.
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.
