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. - This example can be executed in Waspmote v12 and Waspmote v15
