Detect signal strength of connected Bluetooth device

Post by Wibbly » 19 Feb 2015 16:18

Is there a way using General Broadcast (or any other method) to determine Bluetooth signal strength? I want an indicator/estaimation of how close a connected Bluetooth device is...

The example Bluetooth Device found in trigger General Broadcast provides a variable rssi with the signal strength to the flow. The broadcast will be sent when you execute a bluetooth device scan in the bluetooth settings page. It will probably not work for already connected devices but I have not tested this. I also heard that executing a bluetooth device scan uses quite a lot of battery and can cause problems with already connected bluetooth devices.

The next version of Automagic also provides the signal strength of BT Low Energy devices when condition Bluetooth LE Device Available is executed.
