Call another phone/text when bluetooth device goes out of range? I want my phone to call another phone/text when a paired bluetooth device goes out of range. Is this possible – and if so, how to achieve it?
You can try automation as an alternative .  I prefer Macrodroid, being easy to learn and free (upto 5 macros)

First pair your devices and confirm 

Create a macro 

Trigger:  Bluetooth event  &rarr; Device disconnected &rarr; Select paired device

Actions: 


Make call  &rarr; select number
Send SMS &rarr; Enter phone number and desired text (Test in screenshot below) on next line 


Constraints​ : Leave blank

Name the macro whatever, save and profit 



Tested on  Android 7.1.2

Note: Initiating call / SMS is not instantaneous on disconnection. There is a pause of about 30 seconds or so during which I guess Bluetooth connectivity is attempted again before it gives up and declares as disconnected
