Can Bangle.js 2 app disconnect from phone and later reconnect?

I know that Bangle.js 2 only supports one Bluetooth connection at a time, but is it possible to make an app that does the following:

(Bangle.js 2 is connected to Android phone and Gadgetbridge on that phone)

• app disconnects Bangle.js 2 from phone
  
• app connects Bangle.js 2 to some other device
  
• app disconnects Bangle.js 2 from that other device
  
• app reconnects Bangle.js 2 back to the phone
  
  

(Bangle.js 2 is again connected to phone and communication with Gadgetbridge continues normally)
