This article explains the perfect and imperfect conditions for maintaining your Bluetooth connection during a Remote Assistance session.

By default, the WorkLink App uses the default speaker of your device for audio transmission during Remote Assistance. However, the App is able to recognize Bluetooth connections as a secondary option but struggles when an active WorkLink session is interrupted or when the app is in the background (inactive) before connection. 

S/N	Scenarios/Conditions	Work-Around
1	Perfect Scenario: Confirmed Bluetooth device is connected to iPhone. Users log in to the WorkLink App on iPhone and another supported device (e.g. Samsung) - Both users are active on the App. User on Samsung calls the user on the iPhone. The iPhone rings through the Bluetooth device. Call connects successfully with audio transmitting through the Bluetooth device. Audio is perfectly transmitted on both the Samsung device and the Bluetooth device for iPhone.
2	Imperfect Scenario 1: Confirmed Bluetooth device is connected to iPhone. Users log in to the WorkLink App on iPhone and Samsung devices - Both users are active on the App. User on Samsung calls the user on the iPhone. The iPhone rings through the Bluetooth device. WorkLink Call connects successfully with audio transmitting through the Bluetooth device. A phone call comes through to the iPhone, interrupting the WorkLink Call. iPhone returns to WorkLink Call but Bluetooth is disconnected. Audio is now transmitted through the iPhone speaker, even though the Bluetooth device is still connected to the phone.	Workaround 1: While still on the WorkLink Call, go to the iPhone control center, tap the Bluetooth icon to quickly disable and re-enable it. Audio will be restored to the Bluetooth device. Workaround 2: End the call and close the App on the iPhone by swiping up from the bottom of the screen, then relaunch the App. Audio will be restored to the Bluetooth device on your next call.
3	Imperfect Scenario 2: Confirmed Bluetooth device is connected to iPhone. Users log in to the WorkLink App on iPhone and Samsung devices - The iPhone user is not active on the App (e.g. phone is locked, user is using the device for other things other than WorkLink, WorkLink app is “backgrounded”) User on Samsung calls the user on the iPhone. The iPhone user picks up the call from the background. Call connects successfully but audio transmits through the iPhone speaker.	Workaround 1: While still on the WorkLink Call, go to the iPhone control center, tap the Bluetooth icon to quickly disable and re-enable it. Audio will be restored to the Bluetooth device. Workaround 2: End the call and close the App on the iPhone by swiping up from the bottom of the screen, then relaunch the App. Audio will be restored to the Bluetooth device on your next call, if both users are active on the WorkLink App when the call is placed.
Rare issue: No audio on both ends of the call.		Both users should close their apps by swiping up from the bottom of the screen, then relaunch the App.
