I am experiencing issues while trying to connect iOS app with a BLE device, during a call. While not on a call the connection works fine and the phone and the BLE board connect instantaneously, however if there is a call, it's almost like the BT discovery is turned off completely. I looked up everywhere and on Apple dev and couldn't find any info about changes to the discovery or BT antenna attenuation, during a call. Does anyone have any ideas or any links they could point me to ? Thank you !

1Is this your own app or an app from the app store? Do you know if the app supports background processing? – Youssif Saeed May 16 '20 at 08:30

Yes, to both. Problem is also only with certain vehicles. – helpMeCodeSwift Sep 25 '20 at 14:07
