Q: I saw that there are functions to disconnect the SPP, iAP2 and GATT connection, but the device is still connected in BT/EDR to the phone i am testing with. Is there an easy way to create this complete disconnection?
A: Could you please share the phenomenon of "the device is still connected in BT/EDR to the phone"? Per my understanding, take Android phone connect to SPP device for example: Android phone exchange the link key with SPP device firstly, then open the RFCOM for SPP connection. After SPP disconnected, Android phone do not have BT link with SPP device. Android phone only keep SPP device in paired device list. BLE_GATT is share different link compare to BT.
