ios system upgrade, I use qt to develop ble app connection failed

After ios system upgrade, the ble app I developed with qt failed to connect. After iOS system upgrade, the ble app I developed would fail to create the service and return NULL. I want to know which permissions related to Bluetooth were upgraded by iOS, because I did not find the corresponding permissions in Xcode,and the uuid is correct
