Bug Description

For a while now I'm unable to pair with my car kit. It's a reverse-pair procedure, so the car is trying to initiate the pairing, shows the PIN to enter and goes "failed" - with the phone never showing anything.

Syslog shows, possibly relevant:

Apr 20 15:21:40 ubuntu-phablet bluetoothd[891]: src/device.c:new_auth() Requesting agent authentication for 00:1A:77:F6:D5:2B

It seems like a Settings bug that has been fixed a while ago and reopened afterwards.

What I have found in the syslog:

15:21:25 here the car is connecting to the phone, the bluez correctly handles the device:

src/adapter.c:connected_callback() hci0 device 00:1A:77:F6:D5:2B connected eir_len 5
src/device.c:device_create() dst 00:1A:77:F6:D5:2B

src/device.c:device_set_class() /org/bluez/hci0/dev_00_1A_77_F6_D5_2B 0x300408

15:21:26 next the car is disconnecting. The reason 3 means Remote Disconnected and status 0xe means Status Disconnected.

src/adapter.c:dev_disconnected() Device 00:1A:77:F6:D5:2B disconnected, reason 3

src/adapter.c:bonding_attempt_complete() hci0 bdaddr 00:1A:77:F6:D5:2B type 0 status 0xe

15:21:32 8 seconds later we see that the pin code request callback has kicked in

Apr 20 15:21:32 src/adapter.c:pin_code_request_callback() hci0 00:1A:77:F6:D5:2B
Apr 20 15:21:32 src/device.c:device_create() dst 00:1A:77:F6:D5:2B

Apr 20 15:21:32 src/agent.c:agent_ref() 0xb782a140: ref=2
The pairing request is send to the registered agent however it is denied:

Agent /com/canonical/SettingsBluetoothAgent/adapteragent replied with an error: org.bluez.Error.Rejected, The request was rejected: RequestPinCode

As a result the bonding obviously fails:

src/adapter.c:btd_adapter_pincode_reply() hci0 addr 00:1A:77:F6:D5:2B pinlen 0
src/agent.c:agent_unref() 0xb782a140: ref=2

src/device.c:device_bonding_complete() bonding (nil) status 0x0b
src/device.c:device_cancel_authentication() Canceling authentication request for 00:1A:77:F6:D5:2B
src/device.c:device_bonding_failed() status 11

src/device.c:device_free() 0xb7837780

15:21:40 8 seconds later the pin request callback is called again and the whole thing repeats with the same result.
