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: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/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_free() 0xb7837780

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