Introduction to Bluetooth troubleshooting

There are two main Bluetooth problems that can occur:
Detachment of the BT antenna.
Malfunction in the BT ASIC, BB ASICs or Phone's BT
SMD components.
The main issue is to find out if the problem is related to the BT antenna or related to the BT system or the
phone's BB and then replace/fix the faulty component.

Description
This would most likely happen if the device has
been dropped repeatedly to the ground. It could
cause the BT antenna to become loose or partially
detached from the PWB. (see the following section
for details on BT antenna HW and mechanics)
This is unpredictable and could have many causes
i.e. SW or HW related.
