Bluetooth troubleshooting
Introduction to Bluetooth troubleshooting
There are two main Bluetooth problems that can occur:
Problem Description
Detachment of the BT antenna. 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 next page for details
about BT antenna HW and Mechanics)
A malfunction in the BT ASIC, BB ASICs or Phone’s BT
SMD components.
This is unpredictable and could have many causes
i.e. SW or HW related.
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.
