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.

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.
