Introduction to Bluetooth troubleshooting

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 next page for details
about BT antenna HW and Mechanics)
This is unpredictable and could have many causes
i.e. SW or HW related.
