Today’s Engineering Challenges
Achieving low system power is difficult
Wireless systems often operate from coin-cell batteries
Optimizing system power requires careful use of low-power modes
Battery Drain is a Big Problem Using Active and Sleep Power Modes Can Cut Power Up to 10x

BLE Customizer -> General Tab
The General tab allows general configuration of the BLE Component. This tab contains tools to
load and save configurations as also three main areas for the type of configuration.

Rev *B
BLE Customizer -> Profiles Tab
The Profiles tab is used to configure Profile-specific parameters. It is directly affected by the
choice of Profile settings set in the General tab.

Rev *B
BLE Customizer -> GAP Settings Tab
The GAP parameters define the general connection settings required when connecting Bluetooth
devices. It contains various sections of parameters based on the item you select in the tree. The GAP
Settings tab displays the settings possible based on the GAP role selected in the General tab.

Rev *B
BLE Customizer -> GAP Settings Tab -> Advertisement packet
This section displays when the device is configured to contain "Peripheral," "Broadcaster," or
"Peripheral and Central" GAP role. It is used to configure the Advertisement data to be used in
device advertisements.

Rev *B
BLE Customizer -> GAP Settings Tab -> Security
This section contains several parameters to configure the global security options for the
Component. These parameters are configurable only in Profile mode. If the device is configured
as a GATT Server, you can optionally set each Characteristic using its own unique security
setting in the Profile Tree.
