TX output power control

The STA2500D supports output power control with advanced features:

●

Basic feature:

–

With the standard TX power control algorithm enabled, the STA2500D will adapt

its output power when a remote BT device supports the RSSI feature; this allows

the remote device to measure the link strength and to request the STA2500D to

decrease/increase its output power. In case the remote device does not support

the RSSI feature, the STA2500D will use its ‘default’ output power level.

●

Advanced features, available via specific HCI commands:

–

Enhanced power control feature: allows the STA2500D to decrease autonomously

its output power until the remote BT device, supporting the RSSI feature, requests

to increase the output power.
