We're using CYW920706WCDEVAL and ModusToolbox 2.3. We set BR/EDR Tx Power either by modifying 'max_pwr_db_val' in 'hci_ag_cfg_settings' or by calling 'wiced_bt_dev_set_tx_power()' API.
Does the Tx Power we set remains constant all the time the service-layer connection exists? If not, can we influence it, for example, disable automatic power adjustment?

Yes the Tx power set after connection should remain constant for the whole connection time.

Hi @KoFo_4760836 ,
If you set the Tx power using wiced_bt_dev_set_tx_power() after a connection, the Tx power will be maintained throughout the connection time with that device. Otherwise the Tx power in the firmware will be considered.

Hi @SheetalJ ,
Thank you for the answer! But my question is actually: does the Tx Power we set remains constant all the time the service-layer connection exists? If not, can we influence it, for example, disable automatic power adjustment?

So, you mean, if we set Tx power to 4 dBm and do not see in our air traces LMP_POWER_CONTROL_REQ or similar requests from the peer device to change the power, we can assume the Tx power of our CYW920706WCDEVAL is always 4 dBm, right?
