Hi everyone
Regarding setting method of Tx_Power value of BLE / BDR / EDR.
If we refer to the following site and set Tx_pwer (as datasheet), then we can get below output value.
Configuring Transmit (Tx) Power on CYW20706 Chip - KBA228573
Is the below understanding correct?
BDR / EDR + 12dBm setting → BDR + 12dBm (typ) / EDR + 9dBm (typ) (Can get the output)
BLE + 8dBm setting → BLE + 9dBm (max) (Can get the output)
BTW, check the following information.
The link below is currently inaccessible.
Have you changed to the following site?

Thanks

Hi Yang,
- Please use +8dBm, as the API recommended. If you use +12dBm, the output power is possible to be larger than 9dBm.
- It depends on the configuration of CGS file. Default should be the maximum output power if you don't set any power using API.

Hi Yang,
I will check the issue regarding link https://community.cypress.com/community/wiced-studio-blueooth/wiced-studio-bluetooth-forums/blog/201... . Thanks for pointing it out.!
Also, I do not actually understand your query. As mentioned in Configuring Transmit (Tx) Power on CYW20706 Chip - KBA228573, the maximum possible Tx power is +12 dBm for BR/EDR applications and +9dBm for BLE applications.
Would you please elaborate?

Hi Sheetal,
For BLE, if I set + 8dBm , then I can get output + 9dBm (max) .
Is it correct?
Use below function.wiced_result_t wiced_bt_dev_set_adv_tx_power( int power );
For BDR / EDR, if I set + 12dBm , then I can get output BDR + 12dBm (typ) / EDR + 9dBm (typ).
Is it correct?
Use below function.
wiced_result_t wiced_bt_dev_set_tx_power( wiced_bt_device_address_t bd_addr , int power );
