I m new with BLE and totaly stupid about it. I would like to know how to use the PA integrated for more range(db power).
thanks in advance
Please refer section 23 in the below Application Note:

I think it s not what I seek. The CYBLE-224110-00 have an internal PA/LNA. This chip is a SE2438T. The ble module is XT (extented range).It can output 9.5 db for 400 mt range.My question is : how I can change the power transmission to 9.5db? In the BLE COMPONENT iI can only choise the 3db power.
"This chip is a SE2438T" There is no chip inside a PSoC except the PSoC itself. And I never heard about a power amplifier for a BLE. Probably you need to explain a bit more what you are referring to.
the CYBLE-224110-00 it s a new product with extended range (400mt ! 9.5 db power output). I buy the dev kit few days ago. If you seek the datasheet on page 1 on description or page 14 there are the schematics and you can see this IC.
Now I understand!
Apparently the output of the PA is controlled by the SE2438T supply voltages Vcc, Vcc1 and Vcc2. See SE2438T datasheet, table 6 pg. 8
I check the datasheet, to control the PA there are 4 control pin. This pin set the state of the PA (standby, TX,Receive and power or bypass ).
I think this pin need to be controlled from BLE component to switch correctly from transmit or receive mode.So maybe I have to wait a new version of this component???
PROBLEM SOLVED...I opened a ticket and I have a fast response!
