Hi,

   

    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

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

Hi,

   

 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???

Tanks, very useful. Need to remember that enabling the PA will increase the absorbed current by 2.5 mA, so you need to manually manage the enable/disable of PA as explained on "Power Saving Measures with PA/LNA Operation" section of "CYBLE-224110-00 EZ-BLE PSoC XT/XR Module Datasheet.pdf"

Hi,all: According to AN96841 guideline, I only can get about -30dBm PA output by handset detection. But it faraway with the 9.5dBm. So, Who could help provide a program or profile to prove it?
