CC2651P3: How to turn on high-gain PA

Hi Alex,

To switch on high PA you have to configure it in sysconfig, see the image below:

Where are you calling the HCI_EXT_SetRxGainCmd function in the code? What's more did you check the API references to call properly this HCI command?

regards,

At the end of the "multi_role_init" function, call "HCI_EXT_SetRxGainCmd (HCI_EXT_TX_POWER_P2_20_DBM);"

I am using the example code 'muitl_role', and the default configuration for sysconfig is the same as what you provided without any modifications.

May I ask how to modify the sample code in order to open high gain on your official development board?

Can you tell me how to change the code? I am using the sample code "muitl_role" and the official development board. I have been debugging for a few days, but it is still -40DBM

How can I turn on a gain signal of 20dBm?

Hi Alex,

Receiver gain may be adjusted using the HCI_EXT_SetRxGainCmd(HCI_EXT_RX_GAIN_HIGH)

Transmit power may be adjusted using the HCI_EXT_SetTxPowerCmd()

I need to understand if you want 20dBm transmitting or receiving?

regards,

Excuse me where HCI_EXT_SetRxGainCmd (HCI_EXT_RX_Gain_HIGH) and HCI_EXT_SetTxPowerCmd() are called, we need 20dBm to transmit and receive 

Hello Alex,

What is the package of your CC2651P3, only the 7x7 RGZ package will handle a 20dBm txPower.

Both commands I mentioned you works to set txPower and Rx at 20dBm.

Hi team:

Mutil_role package, the chip is 7x7 RGZ. You mentioned where the two commands should be called, please explain in detail, thank you!

Hi,

You may call HCI_EXT_SetRxGainCmd() & HCI_EXT_SetTxPowerCmd() within your application code in your custom project.

Best Regards,

Jan
