How to change Output Radio Amplifier Power and then test the byte error, package error of nrf5340?

[Cong Ma]

Hello, I have managed to get two NRF5340s linked and measured their throughput. Now I need to change their Output Radio Amplifier Power to test again.  And then I also need to test the byte error and package error of the nrf5340.How can I do this?

many thanks.

Hi there,

Are you using the BLE or the radio directly?

Have you seen our radio test example?

I use the bluetooth/thoughput sample. Do I need to add or change some codes?

Hi,

Yeah, that is a good sample. See this thread on how to change the TX power.

Hi

Thank you for the reply. I have looked at the link and I referenced this example samples/bluetooth/hci_pwr_ctrl. Now I have added the set_tx_power() function to the  bluetooth/thoughput sample. then some error happen.

I type “Set Tx power err:Neg5dBm reason 0xFB” in the terminal 

then

Set-Variable : Cannot find a position form parameter that accepts the actual parameter "err:Neg5dBm".
Location Line:1 Character: 1
+ Set Tx power err:Neg5dBm reason 0xFB
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Set-Variable], ParameterBindingException
+ FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SetVariableCommand

I cant modify the TX POWER......

Would you happen to know what might be happening?

Thanks in advance.
