Hello,

You have to run nrfjprog directly from your system's command line/terminal after installing the nRF Command Line Tools. Make sure nrfjprog is in your system PATH to use it from any location nrfjprog, pynrfjprog - Intro.

It looks like you are trying to use nrfjprog from your output terminal.

You can use this from vs code terminal also.

Open VS Code terminal by selecting Terminal > New Terminal from the menu and this will pop up

Hi,

I have followed this video and flashed the SDK and radio test sample using Visual Studio Code.

And when i tried to set the power as you suggested, it is showing the following error. Please help in resolving this.

Hello,

For example: I have set the TX power 8 dbM in first command. Using the second command I verify the register value is correct.

Can you try to read the register value on the command line using nrfjprog?

Hello,

We are facing issue with reading the register value. Can you help in how to read the register value? We tried using Tera Term, but not able to read.

Thanks

Hello,

How have you set the TX output power? You can set the TX power using the Kconfig option CONFIG_BT_CTLR_TX_PWR_PLUS_<X>, where <X> is the desired power level in dBm. For example, to set the TX power to +8 dBm it will look like CONFIG_BT_CTLR_TX_PWR_PLUS_8

Did you use this command (for examplefor 8dBM) nrfjprog --memwr 0x4000150C --val 0x8?

Can you verify the change by reading register value using this command nrfjprog --memrd 0x4000150C?

Thanks.
