Tx Power setting through the Registers.

[Venkata Bharath]

Hi, 

We tried by changing the Tx Power in nrf52840 through the register values as mentioned in the document nRF52840_Product_Specification_v1.10 and Page no 636, but it is not reflecting in the BT Tester (Spectrum Analyzer).  So can you please help how to change the Tx Power.

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.
