bt set tx power

how to set bt tx power in NCS

I referred to this example "hci_pwr_ctr", but err occurs:"Set Tx power err: -5 reason 0x00",Possible errors are BT_SCI-ERR_SUNKNOWN_CMD。

How can I configure and use it correctly？

Hi Albert,

Have you tried to test with the hci_pwr_ctr sample ? Do you have the same problem ? 
I suspect that you forgot to add CONFIG_BT_CTLR_TX_PWR_DYNAMIC_CONTROL=y to the project configuration.
