Any suggested APIs to setup BLE transmit power in NCS?

the set_tx_power() in the Zephyr example looks not work with nordic softdevice controller.

Hi,

Have a look at this example, it should work with the softdevice controller out-of-the-box.

Which version of NCS are you using? It seems like you are getting an issue that was fixed in v1.3.0, have a look at the change log: 

Under "Added": 

• Added support for the Vendor specific HCI command: Zephyr Write TX Power Level (per Role/Connection).

I've tried it with v1.4.2 and 1.5-RC1

Hi, 

Are you running the example I referred to? Or a custom application? 

Can you give more details about your setup?

There are a number of posts indicating that it is a softdevice problem. Please try it yourself, then advise when it may be fixed.
