QN9080: How to adjust tx power on HCI.

[danieltseng]

I study HCI program. I want to adjust tx power on HCI.

The annotation of "Controller_SetTxPowerLevel()"  understand that it only supports kw40 and kw41.

The following "20" should be about the value range of KW41, not QN9080

I found the following functions that are related to QN9080

I tried to enable it, but it didn't work (always gray)

The following is the adjustment value of qn9080, which is different from 0 ~ 32 of kw41 above.

My questions are as follows

1。Is tx power currently under program control? Or go to the preset 0x7F

2。Is the QN9080 program for adjusting tx power available?
3。How can I adjust tx power by program?

Hello Estephania! 

I've tried the tutorial in the link you provided (Custom HCI command), although it didn't work because the fsl_xcvr.h does not exist in my project. I searched in the SDK files, but I couldn't find it.

I'm using a QN9080-001-M17, does the fsl_xcvr.h exists for QN?

I'm trying to change the advertising tx power in the wireless uart project, is it possible?

Regards,

Renato
