Hi @ all!

I'm using a SN8000x with the SDK 3.0.1 and try to change the Tx-Power.

I found the function "wwd_wifi_set_tx_power()" and tried with '0' and '31' with the following assumption:

- 0 means 0dBm and the sending is off (or very low)

- 31 means 31dBm and is the maximum output of this module

- Returning WWD_SUCCESS means the setting is used now

Now I configured the SN8000x as AoftAP an joined this network with a laptop.

With a tool on the laptop I read out the RSSI of the SoftAP-Frames.

I changed the Tx-Power.

The seen RSSI with a distance abaut 10m is always abaut -60dB (jitter about +- 5dB).

=> I wonder why I can't see any changes of the SoftAP signal.

=> Is there any automatism active, which restore/change the Tx-Power?

(I have seen When using wiced_wifi_set_tx_power() function, I think that tx power is not changed, but there was no answer)

Can you perform the same test using our manufacturing test tool and let me know he results?

The document is found in the SDK directory "doc" and is called:  WICED-MFG202-R.pdf

To set the transmit power to +15dBm, use:

>wl –-serial 99 txpwr1 –d 15
