Is there a way for me to specify which 5G channel to use?

Thanks,

Hi Bill,

The CC3235x devices support configuring a country code/regulatory domain via the SimpleLink Host Driver API. Please refer to section 4.3.2.2 Set General STA Parameters of the NWP guide:

There is also an option for setting a mask to specify which 5G channels should be used during scan with the sl_WlanSet() function call.

Best Regards,

Thanks for the quick response Ben. This doesn't exactly answer my question though.

Our antenna is optimized for 5.8GHz and does not perform so well at 5.180GHz. I need to select a channel closer to the middle of the range and avoid using the lower channels (like channel 36).

Is there a way that I can specify which channel to use?

Thanks,

Bill

Hi Bill,

What role will your system be operating in? Why did you choose the antenna that is optimized for 5.8GHz?

The role for this node is station. The why isn't relevant but it is a custom antenna, a special application over very short distance.

Hi Bill,

If the node is a Wi-Fi STA, the channel will be set based on the AP that the device connects to.

Hi Bill,

Channel number depends on set channel on your infrastructure access point. Client node cannot do anything with that.

Releasing product which depends on channel number set at access point is best way how to have big interoperability issues any many unsatisfied customers.
