CC3351: WIFI MAC address and BLE MAC address

Fabio Gou

Part Number: CC3351

Tool/software:

1. Do I need to write the MAC address of WIFI and BLE separately in CC3351? Can the same MAC address be used？

2. Whether CC3351 support a runtime configurable WI-FI MAC address?

3. Whether CC3351 be able to automatically detect the country in which the appliance is, in order to configure the allowed Wi-Fi country settings using the Linux regulatory database?

Hi Fabio,

It is not required to write your own MAC address, but can do so optionally. You can create 'NVS' file that contains the base MAC address that will be used. You can read more about this in the CC33xx Linux SDK. The same address should NOT be used for both WiFi and BLE.

Yes, you can change the WiFi MAC address with ifconfig command.

You can configure the country code by writing the country in wpa_supplicant.conf.

You can configure the country code by writing the country in wpa_supplicant.conf.

Just be forewarned. If you are going to ship into the U.S. (and presumably a number of other countries) you must abide by the configuration control requirements that say this cannot be configured by the end user, professional installer etc. Devices sold in the U.S. must be locked down to U.S. only and not modifiable. You will have to attest to this when you go through the regulatory certification process...

One more question:

WLAN throughput on IP layer>=50Mbps.

Whether CC3351 could meet this requirements?

Hi Fabio,

Yes, you can reach that throughput level with CC3351.
