Hello,
Is it possible to do the following in MTB?
Target: CYW43438
1) Wi-Fi MAC address
The following describes how to change the MAC address in WICED.
Wifi mac address modification in WICED
Like "CUSTOM MODE" of this Forum, I want to change the MAC address with Modus.
However, I can't find a similar API for the WHD API.
Does the current version of MTB support it?
2) BT Address/Public device Address
I want to change the BD address as well as the Wi-Fi MAC address.
Is there an API to change the BD address with the HCI command?
Best regards,
Takahashi

Hello KeTa_1341526
1. The host_get_mac_address() ultimately used the wwd_wifi_set_mac_address(). The equivalent of this can be found at whd_wifi.c with the API being whd_wifi_set_mac_address()
2. There is no API as such to change the BT MAC of combo devices, however you can use vendor specific HCI commands to achieve this as shown below.
Thanks

Hello MuraliR_36,
Thank you for your reply.
About 2, I found the following Forum.
Configuring the Bluetooth device address in CYW20706
Is it possible to use [3. Using the Factory_Commit_BD_ADDR VSC] of this?
Is it possible to issue a Vendor specific command by using "wiced_bt_dev_vendor_specific_command"?
Best regards,
Takahashi

Yes it is possible to use wiced_bt_dev_vendor_specific_command() to send the vendor specific command.
Also, to make it clear, the blog post you mentioned is specific for CYW20706, not the combo device like 43438.

You say I can use wiced_bt_dev_vendor_specific_command on CYW43438, right?
It was also described in the API document for the WICED version of the Combo device, so I think that it can also be used with the Combo device.

Hi Sheetal,
I am also facing similar type of issue and had initiated mail thread in below link:
Configuring unique BD address for client device in CYBT-483039-EVAL
we have used the wmbt command line to set the BD address. Although we have put the BT_DEVICE_ADDRESS=FFFFFFFFFFFF in make target, but while setting factory commit VSC command, it is failed to execute and showing below message:
"Failed execute_factory_commit_bd_addr. Make sure the BD ADDR was programmed to all FFs before using this command!"
Please check in steps that we followed for your reference and please suggest if we are doing anything wrong.
