Mesh Mac Address

[WindJ]

 How to change the Bluetooth Mesh broadcast address?

Use the sd_ble_gap_addr_set function to change the broadcast address of PB-GATT，But PB-ADV still hasn't changed.

Thanks！

Hi WindJ, 

The mesh stack doesn't use the softdevice for advertising bearer. To set the address for Bluetooth Mesh adv packet you should use advertiser_address_set() . It's the function inside advertiser.c

Hi Hung,

Is there a function that can be called to set the device's bluetooth address across all roles and PDUs?

I would like to set the MAC addresses on my devices to an IEEE-registered public device address. Right now the new MAC address is placed in the UICR->CUSTOMER registers (as suggested here: https://devzone.nordicsemi.com/f/nordic-q-a/20310/public-static-ble-address/79125#79125). And I want all BLE packets sent from the device to use this MAC address.

Thanks,

-Thomas

Hi Thomas, 
Please open a new case for your request. We would need to have more information about your application, if you doing mesh and/or BLE (proxy).
