I think you mean BCM20736.
Note that AlterIntelHex.exe is an internal tool, so I am not sure how it was obtained, but it is not supported here on the forum as it is undocumented and could easily brick the firmware if used incorrectly.
The command line tools should be used to change the BD_ADDR: Programming the TAG2/TAG3 Board using command line tools
Yes You are right. it is BCM20736.
Thanks for your comments. So you mean BD_ADDR is 6 Bytes data is nothing but MAC ID. Correct me if I'm wrong.
Also can you please provide the link to download "WICED SMART SDK 2.2" tool. Thanks.
A Bluetooth device uses a unique 6-Byte/48-bit address, commonly abbreviated BD_ADDR. The most-significant half (24 bits) of the address is an organization unique identifier (OUI), which identifies the manufacturer. The lower 24-bits are the unique portion of the address.
Here's two more threads that are relevant:
The chipload tools I believe you are referring to are attached to the first link/thread I referenced and the one above.
