What are the Vendor commands used by DFU? #439

Ask the question

I am investigating the btsnoop_hci.log file generated by Android using wireshark. Works great.

I see a lot of Vendor commands such as: Sent Vendor Command 0x017D (opcode 0xFD7D) and Sent Vendor Command 0x01F1 (opcode 0xFDF1)

Questions: Do you have any documentation about what the opcodes and vendor commands mean? Specifically, 0x01F1 seems important, what does it do?

How do I understand what is happening in wireshark during a firmware update?

I have included some of the btsnoop_hci.log so you can see what I am looking at.

Sorry, no idea. This is a 'vendor" command, so it may depend on the manufacturer of the chip in your phone and perhaps may differ from phone to phone. You may check what's the manufacturer of the chip in your device, usually for phones they combine Bluetooth, Wi-Fi, etc in one, and check the documentation, if it's available.
