Updating is in real time while advertising. This is currently limited to 25 bytes and will return an error message of "Too much data" if that maximum has been exceeded. However, this does not check if the advertising payload length maximum has been exceeded so you may receive an error from bluetoothd that it "Failed to register advertisement" which means you need to reduce your manufacturer data length.

Usage
    # manufacturer [id] [data=xx xx ...]

  data

Set/Get advertise data.

This allows you to advertise data with a given type. You cannot use a registered data type value {1} with this command. For LE the advertising shows up in the primary advertisements.

If you set only the type of the data without any data (data 0x0c) this will cause a parse error when turning advertise on.

You can modify the advertising data while it is advertising.
