Not directly. Canon Connect will transfer RAW files to iOS, but not android. Canon Connect, as you have discovered, can only transfer JPEG files.
The work around is using a Card Reader or an App like: "Camera Connect and Control". I have no knowledge of the capabilities and functionality of the App.
Please see list of supported cameras before installing

Also remember Wi-Fi and Bluetooth are the least reliable and slowest method of transferring files. I believe the adage is, "Just because it has it, doesn't mean you should use it."
