Thanks, I'll check that out. Separate from that, it makes me smile when I hear "search on the internet" when that's exactly what this here is. Just laughing at the irony of it. ?You may have go to mirror site like "apkpure" and search for some old DJI GO apps. They will have some that go way back. Sorry but I am not sure of the latest app that will work with the BT-200. Search the internet you may find the answer. You will have to side-load the app.
