You make it sound so wonderful... libdivecomputer returns a char * and a size to us - which is different for different dive computers. Lovely.
So all we can do is store the size and base64 encode the binary data that we get.

Yeah, it's ugly, but it should make a huge difference in BLE download speed if I understand correctly what's going on.
