LibOV.ProtocolError: Checksum for response incorrect

[defencore]

When I try to sniff traffic between the Android and the DJI RC, I get an error:

Is this related to #13? Do you get similar issue when using ovextcap? The libopenvizsla unconditionally forces firmware download while ov_ftdi does not.
