The 6505 can't do SMBv2 or SMBv3
SMBv1 is now disabled on all current Operating systems due to the Wannacry thing a while back, I'm guessing your tablet never got that update.
This would leave you with 2 choices:
1. Enable SMBv1 on the PC
2. Enable FTP and use that instead.
I would pick option 2, although I admit option 1 is much simpler, but, it has a much higher security risk than 2 does, and 2 is less likely to get reset with every Windows security update.
