Hallo Benny!

 BP> usb ?

bluetooth.

 BP> i have already cables and wireless :)

All the ones I have right now are cabled, usb and ps2.  None of them will work
for this particular tablet.

While I was waiting I did manage to port some of the fidonet bash scripts to
termux.  I still need to troubleshoot and will probably wait for the bluetooth
keyboard to arrive which I had to order since local shops are closed. 
Hopefully it won't be too long.

Het leven is goed,
Maurice
