Hello,
use a 1m standard USB-A to micro USB cable for the
GameSir T1s. The housing of the micro USB plug has to be narrow so that it fits into the
GameSir T1s socket, for example
this one.
Then use this
OTG adapter to connect to an Android smartphone with a micro OSB socket.
Or use
this adapter to connect to an Android smartphone with a USB-C socket.
I've been using this combination for years without any problems, but only with the
Tello-FPV app.
With an Apple device I have not been able to establish a cable connection.
