You need a printer cable to connect to the back of the Katana.
And an OTG cable to connect your phone to the printer cable
I have the regular bike - I believe it's Gen 3, since I got it in Nov. Mine has a regular USB port. But you could always get a converter like this: https://smile.amazon.com/UGREEN-Adapter-Samsung-Controller-Smartphone/dp/B00LN3LQKQ/ref=redir_mobile_desktop?ie=UTF8&aaxitk=oWy27Rgp-ZPTRv3TU7IZhA&hsa_cr_id=5924767640601&pd_rd_plhdr=t&pd_rd_r=c39353b8-ef21-489b-96c9-a9cdb90cb20c&pd_rd_w=OB1ZA&pd_rd_wg=sWZs4&ref_=sbx_be_s_sparkle_td_asin_1_title&th=1
I added photos so you could see what mine looks like from the back: https://imgur.com/a/q8zT2AM
You can! I did it with my Nexus 7 tablet (2013, but device shouldn't matter), and it works great.
First, I got this USB adapter to connect from my tablet to the wireless adapter.
Then I'm able to use this Alfa AWUS036NEH WiFi adapter, and it appears as wlan1.
Happy hacking!
