I chose "task bar" at the beginning, then clicked on the "numb" with dots in the lower left corner -> settings -> connected devices > connection preferences, then pair new devices -> pairing com-dex 410. I guess it's a very bad downside for my goal because the only way to set comdex up is via its app but if I can't download it during a live android session it will be useless to pair bt and comdex I've got that huawei and it works properly on my ubuntu but android coulnd't find it in that live session. As soon as os started it began to search wifi. Let me tell you in details what it happened: Anyway I guess BT dongle worked and was paired to the comdex device but my huawei wifi dongle wasn't recognize by the os. It was my very first time with android os because I've never got a smartphone so honestly I'm not so sure about what it happened, I mean what worked and what didn't.

I put android x86 in a pendrive with rufus and I ran it live.
