Gosh, I can't believe no one ever answered you here. Did you get an answer? My guess is that this would not be possible with an inexpensive controller like the GameSir T1d, already designed for the Tello exclusively. Also, I don't think the Bluetooth frequency at such low power, intended basically for just a few feet, would interfere with the WiFi longer range frequencies, in this case only 2.4 Ghz. 5.8 is only in bigger drones.
This has been a very helpful post, thank you to all who have contributed. i can't tell you how many frustrating hours I've spent searching for answers on what controller to get.
I'm getting this for my son and want to be sure that what is under the Christmas tree actually works so he's not disappointed.
Sounds like the preferred method is the T1s with an OTG cable. Now I have read that Android phones will need to be rooted; is this actually the case? I have an old Nexus 5 that I was going to give him with it (wish i didn't need the phone at all) but want to make sure all this works...

I can't say with certainty what is the earliest version that supports OTG
Thanks for the answer JasonMC.
