Bluetooth is too slow IMHO, slow below usability bar, and I am afraid that you would not be rewarded appropriately for the amount of effort you spend to enable it.
On the other hand you can try wifi instead, it has it’s own problems, but at least you would have decent connection speed.
Also FalkTX had mentioned that there would be wifi AP mode for MOD devices in next releases Android phone with USB cable on the Dwarf - #15 by falkTX
Therefore I perceive wifi approach to be much more promising.
