Android Question Bluetooth and wifi

Hi! im new to this enviroment, yesterday i started testing the compiler (i purchased the last version) and i noted something.

If i use the b4A bridge via wifi, when i start testing a bluetooth app, the compiler disconnects from the bridge... it seems tha is a hardware problem on my tablet... is there any way to test my app using a cable connection?

Sorry if im asking a stupid question, im new to b4A.

thanks!
