If you can solder in a normally open push button switch to two of the pins on the board as linked below, that will give you a program button and then you can do the bluetooth reset by pressing the new button 2 times real fast, a couple lights should flash together, then you press the button again 3 times real fast, and the board resets - you will likely be able to pair via bluetooth again - I assume by whatever method you know from doing it with a t-beam with out a screen.
