  2. You will need 2 pcs. One that connects to the MMDVM board that will send data. The other HC-05 (or HC-12) will connect to the display and will receive the data. Only 3 wire connection is needed for one way data transfer. The 4th wire is not used since there is no current two way application to do anything on the screen and have it change any function on the MMDVM. Please look at my blog where I first expimented with wireless display months ago. http://notebook.hvdn.org/2018/08/wireless-nextion-display-you-say.html
