Text send via HC-05 is broken up by first character on the receiving end?
I did something similar (multiBT) using HC-05 and PC BT, with the same App.
Results: all the incoming data from the PC_BT to the phone are right, but with the HC-05 sometimes is chunked as @deostrol show. I think is a bug with the HC-05 firmware.
To correct this, I've implemented StartBegin and StopFinish character in the received string before use.
