I have been trying to connect my 2560 with a hm-10 to the remotexy app but can't get it to connect as i keep receiving the "Error: Device not reply" message. I have used TX to pin 51 and RX to pin 50. I have attached my code below which was made by RemoteXY. Thanks in advance for your help!

/ RemoteXY select connection mode and include library
#define REMOTEXY_MODE__SOFTSERIAL
#include <SoftwareSerial.h>

#include <RemoteXY.h>

// RemoteXY connection settings
#define REMOTEXY_SERIAL_RX 50
#define REMOTEXY_SERIAL_TX 51
#define REMOTEXY_SERIAL_SPEED 9600

// RemoteXY configurate 
#pragma pack(push, 1)
