EMS not communicating with Flightbox Pro

I have installed the Flightbox Pro, ADC, EMS and all the accompanying sensors to monitor my engine parameters. Everything but the Ems and its sensors are being displayed on my tablet. When I go into the setting it shows that there’s no data from the Ems. Everything is hooked up correctly as I’ve ready the installation manual and followed the sensor installation process. Has anyone ran into this problem? Thank you
