XeThru Respiration Sensor Not Receiving Data

Hey all, I recently started playing with Novelda's XeThru X4M200 respiration sensor and I'm having trouble receiving any data. I'm using the example code provided in the documentation and following the circuit diagram shown in their guide however when I run it, it only prints "received:". The sensor works perfectly with the XeThru explorer software. I would really appreciate if anyone had thoughts or has had similar issues using this sensor, thanks a lot in advance!

No link to the used hardware, no code, no wiring diagram. Did you really read the sticky post at the top of the topic ("How to use this forum")?
