Yes the application is as shown in the photo.

Mic - Preamp - Delta Sigma Modulator - Decimation Filter - Udp transmitter ONLY with 512 bytes payload and transmitting 305 pps ( 3.3ms interframe gap ).

Everything works great as i checked but only the PC doesnt receive packets.

I scope the Tx pins to trace the packets and i did.

Maybe i did a mistake on the Pulse RJ45 and connecting only a cap 100nF to the pin_4 of its transformer.

So you are telling me that i have to add also a RC filter? 100Ohm and a cap(value?)?

The project is done by me and refugee in IPL in Portugal as Erasmus Students.
