Nice catch and thanks for sharing.

So it sounds like you created an RFID reader that communicates over a network!

Sounds like the same project I was working on!

Although I ended up never finished my project, I did order a couple of these chips to play with.

 

SMT PoE solution with integrated DC-DC converter. 3.3V or 5V or 12V. 12 pin SMD

I was planning on powering my card reader this way.

SOLVED!

Sorry do not waste time in found any solution it was simply a GC problem. During my tests I simply wrote this:

        private static void StartRFID()        {            var idReader = new RFIDReader(SerialPorts.COM1, Pins.GPIO_PIN_D4);            idReader.RfidEvent += new RFIDReader.RfidEventDelegate(_idReader_RfidEvent);            idReader.Start();        }

So the GC during "collection" disposed my idReader variable. Right code is:

        private static void StartRFID()        {            idReader = new RFIDReader(SerialPorts.COM1, Pins.GPIO_PIN_D4);            idReader.RfidEvent += new RFIDReader.RfidEventDelegate(_idReader_RfidEvent);            idReader.Start();        }

Where the idReader is global scope declared.

WOW,

it seems we are working on (exactly) the same project. I'm looking for a similar PoE chip. We are testing STM PM8803 http://www.st.com/st...er/flpm8803.pdf

 

I hope we can exchange the project (Hardware and Software) when finished.

 

keep in touch
