What's Peer-to-Peer mode speed (Throughput) ?

Contributor II



I am running separately two NfcrdlibEx3_NFCForum examples on two PN7462 boards.


First board Server (NfcrdlibEx3_NFCForum.h):


      #define ACTIVE_MODE

      #define TARGET_MODE

      #define SNEP_SERVER


Second board Client (NfcrdlibEx3_NFCForum.h):


     #define SNEP_CLIENT

     #define INITIATOR_MODE

     #define ACTIVE_MODE


I want to count what's the throughput(speed) of data send from client to server with PUT. To count that I am using timer, which I turn after phnpSnep_Put was successful and start counting how many times Put request was successful in 5 seconds.


Timer functions:


phhalTimer_RequestTimer(E_TUNIT_SECS, &Counter);

phhalTimer_Configure(Counter, 5, %phTimer_CallBack);

phhalTimer_Start(Counter, E_TIMER_SINGLE_SHOT);


After 5seconds I get that around 30times it was successful and I am sending 8bytes data, which is really low.


(30times*8bytessend)/5seconds = 48bytes/s


NFC Bit rates:


            106kbits/s  ----->   13250bytes/s 

            212kbits/s ----->    26500bytes/s

            424kbits/s ----->    53000bytes/s





I also tried to count data throughput by setting the timer for 10seconds and count how much successful PUT request was send from client to server. And I make a table of the results


Data rate / Data size106 kbits/s212 kbits/s424 kbits/s
8 Bytes45.6 Bps46.4 Bps48 Bps
16 Bytes92.8 Bps92.8 Bps 96 Bps

Thank you in advanced, the code for counting and setting the timer of client you can find in attachment.

I want to know the same details. What could be the throughput in peer-to-peer mode data transfer using two NXP PNE7462C EVK kits using the NFC Forum example of the SDK(v5.22.01)? What could be throughput with different RF data rates?
