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

[gytiskazlauskas]

Hello,

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_Init();

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 size	106 kbits/s	212 kbits/s	424 kbits/s
8 Bytes	45.6 Bps	46.4 Bps	48 Bps
16 Bytes	92.8 Bps	92.8 Bps	96 Bps
64 Bytes	364.8 Bps	364.8 Bps	384 Bps
128 Bytes	704 Bps	716.8 Bps	755.2 Bps
256 Bytes	819.2 Bps	844.8 Bps	870.4 Bps
512 Bytes	1.485 kBps	1.587 kBps	1.6896 kBps
1024 Bytes	2.56 kBps	2.867 kBps	3.174 kBps

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

Hi,

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?
