Question about the simpleBLEperipheral throughput

Hi,

I've just started with the througput demonstration in:

http://processors.wiki.ti.com/index.php/CC2540_Data_Throughput

I'm employing the TI sniffer.

My program is running with no problems and I can see the groups of 4 notifications.

Then, I extract a fragment of communication of 1 second, for example, from timestamp 17430097 to 17530096 (more or less 1000000 us = 1 second).

The number of packets within is from numbers 1133 - 1071 = 62. Taking into account the half of the packets are NOT notifications with sendData(), this gives more or less 30 packets x 20 bytes within a second.... 600 bytes / second = 0.6kbps.

What am I doing wrong? Should not this be around 6kbps as indicated in the link? I can see connection events each 8000us = 8ms, as indicated in the code provided for this test, in the same link. Am I misunderstanding something?

Let me know! :) Thanks!

    I thought I had solved this but no.

    Any hint about what I'm observing?

    Thanks.

    Solved

    The final interval should be around 18430097, not around 17530097. Till 17530097 there are only 100ms :)

    Bye.
