nrf51-ble-app-lbs throughput test

Hi,

I am using the Evaluation Kit, and I have tried to send some data between the Developoment Dongle (PCA10000) to the Evaluation Kit board (PCA10001). As the Development Dongle supports only one packet per connection interval, the theoretical maximum throughput is:

( 1 packet x 20 B ) / 0.0075 = 2667 B/s

And when I try to send data from the dongle to the evaluation kit board I manage to reach this throughput (thanks to Ole Morten) when using the nrf uart example you provided.(previous question)

But when I try the nrf51-ble-app-lbs throughput test I can't reach the same level of throughput (about 1 kB/s). I thought that it should be the same?

The code setup:

#define MIN_CONN_INTERVAL MSEC_TO_UNITS(7.5, UNIT_1_25_MS)            
#define MAX_CONN_INTERVAL MSEC_TO_UNITS(40, UNIT_1_25_MS)

I have tried to find something that could slow the throughput down, but do not find anything...
