about maximum throughput of nrf51822

[Jones]

Hi,

I tried to use nrf51822 to update light intensity of 64 area to smartphone and then the smart phone will display those light intensity values in gray scale. I want make the data transmit as fast as it can. therefore I set the max connection interval to 10ms and min connection interval to 7.5ms. But the phone stop updates the data after a few second. I wonder is the bug from the ble or from the smart phone apps.

Also, I wonder how small the interval can be set.

Hi Jones,

Would be beneficial to get trace of radio communication (any BLE sniffer) to see what's happening and why connection breaks. Also note that while connection interval 7.5ms is great for throughput most of "mutli-applicational" centrals such as mobile phones don't like it. Normally both Android and iOS settle for connection intervals in the range of 40-50ms where they work OK (= are tested by mobile makers;).
