sending above 8 hz reboots arduino uno with readbearlab shield v1.1

[Koen]

Hi,

I'm using an arduino uno with a readbearlab shield with v1.1 to send sensor data to a android phone. Using a timer interrupt I try to send data every 0.1 sec (10hz) to the phone.

This works for about 90 packets and then the arduino crashes and reboots

Can anyone tell me why? Can this be improved by using more pipes? I currently use only one...

Can anyone also tell me where data-credits are used for. Why I have credits 2 on the start and they sometimes increase?

Thanks!

I found the cause of the problem, at frequencies above 8HZ the memory usage increases and when the arduino runs out of sram, it reboots.

Does anyone have an idea what is causing the increased memory usage at higher frequencies?
