hello  all

i am now being tested for CSR1010 and ATmega by uart communication.

CSR sends data periodically (2 second) that make on/off led in Atmega

before association this is normally operated. 

but after association Atmega led on/off are irregular 

i gave the data clearly at 2 second intervals but much slower cycle light up. (approximately 4 seconds?)

what happen to this??

Are you asking why the LED on ATmega do not flash as expected ? Is the UART is sensing data every 2 sec? My guess is that after CSR1010 association with the phone you do not send the data to UART at the same rate. The use of ATmega when you have CSR1010 is west of money and space on PCB. CSR1010 with its 2 inner CPUs can do all.

How are you timing 2 seconds? I would expect CSR1010 timers (TimerCreate etc) to be very accurate.
