DA1468x

What is the maximum time for which the interrupts are disabled in the BLE stack?

I am using DA14681 dev kit (PRO) and using pxp_reporter example. I modified the example to add a hw_timer0 and in the timer ISR, I simply toggle a I/O line and looking at the period on o-scope. The timer is configured to interrupt every 500 micro-secs, but I am seeing >200 micro-secs of jitter on o-scope. However, when I disable the pxp_reporter task (commented out the creation of this task), this jitter reduces (~ 20 micro-secs).

I am using DA14681 devkit PRO board and pxp_reporter example. I want to add hw_timer0 to this project and want to toggle an i/O line in timer0_isr. I noticed that this toggle is synchronous to the blue LED flashing (fast or slow advertising) on the board.

Where can I find the source code for this blinking LED?

Is hw_timer0 being used anywhere in this example? How do I know what peripherals are being used by the different sdk examples? From the forums, I realize that timer1 is used by the FreeRTOS. Can you list different peripherals that are used by this example?
