NO MEMORY ERROR FOR "app_sched_event_put" FUNCTION

[NANDHU]

HI

  In our application we are using  "app_sched_event_put" function but its showing [NRF_ERROR_NO_MEM]  when i debugged  it please look the screen shot.

The sdk we are using is   "nRF5_SDK_15.3.0_59ac345"

What are the changes i want do to slove these issue.

That means that you're pushing way too many events to the scheduler queue. Check where are you pushing events to the queue and/or increase the queue size of the scheduler.

Inside a gpio handler . Actually we are configuring a 2d sensor with nrf52832 through spi . These 2d sensor contains a motion pin .when ever there is a motion occurred these pin state will change from high to low(normally motion pin is high).

we connected the motion pin to nrf52832  P0.15 pin and  also these is configured to generate an interrupt whenever its state become high to low .when these interrupt generate the code execution will enter to the gpio handler ,Inside these gpio handler we are calling the   app_sched_event_put     function .

 How can i increase  the queue size of the scheduler? what is the size i want to give?

That's your problem, you shouldn't just push to the queue whenever. Regardless of the size of the queue, if you keep pushing to the queue faster than you can service those events, you will fill the queue. You have to figure out a way to manage the pushing side, not the size of the queue.

Andy ,

 I already tried a  way to manage the pushing .i.e when ever the code execution enter to that gpio handler  i  disabled the gpio interrupt and after all the  process done (app_sched_event_put)  i enabled the gpio interrupt . Now that issue is not happening.

Is there any issue with these change in  gpio handler?

[Andy]

I don't know, is there? You are the one testing.

Nothing man . thanks for your reply .
