app_timer_stop return 0x04(NO MEM) error

[lyrics]

Hi, all..

An error occurs as soon as it connect and disconnect through advertising. Timer interrupt is currently running on the main function..

and then I found error meaing.. below.. 

 

 * @retval     NRF_ERROR_NO_MEM          If the timer operations queue was full.
 */
ret_code_t app_timer_stop(app_timer_id_t timer_id);

so 'timer operation queue was full' is the reason..

then where should I check? 

BR,

Hi, you can try to increase APP_TIMER_CONFIG_OP_QUEUE_SIZE in sdk_config.h.

You might also consider checking how often you call app_timer library functions, maybe you have frequent unnecessary calls to the library !

APP_TIMER_CONFIG_OP_QUEUE_SIZE is set to 10..

so I increase to 20, but still same error. Do I have to set a higher value?..

My project is based 'ble_app_uart.c'.. and I added scan module / two timer interrupt..(ms and ns)

Also it works first connection!

For a specific app I had to increase above 100 because I needed repeated calls to app_timer_start and app_timer_stop, that fixed the issue

Best regards,

My project seems to be a different matter. The error is still not fixed..

Hi,

 What timer instance are you using? Are you using  ble_app_uart_c i.e the central NUS example? If you are then it already has the scanner module enabled. Can you share your code?
