Great! Happy to hear that you found the cause of the issue!

I have good news for you, OTA succeed by changing the parameter MIN_CONN_INTERVAL and MAX_CONN_INTERVAL. The original value is 15 and 30.Now the value is 100 and 200.However,the result is the speed of all the
OTA,no matter the IOS and Android,decreased. Now I tried to find the best value to balance the OTA.

I have checked the code step by step,found the program stop at the event as follows: static void on_dfu_evt(ble_dfu_t *p_dfu,ble_dfu_evt_t *p_evt)

{ // // }

It means that there is no dfu_event to generate. The dfu_event is defined as follows: static void services_init(void)

{ uint32_t err_code; ble_dfu_init_t dfu_init_obj; memset(&dfu_init_obj,0,sizeof(dfu_init_obj));

dfu_init_obj.revision = DFU_REVISION; dfu_init_obj.evt_handler = on_dfu_evt; dfu_init_obj_error_handler = service_error_handler; ble_dfu_init(&m_dfu,&dfu_init_obj); }

What happened to the program?

Decreasing it to 10 has no effect on OTA,but I change it to 768,sometimes the rate of OTA progress can reach to 7%.

Hi again, could you try to decrease it to 10, i.e.

#define SCHED_QUEUE_SIZE                10

and see if that helps.

I have tried as you say,but it failed. What circumstance,it will lead the result of m_queue_start_index = m_queue_end_index?

Could you try increasing the SCHED_QUEUE_SIZE define in main.c to a higher value, e.g. 30

#define SCHED_QUEUE_SIZE                30
