I used nRF52832 , SDK 15.0 ,S132，FreeRTOS 10(From "ble_app_hrs_freertos")。
My work needs to be realized three functions:
(1) From "ble_uart_c" method receive another BLE send data;
(2) Use the FreeRTOS resolved the multi-task;
(3) From SPI to receive the external sensor data ( 200Hz ,by interrupt).
First I transplanted the FreeRTOS from "ble_app_hrs_freertos" sample, and used to "ble_app_uart_c " sample , it worked well, it's ok.
Second I added the external sensor interrupt and event-Handle, and it also work well;
Finally ,I put them together , the problem is , the "ble_uart_c" will connects, disconnects, and reconnects frequently, the connected time is more than ten seconds.
I think maybe is the Priority problem,but I set the "#define configMAX_PRIORITIES ( 5 )" , and set the "ble_uart_c" 4; and set the "#define taskPRIO_RxData 3 "(receive the sensor data function task), and it's not work, I am very confused and worried.
Can you help me ,thanks very much ,I will be waiting!
// the INT of Sensor
static void vINTHandler(nrfx_gpiote_pin_t pin, nrf_gpiote_polarity_t actio)
{
BaseType_t xHigherPriorityTaskWoken = pdFALSE;
G_Counter++;
xTaskNotifyFromISR(xTaskHandle_RxData_MPU9255,
G_Counter,
eSetValueWithOverwrite,
&xHigherPriorityTaskWoken);
portYIELD_FROM_ISR(xHigherPriorityTaskWoken);
}
//the task of Rx Sensor data
static void vTask_RxData_MPU9255(void *pvParameters)
{
uint8_t error_temp = 0;
while(1)
{
xTaskNotifyWait(0x00000000,
0xFFFFFFFF,
NULL,
portMAX_DELAY);
memcpy(G_Data+6,&G_MicroSecond,2);
memcpy(G_Data+2,&G_WeekSecond,4);
memcpy(G_Data+8,&G_Counter,4);
}
}
They both work very well separately, but when they work together they have problems, they seem to interfere with each other.
