Hi All,
I would like to make bluetooth data collector with a serial line. There are max 16 bluetooth devices on the air where I need to collect data. There is a PC which continuosly polling this device by serial line. Maybe I need FreeRTOS to solve this problem. I found blinky and hrs emulator freertos version, and ble_central HRS application examples.
I use a PAC10040 board. The ble task is like this:
bool erase_bonds=false;
timers_init();
ble_stack_init();
peer_manager_init(erase_bonds);
if (erase_bonds == true)
NRF_LOG_INFO("Bonds erased!\r\n");
gatt_init();
db_discovery_init();
hrs_c_init();
bas_c_init();
scan_start();
for (;;)
{
while(pdFALSE==xSemaphoreTake(m_ble_event_ready, portMAX_DELAY))
;
intern_softdevice_events_execute();
}
}
and main function is like this:
ret_code_t err_code;
//bool erase_bonds;
timers_init();
err_code = nrf_drv_clock_init();
APP_ERROR_CHECK(err_code);
bsp_board_leds_init();
bsp_board_buttons_init();
m_ble_event_ready = xSemaphoreCreateBinary();
if (NULL == m_ble_event_ready)
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
err_code = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(err_code);
if (pdPASS != xTaskCreate(ble_stack_thread, "BLE", 256, NULL, 2, &m_ble_stack_thread))
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
if (pdPASS != xTaskCreate(logger_thread, "LOG", 256, NULL, 1, &m_logger_thread))
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
if (pdPASS != xTaskCreate(alive_thread, "ALV", 63, NULL, 1, &m_alive_thread))
APP_ERROR_HANDLER(NRF_ERROR_NO_MEM);
serial_init();
SCB->SCR |= SCB_SCR_SLEEPDEEP_Msk;
NRF_LOG_INFO("Starting system\r\n");
vTaskStartScheduler();
while (true)
;
serial_init starts a new task which is handle the serial port. Everything works well when I not started ble_thread. If I start ble_thread, there is no log messages, the tasks are run (I checked them with breakpoint), and there is no ble handling.
I use sdk nRF5_SDK_12.3.0_d7731ad. Logging works in RTT link.
I gave more heap (16384bytes) to freeRTOS in config, and I changed port_cmsis_systick.c as suggested devzone.nordicsemi.com/.../
Is there any documentaion for the init sequences under freertos?
thx Zamek
