Hi,
I have integrated ble_uart_app with timer example provided in "SDK 17.0.2".
When I run the program the timer timeout immediately by calling "timer_led_event_handler" instead of waiting for 5sec. I am not sure if I am missing anything here.
const nrf_drv_timer_t TIMER_LED = NRF_DRV_TIMER_INSTANCE(1);
void timer_led_event_handler(nrf_timer_event_t event_type, void* p_context)
{
printf("\r\n Timer End");
nrf_gpio_pin_clear(ARDUINO_0_PIN);
nrf_drv_timer_disable(&TIMER_LED);
}
/**@brief Application main function.
*/
int main(void)
{
bool erase_bonds;
// Initialize.
uart_init();
log_init();
timers_init();
buttons_leds_init(&erase_bonds);
power_management_init();
ble_stack_init();
gap_params_init();
gatt_init();
services_init();
advertising_init();
conn_params_init();
// Start execution.
printf("\r\nUART started.\r\n");
NRF_LOG_INFO("Debug logging for UART over RTT started.");
advertising_start();
uint32_t time_ms = 5000;
uint32_t time_ticks;
uint32_t err_code = NRF_SUCCESS;
nrf_gpio_cfg_output(ARDUINO_0_PIN);
//Configure TIMER_LED for generating simple light effect - leds on board will invert his state one after the other.
nrf_drv_timer_config_t timer_cfg = NRF_DRV_TIMER_DEFAULT_CONFIG;
err_code = nrf_drv_timer_init(&TIMER_LED, &timer_cfg, timer_led_event_handler);
APP_ERROR_CHECK(err_code);
time_ticks = nrf_drv_timer_ms_to_ticks(&TIMER_LED, time_ms);
nrf_drv_timer_extended_compare(
&TIMER_LED, NRF_TIMER_CC_CHANNEL1, time_ticks, NRF_TIMER_SHORT_COMPARE1_CLEAR_MASK, true);
nrf_drv_timer_enable(&TIMER_LED);
printf("\r\n Timer Start");
nrf_gpio_pin_set(ARDUINO_0_PIN);
// Enter main loop.
for (;;)
{
idle_state_handle();
}
}
Regards
Siva
