Hello,
I have been developing software on the ble_app_uart example in Segger Embedded Studio with sdk 17.0.2. The example has RTT enabled but I noticed when I try to use RTT in my modified version that no RTT shows up in the debugging window. I added various libraries and changed the config file, but did not remove anything or turn off anything in the config file from the example. I wasn't sure how to troubleshoot this and was wondering what potential problems might be interfering with RTT outputs in the debugging terminal. Here is my main() code, I can add more if necessary.
int main(void)
{
bool erase_bonds;
ret_code_t rc;
// Initialize.
twi_init();
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();
/* Register first to receive an event when initialization is complete. */
(void) fds_register(fds_evt_handler);
rc = fds_init();
APP_ERROR_CHECK(rc);
/* Wait for fds to initialize. */
wait_for_fds_ready();
// Start execution.
printf("\r\nUART started.\r\n");
//turn on LED3 while on and not in sleep mode
nrf_gpio_cfg_output(LED2);
nrf_gpio_pin_clear(LED2);
NRF_LOG_INFO("Debug logging for UART over RTT started.");
//button press waits for a button press event or times out and goes to sleep mode if no button press is received in 15 seconds
buttonPress();
nrf_delay_ms(100);
advertising_start();
//advertise for 15 seconds then try to send the data
nrf_delay_ms(5000);
//SendTime sends the entire memory, should add a condition to make sure that it's connected to BLE, potentially only send new entries etc.
SendTime();
//wait 5 seconds after sending the data before entering sleep mode, just here to give time to read in devtools for debugging
nrf_delay_ms(5000);
sleep_mode_enter_wakeup_enabled();
// Enter main loop.
for (;;)
{
idle_state_handle();
}
}
