Hello, I am trying to run the ble_app_uart_c example that is part of the nRF5_SDK_13.1.0_7ca7556 on a custom board with nRF52832 using IAR. Hardware seems healthy, I succeeded to run LEDs and make them blink... I am having troubles with running the UART, however:
Initialization of UART is as follows:
const app_uart_comm_params_t comm_params =
{
.rx_pin_no = RX_PIN_NUMBER,
.tx_pin_no = TX_PIN_NUMBER,
.rts_pin_no = RTS_PIN_NUMBER,
.cts_pin_no = CTS_PIN_NUMBER,
.flow_control = APP_UART_FLOW_CONTROL_DISABLED,
.use_parity = false,
.baud_rate = UART_BAUDRATE_BAUDRATE_Baud115200
};
and also:
#define RX_PIN_NUMBER NULL
#define TX_PIN_NUMBER 7
#define CTS_PIN_NUMBER NULL
#define RTS_PIN_NUMBER NULL
#define HWFC false
After running uart_init(); passes with success (I have played with LEDs to get the result), however the debug lines
printf("BLE UART central example started.\r\n");
NRF_LOG_INFO("BLE UART central example started.\r\n");
do not produce any output on the TX pin.
Also, in the main loop I have the following:
for (;;)
{
//power_manage();
bsp_board_led_off(0);
bsp_board_led_on(1);
nrf_delay_ms(3000);
bsp_board_led_off(1);
bsp_board_led_on(0);
nrf_delay_ms(3000);
}
When the uart_init() is commented/disabled I can get the two LEDs blinking, if uart_init() is not commented and gets executed only one LEDs is always lit, which means the nrf_delay_ms is not executed properly.
Since I am dealing with ble_app_uart_c for first time, I am not quite sure where to search for the problem, any advice would be helpful.
