I am facing issue with BLE advertisement in nRF52833. The board I am using is rayBeacon: nRF52 on-the-go Development Kit. The code I am using is example code from nRF Academy.
#include <zephyr/kernel.h>
#include <zephyr/device.h>
#include <zephyr/devicetree.h>
#include <zephyr/logging/log.h>
#include <zephyr/drivers/gpio.h>
#include <zephyr/bluetooth/gap.h>
#include <zephyr/bluetooth/bluetooth.h>
/* Log Module Registration */
LOG_MODULE_REGISTER(BLE_LOG, LOG_LEVEL_DBG);
/* Sleep Time */
#define SLEEP_TIME_MS 1000
/* The devicetree node identifier for the "led0" alias. */
#define LED0_NODE DT_ALIAS(led0)
static const struct gpio_dt_spec led = GPIO_DT_SPEC_GET(LED0_NODE, gpios);
/* Set Device Name */
#define DEVICE_NAME CONFIG_BT_DEVICE_NAME
#define DEVICE_NAME_LEN (sizeof(DEVICE_NAME) - 1)
/* Advertising Packet */
static const struct bt_data ad[] = {
BT_DATA_BYTES(BT_DATA_FLAGS, BT_LE_AD_NO_BREDR),
BT_DATA(BT_DATA_NAME_COMPLETE, DEVICE_NAME, DEVICE_NAME_LEN),
};
/* URI */
static unsigned char url_data[] = {
0x17, '/', '/', 'w', 'w', 'w', '.', 'u', 's', 't', '.', 'c', 'o', 'm'};
/* Scan Response Packet*/
static const struct bt_data sd[] = {
BT_DATA(BT_DATA_URI, url_data, sizeof(url_data)),
};
int main(void)
{
int err;
if (!gpio_is_ready_dt(&led))
{
return 0;
}
err = gpio_pin_configure_dt(&led, GPIO_OUTPUT_ACTIVE);
if (err < 0)
{
return 0;
}
err = bt_enable(NULL);
if (err)
{
LOG_ERR("Bluetooth init failed (err %d)\n", err);
return 0;
}
LOG_INF("Bluetooth initialized\n");
err = bt_le_adv_start(BT_LE_ADV_NCONN, ad, ARRAY_SIZE(ad),
sd, ARRAY_SIZE(sd));
if (err)
{
LOG_ERR("Advertising failed to start (err %d)\n", err);
return 0;
}
LOG_INF("Advertising successfully started\n");
for (;;)
{
gpio_pin_toggle_dt(&led);
k_sleep(K_MSEC(SLEEP_TIME_MS));
}
}
The error I am facing is nRF52833 is resetting continuously after the advertisement is started. The response in the terminal is
