N32WB03是一款集成了蓝牙低功耗(BLE)功能的芯片,它使用Nordic nRF52系列的SoC,可以在低功耗模式下提供高效的无线通信。下面是一个基于N32WB03实现低功耗蓝牙代码的简单示例:
```
#include "nrf.h"
#include "nrf_ble_gatt.h"
#include "nrf_pwr_mgmt.h"
#include "nrf_sdh_ble.h"
#include "nrf_sdh.h"
#define DEVICE_NAME "MyDevice"
#define APP_BLE_OBSERVER_PRIO 3
#define APP_BLE_CONN_CFG_TAG 1
static uint16_t m_conn_handle = BLE_CONN_HANDLE_INVALID;
static void ble_evt_handler(ble_evt_t const * p_ble_evt, void * p_context)
{
switch (p_ble_evt->header.evt_id)
{
case BLE_GAP_EVT_CONNECTED:
m_conn_handle = p_ble_evt->evt.gap_evt.conn_handle;
break;
case BLE_GAP_EVT_DISCONNECTED:
m_conn_handle = BLE_CONN_HANDLE_INVALID;
break;
default:
// No implementation needed.
break;
}
}
NRF_SDH_BLE_OBSERVER(m_ble_observer, APP_BLE_OBSERVER_PRIO, ble_evt_handler, NULL);
int main(void)
{
ret_code_t err_code;
// Initialize the SoftDevice handler module.
err_code = nrf_sdh_enable_request();
APP_ERROR_CHECK(err_code);
// Configure the BLE stack using the default settings.
// Fetch the BLE stack instance.
ble_stack_init();
// Initialize the GATT library.
err_code = nrf_ble_gatt_init();
APP_ERROR_CHECK(err_code);
// Initialize the SoftDevice power management module.
err_code = nrf_pwr_mgmt_init();
APP_ERROR_CHECK(err_code);
// Set the device name.
err_code = sd_ble_gap_device_name_set(&APP_BLE_CONN_CFG_TAG, (const uint8_t *)DEVICE_NAME, strlen(DEVICE_NAME));
APP_ERROR_CHECK(err_code);
// Start advertising.
err_code = sd_ble_gap_adv_start(&APP_BLE_CONN_CFG_TAG, NULL);
APP_ERROR_CHECK(err_code);
// Enter main loop.
while (1)
{
// Sleep until next event.
nrf_pwr_mgmt_run();
}
}
```
这个示例代码使用了Nordic SoftDevice Handler(SDH)和SoftDevice Ble Stack来配置和管理蓝牙低功耗通信,同时使用了Nordic BLE GATT库来实现Generic Attribute Profile(GATT)。在main函数中,代码首先启用了SDH并初始化了BLE stack、GATT库和Power Management模块。然后设置了设备名称并启动了广告,最后进入主循环并休眠等待下一个事件的发生。
请注意,这只是一个简单的示例,实际应用中可能需要添加更多的代码来处理蓝牙低功耗通信的各种情况。
