本章介绍对tkl_nbiot_ril.c的接口相关适配

  • Code: Select all

      /**
  * @brief ril驱动初始化
  * 
  * @param[in] null
  *
  * @return OPRT_OK on success. Others on error, please refer to tuya_error_code.h
  */
OPERATE_RET tkl_nbiot_ril_init(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

    ril层驱动初始化，在这里可以初始化后续需要用到的互斥锁及相关的一些信息

  • Code: Select all

    /**
  * @brief 注册事件回调
  * 
  * @param[in] evt_cb ：注册的相关事件回调函数
  * @param[in] evt_id ：事件定义
  *
  * @return OPRT_OK on success. Others on error, please refer to tuya_error_code.h
  */
 OPERATE_RET tkl_nbiot_ril_register_event_callback(TKL_RIL_EVENT_SEND_T evt_cb, TKL_RIL_EVENT_ID_T *evt_id)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

    ril层相关事件回调注册，主要包括成功识别及未识别到sim卡，网络附着成功及网络断开，网络附着被基站拒绝等事件，具体事件类型参考枚举TKL_RIL_EVENT_ID_T。

  • Code: Select all

    /**
 * @brief 查询ril层网络附着状态（建议异步处理）
 * 
 * @param[in] null
 *
 * @return OPRT_OK on success. Others on error, please refer to tuya_error_code.h
 */
OPERATE_RET tkl_nbiot_ril_attach_event_inquire(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}
/**
 * @brief 查询ril层网络附着状态（建议异步处理）
 * 
 * @param[in] null
 *
 * @return OPRT_OK on success. Others on error, please refer to tuya_error_code.h
 */
OPERATE_RET tkl_nbiot_ril_attach_event_inquire(VOID)
{
    // --- BEGIN: user implements ---
    return OPRT_NOT_SUPPORTED;
    // --- END: user implements ---
}

    由于有些情况下平台侧不会主动上报基站附着成功事件，所以SDK需要主动查询是否已经成功附着上基站。建议不要做任何等待，立即返回，通过发送事件异步处理。

  • Code: Select all

    /**
 * @brief 获取当前设备是否识别到sim卡
 *
 * @return BOOL_T true: 识别到卡 false: 未识别到卡
 */
 BOOL_T tkl_nbiot_ril_is_sim_ready(VOID)
{
    // --- BEGIN: user implements ---
    return 0;
    // --- END: user implements ---
}

    由于有些情况下平台侧不会主动上报成功识别到SIM事件，所以SDK需要主动查询是否已经成功识别SIM。
