高通9X07模块QMI架构使用入门
QMI(Qualcomm Message Interface) 高通用来替代OneRPC/DM的协议，用来与modem通信。
本文是摸索高通QMI机制一点经验,重点解读了如果建立拨号连接，仅供参考。qmi详细使用参考：高通QMI协议
1. QMI协议常用组件
- DMS(设备管理Device Management)
提供查询设备信息功能
参考:qmi/device_management_service_v01.h - NAS(网络访问Network Access)
提供网络管理功能
参考:qmi/network_access_service_v01.h - WDS(数据连接)
参考:qmi/wireless_data_service_v01.h - UIM(管理User Identity Module)
提供查询UIM卡信息
参考:qmi/user_identity_module_v01.h - CTL(控制服务)
用户发起其他服务请求前，必须先申请 ClientID, 这个ID就是由控制服务分配的, 这个服务永远在线
参考:qmi/control_service_v01.h - 数据(拨号服务)
建立数据连接
参考:data/qualcomm_mobile_access_point_msgr_v01.h
每个服务模块都定义了 请求、响应、通知Indication, 请求分为同步和异步,其中异步请求的结果通过indication通知。
2. QMI举例
越来越多9X07模块被用于物联网，那么首要解决的问题即建立数据连接，所以本文使用QMI建立数据网络连接示意。
2.1 QMI初始化及释放
9X07模块提供了qcmap_msgr服务来进行拨号，通过与dsi_netctrl对比，qcmap_msgr接口更清晰，而且操作也简单。
AP侧使用QMI架构和modem通信初始化流程是固定的：
qcmap_msgr_get_service_object_v01查询服务对象 =>
qmi_client_notifier_init初始化client通知信息 =>
qmi_client_get_service_list查询支持的服务列表个数 =>
qmi_client_get_service_list查询支持的服务列表信息 =>
qmi_client_init使用其中一个服务信息初始化client
参考代码：
void qcmap_ppp_init(qcmap_ppp_t *self,client_status_ind_t client_cb_ind) {
qmi_idl_service_object_type qcmap_msgr_qmi_idl_service_object;
uint32_t num_services = , num_entries = ;
qmi_service_info info[];
qmi_client_error_type qmi_error, qmi_err_code = QMI_NO_ERR;
assert(self);
self->qcmap_msgr_enable = FALSE;
self->qmi_qcmap_msgr_handle = ;
self->mobile_ap_handle = ;
qcmap_msgr_qmi_idl_service_object = qcmap_msgr_get_service_object_v01;//when faild, add your trick for this~
if (qcmap_msgr_qmi_idl_service_object == NULL)
{
LOG("qcmap_msgr service object not available");
return;
}
qmi_error = qmi_client_notifier_init(qcmap_msgr_qmi_idl_service_object,
&self->qmi_qcmap_msgr_os_params,
&self->qmi_qcmap_msgr_notifier);
if (qmi_error < )
{
LOG("qmi_client_notifier_init(qcmap_msgr) returned %d", qmi_error);
return;
}
/* Check if the service is up, if not wait on a signal */
while()
{
qmi_error = qmi_client_get_service_list(qcmap_msgr_qmi_idl_service_object,
NULL,
NULL,
&num_services);
LOG("qmi_client_get_service_list: %d",qmi_error);
if(qmi_error == QMI_NO_ERR)
break;
/* wait for server to come up */
QMI_CCI_OS_SIGNAL_WAIT(&self->qmi_qcmap_msgr_os_params, );
}
num_entries = num_services;
LOG("qmi_client_get_service_list: num_e %d num_s %d", num_entries, num_services);
/* The server has come up, store the information in info variable */
qmi_error = qmi_client_get_service_list(qcmap_msgr_qmi_idl_service_object,
info,
&num_entries,
&num_services);
LOG("qmi_client_get_service_list: num_e %d num_s %d error %d", num_entries, num_services, qmi_error);
if (qmi_error != QMI_NO_ERR)
{
qmi_client_release(self->qmi_qcmap_msgr_notifier);
self->qmi_qcmap_msgr_notifier = NULL;
LOG("Can not get qcmap_msgr service list %d",
qmi_error);
return;
}
qmi_error = qmi_client_init(&info[],
qcmap_msgr_qmi_idl_service_object,
client_cb_ind,
NULL,
NULL,
&self->qmi_qcmap_msgr_handle);
LOG("qmi_client_init: %d", qmi_error);
if (qmi_error != QMI_NO_ERR)
{
qmi_client_release(self->qmi_qcmap_msgr_notifier);
self->qmi_qcmap_msgr_notifier = NULL;
LOG("Can not init qcmap_msgr client %d", qmi_error);
return;
}
}
对应释放过程比较简单，主要是释放client初始化信息:
static void qcmap_ppp_uninit(qcmap_ppp_t *self) {
qmi_client_error_type qmi_error;
assert(self);
qmi_error = qmi_client_release(self->qmi_qcmap_msgr_notifier);
self->qmi_qcmap_msgr_notifier = NULL;
if (qmi_error != QMI_NO_ERR)
{
LOG("Can not release client qcmap notifier %d",qmi_error);
}
qmi_error = qmi_client_release(self->qmi_qcmap_msgr_handle);
self->qmi_qcmap_msgr_handle = NULL;
if (qmi_error != QMI_NO_ERR)
{
LOG("Can not release client qcmap handle %d",qmi_error);
}
}

综上，基本用到的就这些接口了，比起直接使用高通提供的QCMAP_Client类接口，本文实现更原生、灵活，经过验证可以在国内多家9X07模块上正确稳定的执行。
3 其他组件服务功能
请自行研究实现，不做赘述了。
