AP侧新增AT命令

以新增命令“+TEST”为例。

1. 在Modem侧添加自定义的AT Command的注册。在*modem_proc/datamodem/interface/atcop/src/dsatclient_ex.c下的LOCAL byteallowed_list[][MAX_CMD_SIZE]数组中添加定义：

LOCAL byte allowed_list[][MAX_CMD_SIZE]={......,"+TEST",........,""};

2.在*modem_proc/datamodem/interface/atcop/src/dsatcmdp.c的dsat_result_enum_type dsatcmdp_process_cmd_forwarding ( void ){ 中新增判断条件：

if ((......

&& ( 0 != dsatutil_strcmp_ig_sp_case( (const byte*)token_ptr->token.name,

(const byte *)"+TEST") )

......

)){

3.在Vendor下添加AT Command的注册。在*/vendor/qcom/proprietary/data/ATFWD-daemon/atfwd_daemon.c下的qmi_atcop_at_cmd_fwd_req_type atCmdFwdReqType[]数组中添加定义：

{ //AT command fwd type

1, // Number of commands

{

{ QMI_ATCOP_AT_CMD_NOT_ABORTABLE,"+TEST"},

}

4.在\vendor\qcom\proprietary\telephony-apps\ATFwd\src\com\qualcomm\atfwd下新增

AtTestCmdHandler.java文件，可以复制其他已有的Java文件，修改内容，如：

packagecom.qualcomm.atfwd;

importandroid.content.Context;

//importcom.qualcomm.qcrilhook.QcRilHook;

importandroid.util.Log;

publicclass AtTestCmdHandler extends AtCmdBaseHandler {

private static final String LOG_TAG ="AtTestCmdHandler";

//QcRilHook qrh = null;

public AtTestCmdHandler(Context c)throws AtCmdHandlerInstantiationException{

super(c);

}

@Override

public String getCommandName(){

return "+TEST";

}

@Override

public AtCmdResponse handleCommand(AtCmdcmd) {

String result = null;//需要最后显示的结果

String atTest= null;

boolean isAtCmdRespOK =false;

switch (cmd.getOpcode()) {

case AtCmd.ATCMD_OPCODE_NA_QU:

Log.i(LOG_TAG,"ATCOMMAND_TEST");

result = "+TEST:" + "at_command";

isAtCmdRespOK =true;

break;

default:

Log.d(LOG_TAG,"atTest OpCode Error");

result =cmd.getAtCmdErrStr(AtCmd.AT_ERR_OP_NOT_SUPP);

break;

}

return isAtCmdRespOK ? newAtCmdResponse(AtCmdResponse.RESULT_OK, result) :

new AtCmdResponse(AtCmdResponse.RESULT_ERROR,result);

}

5.在\vendor\qcom\proprietary\telephony-apps\ATFwd\src\com\qualcomm\atfwd

\AtCmdFwdService.java中把新增的AtTestCmdHandler.java文件加到HashMap集合中：

publicAtCmdFwdService(Context c)

{

mContext = c;

mCmdHandlers = new HashMap<String,AtCmdHandler>();

AtCmdHandler cmd;

......

try {

cmd = newAtTestCmdHandler(c);

mCmdHandlers.put(cmd.getCommandName().toUpperCase(), cmd);

} catch (AtCmdHandlerInstantiationExceptione) {

Log.e(LOG_TAG, "Unable toinstantiate command", e);

}

......

}

这样，一条新的AT命令添加完成。
