EC20功耗测试示例

本示例支持LINUX和OPEN-LINUX开发环境，将对讲中使用的数据通信做了抽象，意在能够尽可能的简化测试EC20模块上的功耗，以及网络延迟问题
1 功能说明
1.1 心跳维持
-
UDP心跳：默认10s
#define TEST_UDP_TIMER 10.0 //UDP Ping Timer
对讲终端2/3G制式时此值为3s, UDP端口有时效，无限增大此值，不同网络制式下一定会出现丢包。
但是太小就会引起功耗上升。 -
TCP心跳：默认60s
#define TEST_TCP_TIMER 60.0 //TCP Ping Timer
对将默认为60秒，TCP作为保持链路使用，此值不是影响终端功耗上升的关键点。
1.2 业务流程
- 开始讲话 「模拟终端A」
static void start_speak(poc_context* poc_ctx);
发送讲话请求消息，回应：
static void on_request_mic_ack(poc_context* poc_ctx, char* msg);
请求成功后，就开始发送语音数据:
//start send udp data timer
ev_timer_set(&(poc_ctx->timer_udp_data),TEST_UDP_DATA_TIMER,0);
ev_timer_start(poc_ctx->loop,&(poc_ctx->timer_udp_data));
-
停止讲话「模拟终端A」
static void stop_speak(poc_context* poc_ctx);
发送停止请求消息，回应：
static void on_drop_mic_ack(poc_context* poc_ctx, char* msg);
请求成功后，就会停止发送语音数据：
ev_timer_stop(poc_ctx->loop,&(poc_ctx->timer_udp_data)); -
发送语音「模拟终端A」
开始发送语音数据，每200ms发送一包udp_data：
send_udp_data(poc_ctx); -
有人开始讲话「模拟终端B」
收到有人开始讲话通知:
static void on_member_get_mic(poc_context* poc_ctx, char* msg); -
有人停止讲话「模拟终端B」
收到有人停止讲话通知:
static void on_member_drop_mic(poc_context* poc_ctx, char* msg); -
收到语音数据 「模拟终端B」
收到语音数据:
static void on_data(poc_context* poc_ctx, char* msg);
2 测试及统计
2.1 编译
终端使用cmake来管理的源码，需要安装cmake。
安装完后，配置系统根目录的路径, 修改./depends/arm-oe-linux-gnueabi.toolchain.sh:
set(OPENLINUX_TOOLCHAIN_DIR /opt/ql-oe/sysroots/x86_64-linux/usr/bin/arm-oe-linux-gnueabi)
set(OPENLINUX_ROOT_DIR /opt/ql-oe/sysroots/mdm9607)
对于EC20编译执行make-arm-oe.sh
对于LINUX编译执行make-linux.sh
无错误的话会生成poc_client应用(linux在build目录，openlinux在bb目录)
2.2 程序部署
-
部署
pocecho.py
需要linux+python环境，并且服务器有外网IP，UDP/TCP各一个可用端口
运行python pocecho.py start|stop|restart -
PUSH终端应用
连接EC20到PC，adb push poc_client /data/
可以使用的组合：
A（PC-LINUX） + B（EC20）：A发送，B接收，统计B输出的数据
A（EC20）+ B（EC20）：统计接收端输出的数据
注：程序中用到了对时功能，需要root权限修改本地时间才会生效（PC-LINUX情况）
- 修改服务器IP和端口
poc_def.h中HAL_OPENLINUX表示为OPENLINUX(EC20):
//SERVER ADDRESS
#ifndef HAL_OPENLINUX
#define TEST_SERVER_IP "192.168.40.103"
#define TEST_SERVER_UDP_PORT 10071
#define TEST_SERVER_TCP_PORT 10073
#else
#define TEST_SERVER_IP "119.254.102.206"
#define TEST_SERVER_UDP_PORT 10075
#define TEST_SERVER_TCP_PORT 10078
#endif
2.3 数据统计：
条件：
- UDP网络制式：电信/移动/联通，2G/3G/4G
- 心跳间隔：3/5/8/10 秒等
- POC对将消息
数据：
-
待机情况下耗流(区分不同运营商及网络制式)
-
收发数据情况下耗流
待机情况,休眠情况 -
开始/停止讲话时间
-
收到有人开始讲话/停止讲话的通知时间（MODEM收到数据的时间）
待机情况,休眠情况，关心的是服务端推送数据到达的延迟有多少 -
收到第一包别人语音数据的时间（MODEM收到数据的时间）
待机情况,休眠情况，关心的是服务端推送数据到达的延迟有多少 -
待机进入休眠的时长
2.4 日志输出解释
poc_def.h定义了协议的标识，如下：
