i'm looking for a way to power on or off the GPRS adapter programatically. If you're already using the Smart Device Framework , the ability is already there in the API, as you can see in this blog entry (the blog is for WiFi but the phone radio and bluetooth work the same way). THe other option is to call ChangeRadioState in ossvcs.dll yourself (that's what the SDF is doing). 来源： https://stackoverflow.com/questions/1164057/power-on-off-gprs-on-windows-mobile

In my iOS app, I support to work online as well as offline. For this I have used Apple's Reachability code . Now I want to show user is offline if the cellular mobile network is EDGE or GPRS or bad/slow network. I have used the below code( Found solution ). Code: CTTelephonyNetworkInfo *telephonyInfo = [CTTelephonyNetworkInfo new]; NSLog(@"Current Radio Access Technology: %@", telephonyInfo.currentRadioAccessTechnology); [NSNotificationCenter.defaultCenter addObserverForName:CTRadioAccessTechnologyDidChangeNotification object:nil queue:nil usingBlock:^(NSNotification *note) { NSLog(@"New Radio

I'm writing an application for android. My problem is that I want it to force the connection in GPRS and not use wi fi. I have a solution like below, but this causes the crash of the application at start. ConnectivityManager CM = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE); CM.setNetworkPreference(ConnectivityManager.TYPE_MOBILE); I also added the below setting lines into manifest file. uses-permission android:name="android.permission.WRITE_SETTINGS" uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" uses-permission android:name="android

Is it possible to get all open or cached gprs connections on windows mobile and programmatic force them to close? Ive been looking at connection manager api but cant seem to find methods I to do this. Regards Tony Connection Manager can be notified that you're no longer using the connection by calling ConnMgrReleaseConnection , but that does not forcibly close the connection. It is closed based on the lifetime caching defined in the registry (HKEY_LOCAL_MACHINE\Comm\ConnMgr\Planner\Settings), as well as any info passed in the Release request. (BTW, these APIs are wrapped in the OpenNETCF

I am using simcom900 modem,I am successfully able to establish GPRS connection and send data from my module to server.I am using 2g Airtel SIM and I have given APN name as "airtelgprs.com".I have also tried by giving different APN names which are not related to airtel network then also I could establish connection and transfer data to server. Please let me know how is this possible? With the SIM unlocked, try entering AT+CGDCONT? Now you should see all the stored contexts, something like this: +CGDCONT: 1,”IP”,”airtelgprs.com”,”0.0.0.0″,0,0 +CGDCONT: 2,”IP”,”other apn”,”0.0.0.0″,0,0 +CGDCONT:

I want to develop an application that disables the Background Data (new feature in Android 1.5) and Auto Sync and then enables GPRS/EDGE connection and vice versa. I figured out how to enable/disable GPRS/EDGE by changing the APN settings. (weird solution. However; Android developers couldn't think a user may want to disable GPRS/EDGE) But, I couldn't find a way to enable/disable Auto Sync and Background data. I investigated the Android code and as I understood, the Sync operation is an intent. So, I wanted to reach with putExtra to the intent and trigger the enabling/disabling. But; I couldn

I'm stumped with sending data to a remote server , I'm able to send a post request but not sure how to add data which is then received by the server. I've went through the datasheet http://www.jarzebski.pl/datasheets/SIM900_https-121018-1.00.pdf tried # usual at+sapbr=1,1 set up +HTTPINIT +HTTPPARA = “CID”,1 +HTTPPARA="URL","IP-ADDRESS:PORT" +httpdata=100,10000 # Where do I add the post data ? +httpaction=1 which sends the http post request. But how do I add data - I've tried adding it to the url ?key=val but no joy - any help here will be appreciated httpdata=100,10000 means that SIM800

前言 一,该程序需要的基础知识: https://www.cnblogs.com/yangfengwu/category/1566194.html 所有源码开源,请自行学习 　　 二,此程序兼容SIM800 如果想绑定SIM800,请把其IMEI号,生成二维码,用手机APP扫描. 实现功能概要 　　GPRS模块发布的主题: device/设备IMEI号　　GPRS模块订阅的主题: user/设备IMEI号 　　APP通过扫描二维码获取GPRS设备的IMEI号,然后设置订阅的主题:device/设备IMEI号　　发布的主题:user/设备IMEI号 　　注:实际上和上一节代码唯一不同的地方是控制GPRS连接TCP服务器,然后实现透传.其它程序完全一致! 　　后面再有一两节,我便告诉大家如何移植当前我的MQTT处理程序到自己的项目,只要自己的模块可以实现TCP,便一定可以实现MQTT 　　因为本身MQTT就是个TCP服务器而已.你按照他给的规定发数据,它就帮你转发数据了而已. 　　我当时封包就是为了大家无论用的什么模块,都可以分分钟移植上MQTT! 　　授人予鱼,就要给一条有很大价值的鱼! 　　说实话哈,我用我的包移植上这个程序,只用了不到10分钟.其实如果有现成稳定的流程的知道怎么控制模块连接TCP了,也就5分钟. 一,硬件程序 　　 1.1:
