跨连接语音呼叫的手机之间的数据传输

[英]Data Transfer between Mobile Phones Across Connected Voice Call

原文 2011-09-12 10:12:14 7 2 android/ mobile-phones/ data-transfer/ analog-digital-converter

I require a fast reliable method of sending control commands (simple data, possibly only a few dozen possible commands) to a remote system which is using a smartphone* as its onboard computer. 我需要一种快速可靠的方法来将控制命令（简单数据，可能只有几十个可能的命令）发送到使用智能手机*作为其车载计算机的远程系统。 I have deemed standard data packages used for mobile internet data transfer as too unreliable of control purposes, however I have noticed that once a voice call is initiated it is much more reliable. 我认为用于移动Internet数据传输的标准数据包过于依赖控制目的，但是我注意到，一旦发起语音呼叫，它的可靠性就会大大提高。 Has there been any development into sending data between phones across a connected call, and if not are there any known reasons a modified dialup modem in software form couldn't be used? 在通过已连接的电话在电话之间发送数据方面是否已有进展，如果没有，则不能使用软件形式的修改拨号调制解调器的任何已知原因吗？

Furthermore, could this protocol be robust enough to send back low res video and other simple numeric data? 此外，此协议是否足够健壮，可以发送回低分辨率视频和其他简单数字数据？

*Smartphone - A phone with significant processing power and ability to run custom programs (most likely with an Android based OS however am open to suggestions) *智能手机-具有强大处理能力并能够运行自定义程序的手机（最有可能在基于Android的操作系统上使用，但建议您接受）

Have you tried SMS? 您是否尝试过短信？ while you won't get video data it may work for small chunks of data. 虽然您不会获得视频数据，但可能只适用于一小部分数据。 Also if the small chunks are from the phone to a server, you may try sending DTMF down the line (however I've yet to see that working. Other than that it's customised hardware. 另外，如果一小部分是从电话到服务器，则可以尝试将DTMF发送到线路上（但是我还没有看到它起作用。除了它是定制硬件之外。）

Hmmm...this reminds me of those old TV games like Hugo...there you had a voice connection and I think the commands were given by the different tone of the key pressed from 0-9. 嗯...这让我想起了像雨果这样的旧电视游戏...那里有语音连接，我认为命令是由0-9的不同按键音给出的。 Maybe you should try something similar. 也许您应该尝试类似的方法。
