BTLE 4.0 - ConnectBlue低能量串行端口服务 [英] BTLE 4.0 - ConnectBlue Low Energy Serial Port Service

问题描述

我正在寻找一种通过串口（RS232）将数据从嵌入式设备加载到iPhone的方法。该应用程序需要在AppStore上，而我们的公司不属于MFI计划。

I am looking for a way to load data from an embedded device via a serial port (RS232) to an iPhone. The app needs to be on the AppStore and our company is not part of the MFI program.

在你说之前，它无法完成，我们正在研究蓝牙低能耗4.0作为一种可能的解决方案。我们可以创建一个可以将ConnectBlue的OBS421模块转换为串口适配器的设备（具有速度突发限制）。为此，connectBlue提供了自己的协议称为串行端口服务，但仅在非常高的级别上记录。

Before you say, it can't be done, we are looking into Bluetooth Low Energy 4.0 as a possible solution. We can create a device that can turn ConnectBlue's OBS421 module into a serial port adapter (with the speed bursts limitation). To that effect, connectBlue provides their own protocol called Serial Port Service, but it is documented only on a very high level.

1. 有没有人有使用此协议的经验？如果是这样，你能提供一个以这种方式建立通信的示例（目标C）代码吗？


2. 有没有人向Apple提交了这样的应用程序而没有因侵犯MFI规则而被拒绝？

还有一个问题..我尝试连接的设备仅支持EZII Escape计算机命令集标准中的串行命令（PROG ID为EZ2 2.0及更高版本）。它们看起来与常见的ATT命令不同。示例：< ESC> Gc100< EOT> 。
我是否可以通过ConnectBlue的LE-SPS发送此类命令？

One more question.. The device I am trying to connect only supports serial commands in the EZII Escape Computer Command Set standard (PROG ID of "EZ2 2.0" and higher). They look different than the common ATT-Commands. Example: <ESC>Gc100<EOT>. Any idea if I can send such commands via ConnectBlue's LE-SPS?

非常感谢您的帮助。
谢谢！

Your help is much appreciated. Thank you!

推荐答案

我没有使用过这个协议，但是从文档中看起来很简单。您应该能够采用任何核心蓝牙示例并相当快地进行调整。

I haven't used this protocol but from the documentation it seems quite straight-forward. You should be able to take any of the core-bluetooth examples and adapt it fairly quickly.

您需要寻找提供服务的外围设备 0x2456e1b926e28f83e744f34f01e9d701

You need to look for a peripheral that is offering service 0x2456e1b926e28f83e744f34f01e9d701

此服务公开两个特征 -

This service exposes two characteristics -

• 0x2456e1b926e28f83e744f34f01e9d703 阅读和放大;写入串口


• 0x2456e1b926e28f83e744f34f01e9d704 如果需要流量控制，则为credit。基本上似乎这个值表示你可以发送到设备的字节数，你可以写一个值来表示你准备从设备接收的字节数

• 0x2456e1b926e28f83e744f34f01e9d703 to read & write to the serial port
• 0x2456e1b926e28f83e744f34f01e9d704 for "credits" if you need flow control. Essentially it seems that this value indicates the number of bytes you can send to the device and you can write a value to indicate the number of bytes you are prepared to receive from the device

设备应支持完整的8位数据路径，因此我不明白为什么在发送串行命令时会出现问题。

The device should support a full 8-bit data path, so I don't see why you would have a problem sending the serial commands.

Bluetooth Low Energy从MFI计划中明确排除，所以你不会在此基础上被拒绝 -

Bluetooth Low Energy is specifically excluded from the MFI program, so you won't get rejected on that basis -

我想开发一个与Apple设备通信的配件
仅使用蓝牙低功耗。我是否需要加入MFi计划？

否。仅使用蓝牙连接到Apple设备的附件
低功耗/ BTLE /蓝牙4.0或iOS支持的
标准蓝牙配置文件不属于MFi计划。

No. Accessories which connect to an Apple device using only Bluetooth Low Energy/BTLE/Bluetooth 4.0 or standard Bluetooth profiles supported by iOS are not part of the MFi Program.
