如何通过蓝牙传输多通道数据？

你好，阿韦斯，
当你说“我喜欢读两个频道，但不知怎的，我不能同时从两个频道获得数据。”你到底在观察什么？你看到有什么结果出问题了吗？您是否尝试调试观察ADC API返回的值？最佳问候

  Hello Awais,
 
When you said " I like to read two channels, but for somehow I am unable to get data from both channels at the same time." what exactly are you observing at your end. Do you see any of the results going wrong ? Did you try debugging observing  the values returned by ADC APIs?

Best Regards,
VSRS

你好，VSRS，
谢谢您的回复！
ADC的数据是正确的。我可以通过示波器看到它。
但是，当我说“我无法从两个渠道获得数据”。我的意思是，在我的BLE应用程序中，我不能同时看到两个频道的数据。
意味着，我可以同时发送一个频道，但不能同时发送两个频道。
期待您的回复！
当做

  Hello VSRS,
 
Thank you for your reply!
 
The data from ADC is correct. I can see it via oscilloscope.
However, when i say " I am unable to get data from both channels". I mean that i cannot see both channels data at the same time on my BLE app.
Means, I can send one channel at a time but not both channels at the same time.
 
Looking forward to your reply!

你好，
尝试在交替通知中逐个发送两个通道的ADC输出，看看是否有帮助。
您还可以尝试将ADC通道输出附加到单个变量，并将其发送到一个通知（增加通知大小）。
我认为对于两个通道都有单独的服务，可以很容易地从相应的ADC通道读取通知并避免任何依赖关系。
顺便说一句，我看到下面的代码在附上的项目，将不会帮助您发送所有ADC输出值在一起。它总是发送CHB数据。
发送通知
ServTim.FabrAd= CyByLyPurdiaCdPosixCARIGA句柄；//用于更新。
ServTEMP.ValueVal= ValueIsCa；//读取自定义特性（数据）值。
ServTEMP.Value.ValueValueIZCHB；/ /读取自定义特性（数据）值。
ServTEMP.Value.Le= siZeof（ValueS.Ca）；/ /定义大小
ServTEMP.Value.Le= SIZEOF（ValueEXCHB）；/ /定义大小
如果（CyByrErrOrthOK＝CyLygGATSeNebug（CyByLyCon句柄，and Server Timp））
你需要有一个开关来发送CHA或CHB。

  Hi,
 
Try sending the ADC output from both channels one by one in alternate notifications and see if that helps.
You can also try appending both ADC channel output to a single variable and send it in a single notification (increased notification size).
I think having a separate service for both channels will make it easy to read the notifications from corresponding ADC channel and avoid any dependencies.
 
BTW, I saw below code in the attached project that will not help you send all ADC output values together. It will always send ChB data.
//Send notificationserverTemp.attrHandle = CYBLE_POTENADC_POTEN_CHAR_HANDLE; // For Updates.serverTemp.value.val = value_ChA; // Read value of Custom Characteristics (Data).serverTemp.value.val = value_ChB; // Read value of Custom Characteristics (Data).serverTemp.value.len = sizeof(value_ChA); // Define sizeserverTemp.value.len = sizeof(value_ChB); // Define sizeif(CYBLE_ERROR_OK==CyBle_GattsNotification(cyBle_connHandle,&serverTemp))
You need to have a switch to send either ChA or ChB alternatively.

你好，SRDS，
谢谢您的回复！
“尝试在交替通知中逐个发送两个通道的ADC输出，看看是否有帮助。”
你能详细说明一下吗？我怎么能一个一个地送他们？
期待您的回复！

Can you please elaborate it? How i can send them one by one?
 
Looking forward to your reply!

我的意思是，只需在固件中实现一个开关盒，就可以在每次执行循环时将ServTEMP.ValueVAL设置为CHA或CHB（按以下顺序发送通知）。
CHA值
CHB值
CHA值
CHB值
CHA值
CHB值
如果您认为从中央设备读取不方便，正如我之前提到的，为每个通道使用单独的服务。



     以下为原文
  I mean - Just implement a switch case in the firmware to set serverTemp.value.val to ChA or ChB each time the loop is executed (to send notification in below order).
ChA value
ChB value
ChA value
ChB value
ChA value
ChB value
 
If you think that's inconvenient to read from a Central device, as I mentioned before use separate service for each channel.
