如何使用Android Java代码与运行UART的赛普拉斯BLE设备通信到BLE Central项目？

你好，
UART BLE中央项目是关贸总协定客户。这意味着它可以在外围设备上执行读写和来自外围设备的提示通知。
因此，移动应用程序外设必须充当GATT服务器（从CyPress设备接收写入并向CyPress设备发送通知）。
不是从Android应用程序发送通知，而是尝试发送写？如果是这样，写会失败。
您需要从Android应用程序发送通知，该通知将在UART中央项目的AppsBel.c中触发CyByLyEvtGATCK-HANDLYValueNTF事件，然后由HealuuARTrxCuffic API处理。
当做，

  Hi,
 
The UART BLE Central project is a GATT Client. Which means it can perform read and write on the peripheral device and accpet notifications from the peripheral.
 
So the mobile app peripheral must act as a GATT Server (Receives write from the Cypress Device and sends notifications to the Cypress device).
 
Instead of sending notifications from the android app, are you trying to send write? If so the write would fail.
 
You need to send notifications from the android app which will trigger a CYBLE_EVT_GATTC_HANDLE_VALUE_NTF event in the app_ble.c of the UART Central project and is in turn handled by the HandleUartRxTraffic API.

你好Madhu
这是非常有洞察力的信息，因为我确实尝试用“WordRealEnsPysPuns:CDD2”特性更新，然后更新服务。我将修改我的代码来使用NoTcCube只发送“通知”CDD1特性来发送更新。
我会让每个人都知道我的进步。
谢谢，
罗翰

  Hi Madhu-
 
This is very insightful information, as I was indeed trying to update with the  "WriteNoResponse" CDD2 characteristic and then updating the service. I will modify my code to send updates using Notifcations only which is the "Notify" CDD1 characteristic.
 
I will keep everyone posted with my progress.
 
Thanks,
Rohan

Madhu -
你们的议会非常棒。这正是我所做的。您使用通知特性的指令工作得很好。现在我可以接收WrrECHAR请求，也可以向CyPress设备发送通知。
再次感谢你的帮助。

Your counci was superb. That is exactly what I was doing. And your instruction to use the notification characteristic worked perfectly. I can now recieve writechar requests as well as send notifications to the cypress device.
 
thank you again for your help.
Rohan

Madhu -
我有一个令人费解的问题要问你。为什么我能从我的周围发送通知，中央只有一次？
由于某种原因，当我连接到设备上的。我得到一个描述符写请求从中央[ 1 ]然后我完成请求和改变的特征我的值发送回信息（cdd1）和发送notificaiton，我成功得到预期的反应。然而，当我试图发送一个通知，它失败了。我什么也收不回来。这是因为我不再得到描述符写来自客户端的请求？都是由cyble_evt_gattc_handle_value_ntf通知事件处理？
请让我知道你对此有何看法。
罗翰

  Madhu-
 
I have a puzzling question for you.  Why am able to send notifications from my Peripheral to Central only once?
 
For some reason right after I connect to the device over BLE.  I get a Descriptor Write Request from the Central [1,0] and then I complete the request and send back informaiton by changing my value in the characteritic(CDD1) and send notificaiton, I succesfully get the expected response.  However, when I try to send a second notification, it fails.  I recieve nothing back.  Is this happening because I am no longer getting Descriptor Write requests from the client?  Are all notifications handled by the CYBLE_EVT_GATTC_HANDLE_VALUE_NTF  event?
 
Please let me know what you think about this.
