Q1。请提及用于将数据发送到DSPS应用的功能, Q2 . also specify does DSPS source code API functions to send data through BLE and smartband IOT source code API functions are same
i am using user_send_ble_data(p_data , length) function in DSPS source code to send the data to DSPS app , is there any other function available to send data over BLE to DSPS
2. The DSPS and IoT project are totaly different projects using totally different custom profiles. In essence both are using notificatios/indications and write and read commands in order to communicate (as all the BLE projects do) but the architecture of the two reference designs is totally different. The DSPS emulates a serial port over a wireless link using 3 characteristics and the IoT sends sensor data using 10 characteristics one for each sensor or proccessed value.
Were is the code trapped and goes in an endless loop ? When you read the I2C (Read_Sensor()) is invoked you see that your code is trapped ? I dont get about what delays you are talking about, you have inserted delays when reading the I2C sensor ?

hi GauravBansal i am using tha AN-B-029_V1.0 for custom profile to read data and send via bluetooth , this rar extention has the tutorial pdf also..that would be helpful for u
Thank you for the reply. I worked on the sample128 and fathomed through the doc AN-B-029 Developing a Bluetooth Smart custom profile_V1.0 as you suggested. This has led to an effective communication between the mobile app Blueloupe and my DVK board. But I am still not able to figure out how to integrate my board to any sensor and also through the DSPS app. If you could point me to some more docs or guides regarding this, I'll be really grateful.
Hi prasanth.velliyangiri,
我想你可以使用app_uart_push()以便将数据从I2C推送到BLE缓冲区,这是由UART的接收调用正常调用,它将数据推入BLE缓冲区。您可以找到有关串口应用程序的所有可用信息以及串行端口服务参考应用程序注意中的最重要功能。
谢谢mt_dialog.

Hi prasanth.velliyangiri,
这不是通过对话框实现的,您必须将DSP的现有实现调整为您的需求,以便将数据发送到DSPS应用程序,可以将USER_PERIPH_PUS()(用于SDK5版本)功能作为示例并调整您想要的函数效率才能将I2C数据从I2C传感器推到BLE缓冲区而不是UART,然后再到链路的另一侧。如果您不想模拟串行端口,并且只想通过BLE发送传感器数据,您不必使用DSPS应用程序,但每次具有传感器数据时都使用自定义配置文件实现并通知客户端。如果您需要一个示例,您可以查看app_ble_peripheral,其中有一个示例以触发稳定速率间隔的通知。
谢谢mt_dialog.

Hi prasanth.velliyangiri,
1.正如我在我的前一篇文章中提到的DSPS应用程序模拟串行通信,如果你只想将数据发送到链接的另一侧,你可以使用比DSPS应用程序更简单的方式,你提到的具体功能拉动数据来自UART填充的DSP缓冲区,并将其作为通知发送到链路的另一侧。这是DSP使用的功能,以便将数据从缓冲区发送到链路的另一侧。
2. The DSPS and IoT project are totaly different projects using totally different custom profiles.

}
上面的代码工作正常,我在DSPA移动应用程序上获得一些数据,如果我启用//我的req注释,代码进入无限循环,我无法获得任何数据
以上代码,在i2c read_sensor()中添加延迟会影响代码?,即使在IOT项目和I2C EEPROM中我也没有看到任何延迟......
谢谢你...

Hi prasanth.velliyangiri,
我读了上面的对话,我也在努力解决非常相似的东西。但我刚刚开始工作。您能否请帮助我参加项目的第一部分I.E.阅读来自传感器的数据。如果你能指出我应该看的档案以及我需要照顾的确切功能会很棒。
谢谢。
