Bluetooth communication development

[ILCD]

Dear:Addressee

Hello!

I have a question about the program development of Bluetooth chip.

There is no client program for blood pressure measurement in SDK (15.2.0),

拜托提供。

Please provide.

Hi,

You are right that there is not a full list of BLE examples for both peripheral and central implementations. You can find the list of examples here: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/examples_ble.html?cp=7_1_4_2 

In this case you can for instance find that the https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/ble_sdk_app_blinky_c.html is example for a central BLE device with a client application. The corresponing peripheral example is the https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/ble_sdk_app_blinky.html example with a server application.

If you look at those two examples you hopefully will get some guidance on how to make a client application to handle the https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/ble_sdk_app_gls.html example project.

Best regards,

Hello!

谢谢您的回复。

Thank you for your reply.

However, there are still grease sticks and problems, which need your reply.

In the example you told me (sdk16.0.0), only on the BLE Peripheral side have the Blood Pressure example.

In our development work,We want to use The Bluetooth MCU (nrf52832) as BLE Central.To receive another Bluetooth device's blood pressure measurement. We tried to program a ble central program to receive blood pressure measurements, but it failed.

你们能不能提供一个实例。

But in nRF5 SDK v16.0.0    the list  Bluetooth low energy examples in BLE Central ,There is no example of blood pressure measurement as client. 

Can you provide an example.

In addition, there is no explanation about the communication mode of " INDICATION" in the example you gave us.

You can provide some examples about  it.

Best regards,

ILCD-CHINA.

Hi,

You should find a few client implementations for other BLE applications in the nRF5 SDK, you need to use those as reference/guidance on how to implement this to handle blood pressure. In addition to the nRF5 SDK documentation, I would recommend to check out the message sequence charts that explain what BLE callback events are generated from the softdevice, and how the application can handle them (note that most BLE events are handled by including sdk modules such as peer manager for bonding, advertisement module for advertisement, and gatt module for MTU/DLE exchange). Though you can still find the message sequence charts useful for debugging and understanding:
