Hi! Can you tell me where to set the server and client in the program?   Because there is only a client and no server on my device, the connection is always automatically disconnected. In the case of only client, how to set the connection?

thank you very much!

Hi,

I am not sure what do you mean. The device can play the role as device and client.

The example 'wireless_uart' has the usage of this two role. If you still have the question, please describe it in detail such as which sdk and ide you use. 

Have a great day,
TIC

Hello

  the situation is like this: I hope the development board Bluetooth can only be used as a server, because if the development board is used as a client, then my device（smartphone） needs a server, but there is no server on my device. This causes the connection to always be disconnected. So how can I modify the program to connect successfully?

thank you very much

Hi,

Except the wireless_uart, the example only plays role as client or server. They won't play as other role automatically. I am not sure why your device will change its own function.

Have a great day,

hi

When establishing a connection, the development board will query whether my device has a client and a server. It must have both to successfully connect. If one of them is missing, it will automatically disconnect. Now my device has only client API but no server API, so I can't connect the development board.

thank you!

Hi,

Which example do you use? Which phone app do you use? The development board will query the device? what device?

Have a great day,

HI

I use wireless_ uart。 I'm not using apps, I'm using web pages. It's just that the Bluetooth on the web page lacks the server API, which leads to the connection failure all the time.

thank you !

Hi,

I am not sure where you get the webpage. It looks like your webpage has some problem. The develoment board won't check if your webpage has the server or client. The board start broadcasting as server and your phone connect to it. After that, the phone request the server's characteristic. Then they can communicate. Have you used our iot tool box to test? http://d.firim.pro/fgx5

hi

Yes, I have tested it with IOT box. There is no problem with the development board. This is really a problem with the web page because it lacks the server API. So I want to ask how to connect with the development board when there is only client API on mobile phone or web page.

thank you!

Hi,

If the problem is on your webpage, sorry, I can't help you. I do not have the experience about the webpage programming.

Have a great day,

hi

Excuse me, in wireless_uart_freertos , where is the program to connect the development board to the device?

thank you!

[nxf56274]

Hi,

If mcu is server. The host stack(invisible to us ) will inform the mcu using App_HandleHostMessageInput.

This function will call BleApp_ConnectionCallback.

Have a great day,
