Connection with pc through Matlab failure.

[paulo_g]

I am following this series of tutorial "BLE Advertising, a beginner's tutorial", BLE Services, a beginner's tutorial.

The problem is after establish a fresh advertising without any services. The connection between ps and nRF52 device through Matlab is working well.

But after i creat a service in the same code, didn't change anything else, the connection can not be establish anymore.

There is nothing i can do in Matlab part. So i need some help here, which parameter in advertising init or service init part will infect these connection?

Thanks for yout help.

Hi!

 

But after i creat a service in the same code, didn't change anything else, the connection can not be establish anymore.

 Okay, could I just see the application code running on the nRF52?

Best regards,

Hi Heidi,

https://github.com/paulo130/servicetutorial.git

this is my project file. it can compile under SDK15.0.0_a53641a enviroment.

in the main code, there is our_service_init (&m_our_service); in line 356.

If you delet this line, device running this project can connect with pc through Matlab by ble() command.

But if you keep this line, ble() command can not work anymore.

Thanks a lot.

Okay, and do you see any errors in the log output? Could you attach the log output?

Are you basing this code off of anything, or did you write it from scratch?

Where are you setting &service_uuid.type?

ok  i konw what's wrong.

To use ble() function in MATLAB the ble device should not connect  or paired with PC.

Hope this can help others.

Thanks.
