basic central tutorial please

[PingISTL]

Dear all

I am looking for a tutorial like this https://devzone.nordicsemi.com/guides/short-range-guides/b/bluetooth-low-energy/posts/ble-central-tutorial

It sounds quite helpful, but it is a bit old and tools are outdated and functions look different, some links are not available anymore, could someone point me to a newer one please? I am new and use VS Code and latest nrf connect, and aim to develop a generic central application to make connection and exchange data. 

Thank you .

It's really up to you how you implement and do this. 

If you are implementing a BLE profile, then you need to follow the BLE profile and service specification as specified by bluetooth.

If you are implementing a proprieatary BLE application, then you can do this whatever you like (e.g. there is no need to put any UUID in the advertisment if you don't want to).

Best regards,
Kenneth

Thank you for reply, Kenneth

I am developing a central application, and needs to connect to peripherals which are connectable and exchange data, You are right there are some peripherals don't advertising services or anything, in that case there is no need to discovery anything and that is not what I am discussing here.

Please advise further on how to implement BLE profile and service specification, I need to start from a simple application like how to talk to peripheralLBS example? and need to make it generic later. I am not sure what I need to do after discovery of the ATT[ ] & handles.

Your input is much appreciated.

You ask legit quesitons, but it's kind of out of the scope of the tech support we provide to tutor developers on how BLE works and designed, we provide examples that show various usage, and you should from looking at the example implementation get some understanding on how it works, but you still need to also look at other sources for knowledge on how BLE is and how it can be used.
