NimBLE

[er-bsman]

@h2zero,
hi,I have got the services, characteristics when scanned the ble device using the Mobile app.

Now, I used the NimBLEClient::discoverAttributes() fun to discover the service of the device. I want to get the Characteristics and want to use the GATT wite() fun. Kindly help me out, how to do it.

Once you have a client connected you can write to a characteristic by calling setValue from there or get a reference to the service and then the characteristic and calling write on it.

Have a look at the examples and documentation to see how this is done.

hi,i did tried. I got the services and could not get the characteristics, descriptor using the services.

Is it something like this i need to do?

[h2zero]

Yes that's one way to do it. Give it a try and see what happens, let me know if you have an issue.

I tried to get the characteristics from the services but I could not. I would appreciate, if can you provide with me some examples or documentation on how to do it. My only concern is:

As I mentioned earlier, I have got the services, and I need to get the characteristics of that by the reference of the services and then to the descriptor after that I need to GATT write to be done.

I managed to get it all the characteristics and the descriptor related to the services. Thanks.
