Hello, thank you for your reply.
When I have time, I will simplify the example project.
It's smaller files that are easier to upload and use.

Hello, I don't know how to attach the engineering documents here.

The master side seems to be sending the write command and I see that in your nRF Connect snapshot the data is not the same. The short UUID also seems to match, but I am not still able to connect the dots on why the write doesn't get through. There does not seem to be any error in the sequence. Can you attach a simple project for me to try it out on my desk?

Hello

Thank you very much for your reply.

And test it carefully with software.

The monitor software shows that the host sends data, but the slave does not return data.

But send data using the nrf_connect connection on the mobile phone.

Nrf_connect allows you to see data fed back from the machine

The following figure

The above five figures,
The first three diagrams are connection and enabling machine notify.
The fourth figure is the data sent by the host.
The final figure is the data returned by the mobile phone nrf_connect connection test slave notify
Let's see what the problem is. Thank you.

Hi Creator,

I have to read your question three times, I am still a bit unclear on what the problem is.

I am assuming that you have problems listening to data from central to the slave, but I do not understand the images or information given.

Can you actually see it in the sniffer, if the central is sending data to the slave and if yes, then we can try to debug to see why you do not get an event for that in the application?
