Issue when Creating new service in nRF Connect for desktop

[masterLee]

Hi,

I am trying to create a new custom service in nRF Connect for desktop and play around with its characteristic properties.

I Use an nRF52840 DK as peripheral and my mobile as a central device.

When I set the "Write" property only and I press "save" and "apply to device" a message saying "Server setup was applied" is displayed in the log area.

Then by going to "Connection Map" tab and I start advertising with the DK, the new service is displayed and I can see it in my smartphone. So far so good (image 1).

But when I set the "Notify" or "Indicate" property along with the "Write" property and I press "save" and "Apply to Device"

no "Server setup was applied" message is displayed in the log area (image 2) and the new service is not detected in my smartphone. What am I doing wrong here?

Hi Kostoulas

I can't really say that I use this tool much, but I was able to replicate what you described . 

Could you start your application with verbose logging on post the log when you try to do step 2? You can enable verbose logging from the about tab on the BLE app. 

Regards

Hi, here is the verbose log file. I performed two tests. One without notifications and then one with notifications. I attach the verbose log file. In the verbose log file, the log part that corresponds to the first test is up to line 34 " 2024-02-23T10:09:30.822Z INFO Server setup was applied" and the rest of the log corresponds to the update with the notification enabled.
