Errors when expanding services in nRF Connect for Desktop

[nrbrook]

When expanding some services using nRF Connect for Desktop (Mac) and the nRF52840 USB dongle I get the following errors:

I think this occurs on services with a larger number of characteristics, but I'm not sure.

Hi,

Thank you for reporting this issue. Can you provide the nRF Connect log as well? There should be an "Open log file" button top right of the log panel (next to "Clear log" and "scroll automatically" buttons.)

You should also find the logs at default location:

C:\Users\<user name>\AppData\Roaming\nrfconnect\pc-nrfconnect-ble\logs

The 'addVsUuidToDriver' error occurs the first time I attempt to expand the service, the 'reduceApp' error occurs the second time after which the service is stuck in a 'loading' state with the spinner.

Hi,

Thank you for the additional information.

It turns out with the current discovery procedure implementation there is a limitation for the number of unique 128 bit base UUIDs that can be discovered. This is something that we will look into for future releases of nRF Connect.

Thank you again for reporting the issue. Bug reports are always appreciated!

Hi Terje,

I have the same problem. Can you tell us, when you plan to fix this problem? The only diference is that we use the windows version. In your mobile Version of nrf Connect, we can open all attributes without error.

Hi,

Unfortunately I do not know when this will be implemented. From what I can tell support for SoftDevices version 6 is the main objective at the moment, and other improvements are likely to follow after that.
