UART/NUS no longer functional on latest nRF toolbox iOS app

[epeterson117]

Hi,

The most recent version of nRF Toolbox v5.0.4 for iOS cannot see or connect any of my devices (nrf52832, SDK 15.3.0, s132_6.1.1) in the NUS/UART section of the app. It was working fine in the previous app builds as recently as a few weeks ago.

Has anyone else had the same issue recently? Is there an update required to the UART service on the peripheral side?

Thanks

Hi,

Thanks for sharing these useful information, I will need a bit more time to get help from our development team.

Can you also share your current iOS version? Did you update to iOS15 Beta? If yes which exactly?

Best regards,

Charlie

iOS 14.7.1. Some of my colleages have also tested on their iPhones with the same result.

Thank you for looking into this, Charlie - it is greatly appreciated! We rely on these tools in the field and we miss them dearly at the moment!

Is there a way to go back to an older version of the nRF Toolbox app for iOS?

Charlie, it is also worth noting that when I select the DFU service page, I can see my devices advertising normally. We have custom python applications which also can see the scan response. 

It seems the issue is isolated to the UART scan only.

Hi epeterson117,

I think I know the reason.

I added filter to scanner in NUS in the latest version.  But not all devices advertise NUS service. That's why you can't see it in the list. 

I gonna fix it today and publish new version. 

You can't roll back to previous version, so you have to wait a couple of days until the new version is available in the AppStore.

Hi Nick,

This fix has addressed the issue. We were not advertising NUS service. With the filter disabled, I can connect to our devices. 

Thank you!
