NRF52832 device not visible on iphone XR

[Mike Hibbett]

Hi all, I have an odd issue with an iphone XR. The NRF Connect for Mobile application can see adverts from the device when scanning, but the device does not appear in the bluetooth menu on the phone, nor is it discovered by my flutter application. On an iphone 7, or an iphone 12 pro, the device is detected correctly.

Has any one else noticed issues specific to the iphone XR? If so, I can go into details of OS version etc (the iphone XR was upgraded to the latest OS release, but that did not improve things.

Regards,

Mike

Hi Mike,

I asked around a bit about this issue. Usually when devices doesn't appear on the Bluetooth menu, it is either because the device is bonded with another device, or because it doesn't contain a service that the phone finds "useful" such as headphones and keyboards. So if the device is not advertising with a familiar UUID, then the phone will hide it from the bluetooth settings display.

Not sure about the custom application, but this might either be a problem with iPhone XR or because the device is bonded with another iPhone. Since the device appears on other iPhones, then perhaps the device is bonded. Could you try to delete the bonding data using the nrfjprog --eraseall and refresh the application.
