Hi There, I am also facing this problem, but I am stuck because my device is not shown in the Bluetooth panel. It is unclear how to get it to show up in this panel, but I have an iOS app that uses CoreBluetooth that can see it advertising and can pair with it. nRFConnect from Nordic can also see it and connect/pair. But I have deleted the bond table on my device and now I am completely hosed because I cannot reconnect because I always get this error. I tried deleting the Network Settings and power cycling the phone but it doesn't help - it is permanently locked out now. So I have two questions: How can I recover in this situation? How can I get my device to show up in the Bluetooth settings (both showing scan results and as a previously paired/device) so in the future I can "Forget" it? Thanks, Mark

What is it that triggers iOS to show my device as a paired device on the Bluetooth settings screen after it is paired? I have managed to make it appear once or twice and seems to depend on the advertising data and scan response. It looks like I must have the Complete Name in the advertising data (not the scan response) but there is some other "switch" as well. It is working sporadically for me at the moment. Could someone tell me what the heuristic is?
