Could someone look at those and tell me > what might be wrong ? Looks like the NUC is triggering paring while RPI 3 doesn't, perhaps at some point you had the NUC paired but you remove the link-key locally (by removing the device) but iOS still has the link-key which makes it trigger authentication which fails with the following error: Reason: Remote Device Terminated Connection due to Low Resources It could be that the iOS device is running out of slots to store the new link-key, anyway try removing the NUC from the iPhone and see if that helps. -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
