It has come to our attention that iOS update 8.3 is unable to receive GPS data from Cygnus Pro Wireless and Cygnus Home Direct. In combination with Bad Elf, our engineers were able to determine that all accessories that use Apple’s 30-pin connection protocol are no longer able to correctly forward location data. Bad Elf has posted a similar notice on their blog. This also affects other 3rd party apps that use location services, such as ForeFlight.
Update (Tuesday 30-June): With the release of iOS 8.4, the bug that prevented most GPS accessories from providing location data has been fixed. Redbird Cygnus customers experiencing issues with iOS 8.3 should update to iOS 8.4.
Update (Monday 13-April): We've passed all of the necessary information to Apple Support and got confirmation over the weekend that it has been passed to the correct team. We're optimistic it will be fixed in the next iOS 8.3.x release, and will post updates as we receive them.
Update (Thursday 16-April): We're still awaiting any news from Apple. In the meantime, we’re exploring several possible workarounds. We have confirmed that the beta iOS 8.4 released earlier this week has the same GPS issue. Some customers have reported successfully downgrading their iOS back to iOS 8.2, but we can’t recommend that process to our customers — it’s not supported by Apple and requires a complete wipe of your settings/apps/data.
Update (Tuesday 28-April): Apple released an iOS 8.4 beta 2 update to developers and beta testers yesterday. Unfortunately, due to the confidentiality requirements of these programs, we’re not allowed to disclose any non-public information about this beta software — including how it affects the iOS 8.3 bug affecting external GPS receivers like ours.
Update (Tuesday 09-June): IOS 8.4 EXPECTED TO LAUNCH BY JUNE 30 WITH GPS FIXES
During Apple's Worldwide Developer Conference (WWDC) keynote yesterday, Apple announced several new services that will be included in iOS 8.4 and available by June 30th. This release is expected to fix the open iOS bugs affecting external GPS receiver accessories. Although we had hoped for a 8.3.1 update or 8.4 release to launch much sooner than this, at least we now have a firm date.
Update (Tuesday 30-June): With the release of iOS 8.4, the bug that prevented most GPS accessories from providing location data has been reported as fixed. Our preliminary tests indicate that iOS 8.4 allows Cygnus to function properly; and that it doesn't seem to introduce any new bugs. Bad Elf also went through some extensive testing with iOS 8.4 and are reporting that it passed all of their bench tests. We recommend anyone experiencing issues with iOS 8.3 upgrade to iOS 8.4 and contact Redbird Support if it does not resolve your issue.
