Apple's iPhone 7 and iPhone 7 Plus as of right now can only handle 6 Chipolos (no other Bluetooth devices connected) at once, there are some hardware/software issues when multiple Bluetooth devices are trying to connect to an iPhone 7 or iPhone 7 Plus and as such the limit was decreased in order to provide support for our users. We highly suggest contacting Apple regarding a resolution as this is not related to Chipolo but all Bluetooth devices.
If you do connect more devices your phone will show you a ‘Bluetooth has been disabled’ message.
