Hello, last night I installed the iOS beta SDK 2.0 beta. Commit: 8c416f8fcf1b71c93b012a4141b3b722b2b1a7c1 [8c416f8]
Once installed I updated my beacons to Estimote OS 2.0.
Since then I have not been able to connect to the motes with the virtual beacon software (https://itunes.apple.com/us/app/estimote-virtual-beacon/id686915066?mt=8).
The beacon's do not show up in the Estimote 2.0 beta example functions. Only under the firmware upgrade where I can see the BLE MAC address.
If I scan with BTLE Explorer I can see the device. I also can see the device with Nordic BLE sniffer through wireshark and through the Android SDK on a Nexus 5.
The following information was extracted from wireshark.
btle.advdata.manufacturerdata = 4c:00:02:15:b9:40:7f:30:f5:f8:46:6e:af:f9:25:55:6b:57:fe:6d:4a:fa:fd:63:bc
