Hi,all. i face a problem that i used lightblue on iphone6(ios8.3 12F70) to connect my device(nRF51822),after sometime,disconnected automatic. lightblue says:The connection has timed out unexpectedly. log on iphone6:didDisconnect Error：Error Domain=CBErrorDomain Code=10 "The connection has failed unexpectedly." UserInfo=0x16fca180 {NSLocalizedDescription=The connection has failed unexpectedly.} What's wrong? How can i capture error code from device?Can someone help me?Thanks !

iPhone 6 does not follow the proper timing for BLE. As a result it provides a buggy Connection which can drop. This is a known HW issue internally at Apple, but they have not publicly acknowledged it yet. Your best solution is to decrease the accuracy of your LFCLK to the max

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_250_PPM, true);

Is this problem only for iPhone 6? Similar problems seem to occurred on iPhone 5S.

Interference with WiFi : could be a clue. Try to disable WiFi adapter to check if problem still occurrs stackoverflow.com/.../corebluetooth-and-wifi-interference

I have the same problem on my product with iPhone 5 and MCP App. Working fine with Android and MCP. I tried to change the configuration to LFCLKSRC_XTAL_250_PPM but that didn't fix this issue. Don't know what to do... Any other idea?
