Error with timed out bluetooth connection

I'm getting an error with the Socket 8ci after idle time on iOS. The error is: connection to service 0x00000080 on device failed with error 305. The only way to get it to work again is to 'forget' the bluetooth device and reconnect it. Any insights on this problem appreciated.

Thanks, Mark

It is the request by the iOS device to connect to a previously paired device

When you pair an iOS device with your scanner, the iOS device starts the pairing process, but once the two devices are paired, the scanner initiates any connection to the iOS device.

tl;dr: You do not need to initiate the connection (in Bluetooth Settings) to your scanner once it is paired. Your scanner should automatically connect and reconnect without user intervention.
