I haven't played with this and can't say specific for Conky but to parse the data you could use:
bluetoothctl info 98:D3:31:F7:55:37 | grep Connected
which should just show you the connected statement. Taking it one step more:
bluetoothctl info 98:D3:31:F7:55:37 | grep Connected | awk '{ print $2 }'
should leave you with yes or no.

Hope that helps
