There was no OLDI msg (that includes LAM) because neither Turkey nor Sofia had any idea what that target was (I guess that was why fighters were deployed). The only thing you could see was the squawk. Sofia was transmitting on 121.5: "Traffic squawking XXXX, FL300 contact Sofia on129.1". It was repeated several times.
Actually, there was one funny transmition "Traffic squawking XXXX, with squawk, hmmm (sound of confusion)" But that is normal level of stress when you are negotiating, with military, not to shot down something, that you deeply believe, is a passenger jet.
