advance information

[Pidginboy]

In spite of my advance information, the Engineer did not turn up for the scheduled meeting.

Please look at the bold phrase, and please tell me if it gives the meaning that I informed him in advance so he could attend the meeting?

It doesn't really have that meaning for me. I would have taken it to mean that I had been given or had obtained information prior to the meeting that indicated that the engineer would be there.

To get the meaning what I wish to communicate, how should I string together the phrase in the place of that in the bold form, please?
