Coyle, who got the Clarets promoted to the Premier League in 2009, left the club in January to take over at Wanderers.
Having received a hot reception from the travelling fans when Burnley were beaten at Bolton later that month, the 44-year-old is likely to be in for something similar - if not worse - during Tuesday night's Carling Cup third-round tie, but Coyle has vowed to try and keep smiling.
"In the career I've had, I've had many setbacks along the way, so in terms of mental strength, I think I have bounced back a number of times from trials and tribulations" said Coyle, who also guided Burnley to the Carling Cup semi-finals in their promotion season.
"You can't really say what the emotion is going to be until the events transpire.
"But whatever comes with it, I'll do my best to deal with it, and as always, I'll try to do it with a smile on my face."
Asked if he thought it would hurt to get a negative reaction from supporters that once idolised him, Coyle said: "I don't know, and I don't think we should get ahead of ourselves before we go there.
"I expect there will be a fair bit of criticism, but we all know as kids growing up that they can only call you a name once, and once you have been called it, you have been called it.
"If fans want to come along in that vein and voice that disapproval, then ultimately that is up to them.
"But I think that within that there will be a lot of fans who appreciate what we did and will be thankful for that.
"Who is to say Burnley Football Club would ever have graced the Premier League and had the cup runs that we had?
"There is still a big part of me that thinks about Burnley every single day because of the way that we did achieve it, against all the odds.
"What I do know, and what I would believe anybody - regardless of any opinion they have - will know, is that for every second I was in that job, I poured my heart and soul into it to achieve the best I could for that football club.
"It's fine for me to say that, but the evidence is there."
Coyle insists he would still be in charge at Burnley if he had let his heart rule over his head.
"If it was just down to emotion, and emotion alone, I would never have left Burnley," Coyle said.
"But I had to look at the bigger picture and I made a footballing decision because of the infrastructure and everything else at Bolton.
"I'd been here as a player and I knew everything that goes with that as well, and that was how it was made."
Bolton's former Clarets forward Robbie Blake has been quoted as saying he would not like to score against his old club, but Coyle feels the player's commitment to Wanderers will not be in question once play gets under way.
"Robbie Blake is a terrific professional," Coyle said.
"He will start tomorrow night and do his utmost to show the abilities and standards he has.
"It will be an emotional night for him because he went through an awful lot with Burnley in a couple of different spells, but there is no doubt that when he is out there he will be doing his utmost to try and win the game.
"Robbie was a terrific servant to Burnley and regardless of what the fans think about myself, they will give him a very warm reception."
