Hoppy turned down the prosecution's offer of pleading guilty to a harassment violation and agreeing to go to anger management.
A judge adjourned the case to April 26 and ordered Hoppy to refrain from contact with Frankel.
"Jason Hoppy rejected the plea offer, which was pleading to a harassment violation with a requirement of anger management and a full and final order of protection in favor of the defendant," the New York district attorney's office confirmed to People.
"There is still a temporary order of protection in place for the defendant."
Frankel was granted an order of protection against Hoppy following an incident Jan. 27.
Hoppy was arrested after showing up at daughter Bryn's school, and had reportedly been sending Frankel threatening messages for months.

"The complainant said Hoppy had sent numerous emails and FaceTime calls numbering in the hundreds after a cease and desist letter was sent on Nov. 22, 2016," an NYPD spokesperson said at the time.
"On Friday, Jan. 27, [Hoppy] approached [Frankel] and a friend at her child's school at around 8:15 a.m. and tried to provoke a fight," the spokesperson added.
"He said, 'I will destroy you, you can get all the lawyers you want, you've been warned."
Frankel and Hoppy split in 2012 after two years of marriage and finalized their divorce in July.
