Hi all.

I'm developing a homekit accessory, and I'm currently doing mfi certification. The developed product is smart door lock and supports homekey.

Use below tools

iPhone 13 , XR , 11

HomeKit Certification Assistant 6.4.0

HomeKit Accessory Tester 9.3.0

HomeKit Companion 2.4.3

I recently updated my iPhone 11 to iOS 18.1 and if I proceed with TCL0029 of HCA, there is a problem.

Companion has no response to "SELECT step-up AID". (Unified Access Air Protocol Specification R1.1.pdf)

The companion outputs the following message. "Step-up Encountered Error"

There is no problem with iOS 17.x. Products that have already been certified are experiencing the same symptoms. There is no problem with using homekey in real life, only problem with companion.
