Unable to start Learn Code
I have installed this module to my homebridge but can't learn anything with my RM mini 3 S/N RM312208xxxx. Whenever I tapped "Learn" button in my home.app but always returns Error as below.

Can anyone help me for my issue?

Btw I've confirmed I can reach out my RM mini by ping command but in the case of above command, no message returned.
