Kaku ayct-102 remote not working in 2.5.1 rc3

I use the remote for triggers and noticed in the latest bèta firmware that the remote doesnt work anymore. Also re-pairing doesnt work. Ptp for a long time Also doesnt work. I Also have another kaku remote and that one works. It seems there is something specifically wrong with the Ayct-02. Van anyone confirm?

Empty battery ??

I first replaced the battery, that wasnt the solution

I tried an another kaku remote which was the same and that one worked. It looks like the remote is broken. Topic can be closed
