Freematics OBD-II Emulator MK2 stopped working for KWP protocols

[smudum]

My Freematics OBD sim -> Freematics OBD-II Emulator MK2 suddenly stopped working for the KWP protocols.
I have 4 of them. Initially everthing worked but as the time passed by, each one started behaving like the above (not working for KWP protocols)
Can I get some support on this issue?

Thanks
Swathi

There is a bug about KWP protocol in MK2. I recommend a firmware upgrade.
