IGPSport SR30 freeze with Karoo 2

After connecting to K2, the IGPSport SR30 radar only works for 10-15 seconds, then it loses connection. The radar doesn't respond to anything, it freezes. The only solution is a reset.

Both K2 and IGPSport SR30 radar have the latest updates.

This is not a problem with my unit, as I tested another IGPSport SR30 radar on a different K2 and the problem still persists. It seems to be a software bug. But it's hard to tell at the moment which side the problem is on (K2 or SR30?)

Resetting the devices to factory settings does not solve the problem.
I found on intermet that previously this radar works fine with a K2. 

Does any one face such issues? 
Thanks in advance for your response.
