Bad optflow health - HereFlow

Hi,
I have a HereFlow sensor connected to CAN1 port in Pixhawk4 with the official firmware 4.1.2. I set up the relevant parameters and I’m unable to get any data from the sensor. I downgraded to 4.0.3 and it worked fine, and when I upgraded back to 4.1.2 it stopped working. Any ideas?
Parameter files for Copter 4.1.2 and 4.0.3 are attached.

Thanks,
Lev

I used the SLCAN tool in MP in order to detect the HereFlow while using Copter version 4.0.3. I’m attaching a photo where it is possible to see the HW/SW version and other info. After upgrading to 4.1.2 the SLCAN failed to recognize the device and the devices table is empty.
Any suggestions? I tried to update the sensor’s firmware but it seems that it’s already on the latest version.
