Here 3+ FW update on Mini Carrier Board

Here GPS
1

Hello,
I am using a Cube Yellow with a Mini Carrier Board and Here 3+ as a GPS. To update the firmware, you have to set the CAN-passthrough via the slcan setting in Mission Planner. Since the Mini Carrier Board only has a CAN2 Port to plug the GPS in, I did that. Now i tried to set CANpassthrough using the slcan connection, but the Here 3 GPS only shows up when using MAVlink-CAN2. I think the GPS should be connected to CAN1, but as mentioned, the Mini Carrier Board uses the CAN1 only internally for Ardupilot (which shows up in the slCan UI).

Is there a way to upgrade the firmware using the CAN2 or only CAN1? And if is only possible using CAN1, is there a different way to upgrade the FW?

PS: My SW Vesion is 1.3.4AB183F6 and I am not sure if this is the most recent version, since there are no listings online.

I have tried with Cube Orange+ on mini carrier board facing similar problem with Heere3+.

I can able to see the parameter of Here3+ but there is no pass through or GNSS configuration parameters as mentioned in the Wiki documents.

Due to couldn’t configure the Pass through function Here3+ is not connecting with U- centre ublox software.

As per Here3+ specifications constellations is GPS,GLONASS and Beidou,but i think its only working with GPS and GLONASS and not with Beidou satellite.

This i have monitored in HERE+ base station.

@enginuity-cansat i also having same SW version.

@philip Here3+ GPS will get RTK fixed if base station is ZED-F9P?

I was waited about 60 min and still Here3+ status is RTK Float only and never got RTK Fixed!

That’s not good, but i think it should work as well. Thank you for the quick reply

Can1 or CAN2 can be used.

I was using CAN2 since mini carrier board has only CAN2 port.

As per above mentioned here3+ manual i was tried to connect with Ublox u center.
Here3+ internal parameters doesn’t have passthrough option 0,1 and 2 for various here3+ configuration as mentioned in the manual…
