I can’t connect the device in a u-blox center for trying to update the firmware.

I have no idea how you arrived at that pinout, but the Here 3+ is a CAN device and must be connected to the CAN port via the instructions from CubePilot.

Hello yuri Yes, the cubepilot have 2 connectors of 4 pins and the pixhwak have 1 of 6 pins and 1 of 4 pins for gps and i2c port and i use this manual instructions for find the order of the pins. And exchange the connectors.

Again, I don’t know where you found that info, but it is patently incorrect.

The Here 3+ is a CAN device. It gets wired to the CAN port. Here is the pinout, straight from the manual that I linked.

The following note applies, indicating that only CAN 1 needs to be connected:

Note: Current firmware only support CAN 1 ,CAN 2 is not supported. Dual CAN will be enabled in a future firmware update.

Just to make things as clear as possible, the GPS port is simply SERIAL3 laid out to make connecting some common GPS/compass modules very simple. The Here 3+ is not a serial/I2C device and is not compatible with that port on the Pixhawk.

Instead, it must be connected like so:

Follow the manual instructions for parameter settings, firmware updates, etc.
