Unable to pair Here4 with CubeOrange+ running on PX4

First of all, I would message Mathworks and ask if there is a chance that they are supporting 1.15 or 1.16 now or soon.

In the meantime, we’ll have to figure out what the problem is. Before we do so, can you check that you have Here 4 updated?

And are you connecting it via CAN or Serial+I2C?
