Wind direction shows question marks if light measurement is in place

[bojtospeter]

I've created a setup using my micro:bit and my weather:bit. I've set up the whole system.
I've wrote an example code (using makecode.microbit.org), which reads almost all sensor data (including the built in light sensor) and sends it over USB.

The problem is that the first measurement of wind direction is right, but after that I get three questionmarks. (https://github.com/sparkfun/pxt-weather-bit/blob/master/weatherbit.ts#L156)

If I limit the measurements to weather:bit related measurements, it works fine. Adding the light measurement ruins the wind measurement.

I've set up |start rain monitoring| and |start wind monitoring| on start, while the |start weather monitoring| is in the forever loop.
