+xThey are very different devices and you can only use one at a time in SkyDemon. I can't think how one could possibly use them both at the same time, as they both provide positional data and they both include ADS/B traffic so there would be duplicates reported.
Thanks Tim.
Think I confused myself on this TBH!
Now that Uavionix are fitting a barometric sensor and replacing existing units, I will leave the ATT20B as is, so will be transmitting ADS-B out and use the PAW through SkyDemon as a Traffic Awareness aid.
