  • Air Quality Wing with external Bluetooth antenna

Hi Jared,

A while back in the AQW docs, I noticed that there was a photo of an antenna (Bluetooth) being used with your enclosure that probably had a particle_xenon board. I have a BT antenna for my AQW enclosure that I plan to use with AQW.

In reviewing Zephyr code, on power-up, board_particle_xenon_init() forces PCB antenna selection. What is the best way to select the external antenna? Any code you can share? Thanks.

Also, Are there any precautions I need to take whilst hooking up an antenna, e.g. power down AQW?

    Hey zpm1066

    You’ll need to change that function to external_antenna(true). I don’t recommend hot swapping antennas. Make sure everything is powered off when attaching/detaching.

        Thanks. I was going to change external_antenna(false) call from false to true but then decided to look for an option that didn’t require a change in the Zephyr repo itself.

            zpm1066 you can take that function and call it elsewhere in your code once it boots into your main()
