External Antenna

Thanks so much bko.

You said:

You select the external antenna in software on a Photon and the setting is “sticky” so that the Photon will try to use the external antenna from that time on.

It means that if I put in my program:

STARTUP(WiFi.selectAntenna(ANT_EXTERNAL));

  1. After that, not matter if I upload another program from particle portal (it means load and reset the photon) continue to receive from external antenna?

  2. On the post: Add external antenna to chip-antenna core? you found the following question and answer.

if I remove the L1 inductor, does that disable the chip antenna? I’d like to be able to use either the uFL or chip antenna

You can’t use both, sorry. The antenna matching circuit only supports one or the other.

The point is:

  1. First I run the program (with internal antenna wifi conn), and the program set External Antenna
  2. I install my photon in a place that has no signal for internal antenna.
  3. Perhaps, I have to load a new version of program to it. (it implies photon reset). I need, when the photon try to connecto to wifi use the external antenna.

Thank you very much,
