Hey @casm that’s a great application! The Photons are especially exciting because they have both an onboard antenna and a u.FL connector for attaching more powerful external antennas. They also have an RF switch that allows you to choose between the two, so you could include lines in your logic that automatically default to whatever antenna has the stronger signal!
Thanks for the feedback and the kind words! The Core is now out of active production so we only have a limited number of units remaining, but let us know if you have continued issues with the Cores on hand. We may still have some u.FL Cores in stock if you think it warrants replacement.
