Are there plans to allow Xenon’s to be used in a BLE-only mode?
I’ll tell you why I’m asking. I’d like to add sensors that will be mostly off. for example water-leak sensors. I will not want to pay monthly per-device for these sensors so am instead looking for ways for them to speak to a backhaul mesh network without being mesh nodes themselves.
I’m considering the ESP32, but it only does BLE 4.2 (which really is probably fine). When looking for chips that support BLE 5 the most common are the nRF528__. It’s possible to pick up some non-particle devboards in the $5-ish range, but particle.io boards are almost certainly easier to deal with.
