We currently have PLATFORM_IDs such as PLATFORM_BORON, PLATFORM_XENON and PLATFORM_ARGON allowing us to differentiate between the different 3rd gen particle device. Is there a way I can differentiate between Boron 2G/3G devices and Boron LTE-M device (i.e. are there PLATFORM_BORON_2G3G and PLATFORM_BORON_LTEM equalivents)
Hence I’d say no, there is no platform ID for that.
I guess you’d have to detect the technology at runtime via a Cellular.command(), but I’d have to leave that to someone else.
