Great New LoRa Chip
But Meshcore won't support SX1302 or other multipath chips any time soon...
Noodling around on the internet I see there are much enhanced versions of the popular SemTech SX1262 chip many of our devices use for LoRa communications.
These new chips, the SemTech SX1302 & SX1303 can process 6 concurrent channels, have better error correction to fix up otherwise bad packets of data, and other features. The SX1303 supports Fine Timestamp and network positioning based on time difference of arrival (TDOA). See Waveshare’s site for a nice pinout and details of these features.
Looking then for what devices we could use that leverage the SX1302, I found this statement from a key Meshtastic maintainer: “Meshtastic uses RadioLib to interface with the radio, and RadioLib has no real support for the SX1302 at this time.” at GitHub Discussion. Bummer, we gotta wait…
Actually looking further into this (see GitHub Discussion) this is not likely to happen anytime soon, the base code is not available, and the exposed drivers aren’t easily wrapped for RadioLib.
That led me to look up RadioLib (see jgromes.github.io/RadioLib/), “Universal wireless communication library for embedded devices.” This is where you can then see upcoming devices, ones that are getting worked on anyway.
