I have used it between a charger and several bms boards. Each board sent a packet of 8 bytes long, which were the 8 voltages of that bms module's 8 batteries. There were 6 modules just blasting their 8 bytes randomly and each ignored each others 8 bytes. The charger would pick up all the packets. No problems with noise and no missed packets (i dont think). And the data was never corrupted. You just use a little 8 pin $1 part along with the dspic CAN module.
Sounds a bit like MQTT, which I've been using for a home automation project. Though MQTT needs a central broker to receive published messages from devices and to distribute them to subscribed devices. So probably not that close now that I think about it. >.<
Making do with a Honda Civic. Tesla Model 3 reserved. Still kinda want an SVX for fun, though.
