I am working on a project that currently uses two DWM1000’s. One is connected to a Raspberry Pi 3 B+ as the tag and one is connected to an Arduino Due as the anchor. Eventually I will expand to 4 Arduinos for the anchors.
My question is, how do i communicate between the Pi and Arduinos? I can’t find any libraries online that are cross-compatible like this. I have also never worked with DWM’s before so any help that can point me in the right direction is much appreciated.
Be careful using the uart. The Pi isn’t 5 volt tolerant (at least they didn’t used to be I’ve not checked the latest version) and the Arduino outputs at +5V.
Assuming you don’t need high speeds a series resistor is probably good enough to drop the current to the point where the internal protection diodes can cope. Not great and not something you’d want to ever do in an end product but good enough for testing.
I’ve never heard of UART so after doing some research on my own, it seems like this would require a wired connection between the Arduino and the Pi? Am I missing something here? I want the communication to be wireless.
