Well this weekend I spent much of it hacking Python and ReactJS… teaching a PocketBeagle SBC some new tricks. These devices are being used in RFID terminals that take card reads from UHF RFID scanners, and transmit them back to base over APRS/AX.25.
I added the ability to associate a tag EPC with a competitor number. Over WiFi, they now send that number to a Pimoroni Interstate75W using UDP multicast, to flash up on a RGB LED display.
A ReactJS web interface allows for updating those associations, and observing status in real time. Also sending competitor numbers over packet by manual entry.
I'm really pushing the limits of APRS: 60 characters is not a lot. I might be dusting off my 6LoWPAN over AX.25 ideas yet.
