There is a socket on the AIO v5.0a PCB for a XIAO ESP32-C3 to create a WiFi AP for wireless modules to connect & receive AOG PGNs. The PGNs received by the Teensy via Ethernet, are forwarded by the Teensy via serial to the ESP32, which in turn broadcasts them via WiFi. Modules that receives the wireless PGNs reply back to the ESP32 which forwards the replies back to the Teensy via serial, then the Teensy via Ethernet back to AOG.
