Latest EoRa PI Foundation --Receiver with WOR, puts LoRa module in listen mode, wakes deep sleeping ESP32
/*
Claude's version 112 Latest code with J-K Flip-Flop (74HC73) untested. Part on order. Code is
a works in progress. Cold boot is working, repeating cycle after cold boot is not working,
DIO1 signal is too fast; this is where the 74HC73 comes in to toggle and hold the wake up pulse
from the LoRa radiop module. DIO1 signal is used for Wake on Radio, puts radio into listen
mode and wakes Deep Sleeping ESP32 using external wake up..
Project uses Ebyte's, provided "boards.h" board configuration and "utilites.h" pin assignments.
Coded by Claude with Design and prompting code execuyion. Troubleshooting provided by Claude
and William Lucid.

Modification?
Does this need modification to use with DeepSleep.ini?
void OnRxDone(uint8_t *payload, uint16_t size, int16_t rssi, int8_t snr) {
Serial.println("WOR wake triggered: Packet received");
// Convert payload bytes to String
String packet;
for (uint16_t i = 0; i < size; i++) {
packet += (char)payload[i];
}

* @author Bernd Giesecke (bernd.giesecke@rakwireless.com)
* @brief Low power example for ESP32 and SX1262
*
* This examples shows LoRa P2P communication with a ESP32 using the
* sleep function of the ESP32 to lower the power consumption.
* The ESP32 goes into sleep after initializing the SX1262 to listen
* using the RxDutyCycle mode. In this mode, the SX1262 is sleeping as
* well, only waking up to check if any preamble signal is detected.
