Oops. So, it never tried for longer than 15 minutes with that sketch because the watchdog doesn’t get “fed” while it’s waiting for the internet and it “bites” (ie, forces the board to reset) after 15 minutes. But 15 minutes is still a pretty long time to wait.

After the first connection in a new location, it should connect much faster in subsequent attempts. That is, if you can convince it to connect at all. From your log it doesn’t look like there’s anything wrong with the board programming; the XBee is just really, really convinced that it cannot connect to the network. Can you go back and try bypass mode again with both the USB *and* the LiPo plugged in and post that log? The trick that @neilh20 recommended is basically to send the XBee the command you would have used if you were in bypass mode but without actually entering bypass. Of course, based on all the manuals, that *shouldn’t* work, but if it’s stupid and it works…

To connect the XBee3 with XCTU you do need another adapter or development board. The XBee3 TH development board is probably the easiest way to connect them (https://www.digi.com/products/models/xbib-cu-th) because it uses USB-C to provide enough power and also separately breaks out the USB direct pins for easy plugging in straight to the SARA module. If you’re going to be using a bunch of XBee3’s, just spend the $70 and make your life a lot easier. If this is a one-off, I think there are ways to update “over the air” but it’s not as easy. To just check your firmware version you can run something like this on the Mayfly:

#include <StreamDebugger.h>

void setup() {
  // Set console baud rate
  Serial.begin(115200);
  delay(10);

  // Set XBee module baud rate
  Serial1.begin(9600);

  // Get into command mode
  delay(1500);
  Serial.println('+++');
  Serial1.print('+++');
  while (!Serial1.available()){}
  while (Serial1.available()) {
    Serial.print(Serial1.read());
  }
  Serial.println();

  // Sometimes it "forgets" to answer requests for versions, so we'll try 5 times
  for (uint8_t i = 0; i < 5; i++) {
    // Get the Digi firmware version
    Serial.println('ATVR');
    Serial1.println('ATVR');
    while (!Serial1.available()){}
    while (Serial1.available()) {
      Serial.print(Serial1.read());
    }
    Serial.println();

    // Get the u-blox firmware version
    Serial.println('ATMV');
    Serial1.println('ATMV');
    while (!Serial1.available()){}
    while (Serial1.available()) {
      Serial.print(Serial1.read());
    }
    Serial.println();
  }

}

void loop() {
}

#include <StreamDebugger.h>

void setup() {

// Set console baud rate

Serial.begin(115200);

delay(10);

// Set XBee module baud rate

Serial1.begin(9600);

// Get into command mode

delay(1500);

Serial.println('+++');

Serial1.print('+++');

while (!Serial1.available()){}

while (Serial1.available()) {

Serial.print(Serial1.read());

}

Serial.println();

// Sometimes it "forgets" to answer requests for versions, so we'll try 5 times

for (uint8_t i = 0; i < 5; i++) {

// Get the Digi firmware version

Serial.println('ATVR');

Serial1.println('ATVR');

while (!Serial1.available()){}

while (Serial1.available()) {

Serial.print(Serial1.read());

}

Serial.println();

// Get the u-blox firmware version

Serial.println('ATMV');

Serial1.println('ATMV');

while (!Serial1.available()){}

while (Serial1.available()) {
