hello everyone,
my xbee module cannot be detected by the XCTU software, so I tried to recover it, but when I recovered it an error message appeared "there is not an active bootloader in the module". does anyone know how to fix xbee pro s3b "there is not an active bootloader in the module" ?
-help me pls

google knows

thank for replying, but I've read this website, but I don't understand the steps, would you mind telling me?

If you did not understand the specially written tutorial, it is unlikely that someone will undertake to explain it again. If you do not understand any specific points - ask questions

what is the meaning of this stage
First, set RTS high and DTR/SLEEP RQ low (TTL 0V).

After that, power cycle or reset the module by sending a serial break to the DIN pin.

After that, when the device is turned on, set DTR/SLEEP RQ and DIN to low (TTL 0V).

Right now, RTS ought to be high.

End the serial break by sending the device a carriage return at 115200 baud.

The gadget transmits the Ember bootloader menu DOUT pin to 115200 baud if it is successful.

The Bootloader can receive commands at a rate of 115200 b/s.

Notably is disabling hardware flow control when accessing and communicating with the Ember 357 bootloader.

Here, 8 data bits, 1 parity bit, and 1 stop bit are used for all serial connections with the module.

The firmware for the XBee3 Zigbee RF module can be updated serially. This is accomplished by starting the XBee3 Bootloader and using XMODEM for flashing the firmware image.

is this in the wiring? if so, is the arduino rst pin and xbee rst pin on?

would you please tell me how to make this part "set RTS high and DTR/SLEEP RQ low (TTL 0V)."

That is asking you to connect those pins to chip positive ( high) or 0v ( low)
Power cycle means switch off then on again.

Using the serial monitor from the IDE , set baud rate ( bottom left of screen) .
Pressing return is the serial “ break” .

thanks for replying,
do you mean to press the reset button on the arduino uno?

No return on the keyboard
