can we loop back TX and RX in xbee withou t using microcontroller?

You didn’t mentioned which XBee module are you referring to.

Although, answer to your question will be Yes for all modules. Just use a jumper wire and short UART In and Uart Out pins of modules.

In Zigbee modules, even this trouble can be avoided by changing CI parameter to 0x12 and data transmitted by that module will be loop backed to it.

using jumper wire wont short circuit the module?
i am using ZB24-Z7WIT-004.

You can short Tx and Rx pins i.e. pin 2 and 3 of your module without any issue.

It won’t short circuit. We are neither involving VCC or any pin with high voltage not GND.
