Why is XBEE3 continuously resetting after programming?

We have developed a custom battery powered board that we are programming with the XBEE SMT Grove Development Board. After programming the XBEE3 resets about every 10-15 seconds. When connected to the XBEE SMT Grove Development Board it doesn’t reset but stand alone it does. Are there pull up resistors that are required on any of the programming lines for normal operation?


I would suggest looking at the hardware reference manual at https://www.digi.com/support/productdetail?pid=5637&type=documentation and the interface board schematics at https://www.digi.com/support/knowledge-base/interface-board-schematic
