I have two XBee3 SMT Grove Development boards. When I run XCTU, they don't show up. I suspect that they are running MicroPython flash programs and won't connect to the PC. Is there a 'master reset' or some other way to stop them?
Module 1: In XCTU, when I selected the 'Device not found?' link, I tried all the options, including the Recovery Tool. Recovery Tool appeared to work. It uploaded the firmware, etc but it still isn't recognized by XCTU.
Module 2: In XCTU, it said Could not find any device in port COM13 > Error initializing XBee device parameters > Port already in use by other applications. (There are no other applications, except maybe the microPython one running on the development board. I changed the serial library to Alternative, then I tried the Recovery Tool but got a message stating "Error opening the serial connection. > Port name - COM13; Method name - openPort(); Exception type - Port Busy.
I'm using a Windows 10 computer, XCTU 6.5.1, my development board's firmware has been updated in the last month, the modules have connected to XCTU in the past, I've been working my way through the Digi MicroPython Programming Guide.
