i'm using the XBee-PRO 900HP boards with the Java library.
The xbeeDevice.open() issues the following exception: "com.digi.xbee.api.exceptions.InvalidOperatingModeException: Could not determine operating mode".
I'm sure that the COM port is right and that the Java code is correct ( i tested it also on XBee 868 boards), and i tested it on both Windows and Linux, but i'm not able to use these boards.
I tried to change the API mode with or without escapes but I obtain the same error.
The only way is to open the XCTU tool, let him to discover these XBee-PRO 900HP boards, and then i can run my java code on the boards without any error; but if i power off the modules and then i power on them, they don't work.
I also tried to load default firmware on the board, but nothing change.
How can i solve this problem?
