Update of the firmware makes that my project doesn't work

XBee & XBee Gateway XBee - Zigbee

I’m doing a project using the xbee3 Modules. When i test the project with the oldest firmware Version (1003) the project Works perfectly. But when the Module has a new firmware (100A or 1009) the project doesn’t work at first. What i have to do is to short Circuit the Tx with Rx of the Module for a short time and begins to work. Can someone explain me why does it happen?

Thanks

That would have to be something in your code that is causing the issue. Are you able to send and receive data with the new firmware not using Micro Python?
