When I issue the ND command, the Xbee module becomes unresponsive for the time of NT. I need to wait for ND answers with nodes found. But lets say the ND command is ongoing and the master MCU just went ON and tries to send something through uart to the Xbee module. There will be a timeout. Is it possible to ask the Xbee module either he is in ND state? Or is the only option to restart the Xbee module? Or is reset not a solution as well?
I would appreciate all help.
