I hava a Xbee 3 micromodule, with a XBee surface-mount (SMT) Grove development board. One Xbee is a router and the other cordinator. When I configure the router to pin hibernate (pin sleep), It turns into end device (as expected) and then enters in power down mode, turning the led lights off (sleeping mode). So far, everything working properly. But when I activate the pin 9 with 3,3 volts, the end device doesn´t "wake up" and can´t send any sensor information to cordinator. ( I have a hall sensor coupled to the router). After that, as the end device is sleeping, I´m not able to discover it in the network again, I have to put it in the USB port in my computer, and change its configuration to not sleep (becoming router again). Anyone having this problem? I´m not able to "wake up" the device again.
