Hi, I have the next configuration on sleep mode on Xbee XR 9000 RF:
SM 5
SP 64
ST 1F4
WH 64
I’m not using API mode
we have 21 nodes that communicate with one Gateway (it doesn’t sleep) with point to multi point communication.
When I have to transmit some data, I wake the xbee with a pulse low and then I transmit data to a Gateway and works fine, because the pulse it’s so short the xbee wake up for ST time. But after few days or weeks the xbee is getting block, it doesn’t answer any command through UART, it doesn’t send anything to Gateway and it doesn’t receive anything from Gateway, the only viable solution is to reset the xbee taking off the power supply.
What is to solution we can take to avoid resetting the nodes??
