I have a system which is powered by a relay activated by a xbee module. The system is on battery, so I need to make a cyclic sleep on the xbee card to save power.
The difficulty is that I want to make RS232 connection when the system is powered. the problem is that the xbee stay in cyclic sleep while the rest of the system try to communicate.
I don't know how to proceed to make it.
I've tried SM=5 and many things but it doesn't work..
Do you have any simple idea to keep the xbee end device activated when I need?
I use XCTU to configure it.
Do I have to make an electrical connection on a special pin to leave on request the cyclic sleep mode?
Thanks for your answers,
