In sleeping mode of pin controlled I am attempting to use I/O Line passing with Xbee S2C. While linking with XBIB-U-DEV It’s functioning well,
But the problem is with standalone mode , when I use Xbee in this mode the sleep mode of pin controlled stop functioning while on other hand I/O line passing still functioning.
In my opinion this problem occurs when I joined its UART to some other module like NodeMCU module
and with its removal it starts functioning. Please lend me a hand to sort out this problem.
