cc2530znp end device power

I am using the cc2530znp mini kit. In my application i have a coordinator and an end device.

the end device joing to the network and go to sleep mode for a long time. the power consumption is 5uA. The problem is if I turn off the coordinator,  the end device consumption is big, about 12mA. How can I keep the end device in low power consumption if the coordinator is off or in a long distance? I try to setPollRate to 0 but the problem persist.

I also try to call RADIO_OFF() while the end device is out of range but the consumption is 1mA and not 5uA how it is on sleep mode

    When the coordinator is off, the device will start to send beacon signal periodically and the duration between two beacons is controlled by BEACON_REQUEST_DELAY. You should enlarge this duration.

    Hi YiKai,

    Thank you for your response. I could not find this constants in the code from examples. I had compile a new version of zStack with this change but the problem is the same when the coordinator is off the end device try to re-join the network and the consumption go up.

    One solution could be call RADIO_OFF() macro and each some time (i.e: 10 minutes) call RADIO_ON() and try to reconnect. the problem is that when I call the radio off the consumption go from 5uA in sleep mode with RADIO_ON to 1mA in sleep mode with RADIO_OFF. I do not know why.

    Regardds
