CC2530 sleep mode

hi everyone,

I am trying to use RSSI to work, I would like to ask whether the sleep mode indicates that there is small or even no transmitted signal.

I get stuck in this problem. Thank you so much!

    There is no TX/RX under sleep mode.

    So, it means that if the module is in sleep mode, then another sensor cannot receive any signal strength from that particular node ????

    Then, can it be waken up externally and internally????

    Yes, you can't receive any signal strength from a sleeping node. A ZED will wake up periodically by setting POLL_RATE, which will make the ZED polling its parent to see if there is anything needed to process. This is internal wake-up. If you want external wake-up, you can use GPI interrupt to wake up ZED from sleep mode and do TX/RX.
