Other Parts Discussed in Thread: CC3200

Hi Friends

In CC3200 data sheet Following line is mentioned.

"Idle Connected (MCU in LPDS): 695 μA @ DTIM = 1"

Questions

  1. "It mean the MCU is in Deep sleep and is TCP connection is connected with AP" is it correct understanding ?
  2. TCP connection is connected so if any application packet received can It generate event to Wake up Device from Deep sleep and serve that received packet ?
  3. In this mode can Device wake up at specific time of interval and send periodic data ?
  4. If device remains in same mode what would be life of device with two AAA @ 1150mAh batteries ?

Please suggest your answer, based on that I can go ahead.

Thanks,

Jignesh

    Hi Jignesh,

    Let me answer some of your queries.

    1. Yes, Idle connected (MCU in LPDS) means that the APPs-MCU is in LowPowerDeepSleep while the device continues to be connected to the AP (can be with an active TCP connection).

    2. Yes, any activity on the network can wake the APPs-MCU from LPDS.

    3. Yes, the different sources that can wake the APPs-MCU from LPDS are waketimer, GPIO and network activity. So you will be able to configure a timer to send data periodically and also wait on a packet to be received on the network.

    Best regards,
