CC2530: Power conserve problem in end device!

Piaozhun
Expert 2620 points

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK,

Hi everyone.

I have release smart system with coordinator and end device(use Battery) but they have many issues.

I have some problems are as following:

1. After coordinator is power off and power on , end device can't rejoin to coordinator soon.

2. In 1) , power conserve in end device is high.

I want to lowest power conserve of end device with coordinator's status and coordinator communication with sleeping end device anytime.

Please help me.

Thanks in advance.

    Which Z-Stack version do you use? Do you enable NV_RESTORE on your coordinator and end device?

    Hi YiKai Chen.

    Thanks for your reply.

    I have use z-stack 2.5.1a and enable NV_RESTORE.

    Hi YiKai Chen.

    I gonna append my project status.

    To save power of end device , I have use following code.

    #if !defined(ZDO_COORDINATOR)
    if ( events & SAMPLEAPP_WAIT_TOUCH_MSG_EVT)
    {
    delay1ms(10);
    InitKey(1);// GPIO Interrupt Enable (RX Pin of UART)
    halSleep(1 * 1000);//1s
    InitKey(0);// GPIO Interrupt Disable
    osal_start_timerEx( SampleApp_TaskID, SAMPLEAPP_WAIT_TOUCH_MSG_EVT, 100);//g_nWakeTimeOut);
    return (events ^ SAMPLEAPP_WAIT_TOUCH_MSG_EVT);
    }
    #endif

    I didn't use "POWER SAVING" because I did think that "power saving" not run well.

    I want to your opinion.

    Best regards.

    Z-Stack 2.5.1a is obsolete stack. I would suggest you to use latest Z-Stack to fix rejoin issue. For end device power consumption, you should enable POWER_SAVING to conserved power.

    When coordinator is power off,end device is able to conserve power?

    I hope your reply.

    Hi YiKai Chen.

    If it use POWER SAVING, What is value of POLL RATE to reduce power consumption?

    Please help me.

    It will automatically stop poll rate

    Hi,

    Z-Stack 3.0.1 for CC2530 uses a round-robin style super-loop to execute pending tasks within the system. If you are unsure what this means you can Google around for more information. The important part though is if you have the POWER_SAVING flag included in your build, when there are no pending tasks in the system (i.e. none of the task 'events' variables have any bits set in their bitmask), the OSAL layer will automatically put the device into low power mode. You can think of the poll rate like an "event" in the system. If your poll rate is set to 1000, the device will set the corresponding bit in the 'events' flag for the NWK layer every 1 second and this will wake up the device from power saving mode to send a data poll, then it will go back to sleep until the next event. So, if you extend your poll rate, you device will wake up less often and therefore it will save more power.

    If your end device is a direct child of a coordinator (or router for that matter) and you were to power that coordinator/router off, the end device would "Orphan" as soon as it tries to poll its missing parent and then it would start searching for a new parent, this is the intended behavior of an end device that loses its parent device in a Zigbee network.

    Hi Jason.

    Thanks for your reply.

    I have understand fully your opinion.

    Sorry, I have one question.

    If coordinator or router is power off,How is power consumption of end device that find itself parent?

    Best regards.

    In Z-Stack 3.0, ZED would only send one beacon request to find parent. If it cannot find new parent to join, ZED would go to sleep mode which only consumes few micro Amps and application can do rescan later according to your own decision.

    Hi YiKai Chen and Jason.

    I have port my project with z-stack 3.0.

    And I have use "POWER SAVING" and "POLL RATE = 1000".

    Then Standby current of my board(use CC2530 + RFX2401C) is about 1360uA.

    I have start from Generic App project.

    Please help me.

    If you set POLL RATE = 10000 and check current consumption during device not polling, what current consumption do you see?

    Hi YiKai Chen.

    Thanks for your quick reply.

    I have forgot that enable HAL_PA_LNA.

    I have enable HAL_PA_LNA and set POLL_RATE = 1000, standby current is 465uA.

    So I set again POLL_RATE = 10000,standby current is 192uA.

    Hi YiKai Chen.

    Sorry my mistake reply.

    I have test wrong value of standby current.

    Either POLL_RATE = 1000 or POLL_RATE = 10000 , Standby current is 189uA.

    It sounds reasonable. To further reduce the sleeping power, I think you should check your HW.

    I have port my project from z-stack 2.5.1 a to z-stack 3.0.1.
    But End device can't join to coordinator.
    End device don't send beacon request too.

    I hope your opinion.

    Yes. YiKai Sir.
    I have put last of zclGenericApp_Init().
    bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION | BDB_COMMISSIONING_MODE_NWK_STEERING | BDB_COMMISSIONING_MODE_FINDING_BINDING | BDB_COMMISSIONING_MODE_INITIATOR_TL);

    This should make ZED send beacon requests. Do you have button on your ZED? If so, can you use button to trigger bdb_StartCommissioning instead of putting it in zclGenericApp_Init

  • 0 in reply to YiKai Chen
    Expert 2620 points
    I haven't button in my board.
    So I tried as following but result is same.
    In zclGenericApp_Init, I put osal_start_timerEx( zclEasenLock_TaskID, EASENLOCK_START_BDB_COMMISSIONING, 2000 );

    ....

    if ( events & EASENLOCK_START_BDB_COMMISSIONING )
    {

    bdb_StartCommissioning( BDB_COMMISSIONING_MODE_NWK_FORMATION |
    BDB_COMMISSIONING_MODE_NWK_STEERING |
    BDB_COMMISSIONING_MODE_FINDING_BINDING |
    BDB_COMMISSIONING_MODE_INITIATOR_TL );

    return ( events ^ EASENLOCK_START_BDB_COMMISSIONING );

    Between Coordinator and end device was connected.

    In the end device is sending data request packet to coordinator.

    So When I press button,coordinator send "ABCDE" packet to end device.
