CC3220SF: CC3220sf is not going to LPDS mode using (TIDC-01005) wifi door lock reference design

Part Number: CC3220SF
Other Parts Discussed in Thread: TIDC-01005, CC3220S, UNIFLASH

Hello,

I am working on CC3220sf and building my application on TIDC-01005 WIFI door lock reference design software.

As we are in a stage we need to check for the power consumption of our custom board we are observing the CC3220sf is not going to LPDS(Low power deep sleep) mode.

As i have built my application on TIDC-01005 software i have not changed any of the basic timeouts like LSI (Long Sleep Interval) which is still 500ms.

In the document TI Designs: TIDC-01005 Battery-Powered, Smart-Lock Reference Design With Cloud Connectivity Using SimpleLink™ Wi-Fi section

2.4.9 Low-Power Consumption it is mentioned as below

TI-Drivers include a power manager that puts the MCU subsystem of the CC3220S into low-power modes when the system is idle. In the TIDC-01005, the MCU enters LPDS any time the idle task is executed. The network processor subsystem of the CC3220S uses a policy called Long Sleep Interval (LSI) to increase the amount of time the Wi-Fi NWP spends in a low-power mode between AP beacons and broadcasts, which can significantly reduce the average power consumption. The maximum sleep interval allowed by default in the TIDC-01005 software is 500 milliseconds, but the actual amount of time the Wi-Fi NWP spends in LPDS depends on the parameters of the AP (for example, beacon interval and DTIM value).

In above paragraph i didn't get the point saying actual amount of time the Wi-Fi NWP spends in LPDS depends on the parameters of the AP (for example, beacon interval and DTIM value).

What is beacon interval and DMIT value? Is it mentioned anywhere in the software?

Hi Sanath,

The purpose of that sentence is to point out that the behavior of the AP the CC3220 is connected to will affect its power consumption. The parameters mentioned, the beacon interval and DTIM value concern how often the AP will send out beacons with the DTIM bit set, i.e. how often the CC3220 will need to wake up if it doesn't want to potentially miss multicast data delivered in those DTIMs.

The wiki page has some info: https://en.wikipedia.org/wiki/Delivery_traffic_indication_message

A deep technical explanation of 802.11 power save, including the impact of the DTIM on the various power save modes can be found here: https://dot11zen.blogspot.com/2018/02/80211-power-management-with-packet.html

Since the DTIM and beacon interval settings are set at the AP and cannot be controlled by the AP, it is simply something that you will need to keep in mind when performing power measurement.

Let me know if you need more clarification or have further questions.

Regards,

Michael

Hi Michael,

Thanks for the detailed information.

So according to this i need to change the flow of my code or else it will not work out because our board is not entering LPDS mode.its taking upto 20 mA continuously which means its engaging in some activity as you explained.

As our application is based on battery operation power consumption is main factor.

Any suggestions from your side on how to deal with this?

Regards,

Sanath Rai

HI Sanath,

Have you defined the USE_POWER_POLICY symbol? As explained in the design guide, by default LPDS is actually turned off, in order to allow you to use the debugger with the wifi_doorlock design. You'll need to add that to your predefined symbols in your compiler to get LPDS working if you haven't already. Please do so and recheck the power consumption.

Regards,

Michael

Hi Michael,

Thank you for the point you suggested.

That was a mistake from my side i had not seen that section in the document.I have added the USE_POWER_POLICY predefined symbol and have built the code and dumped it via UNIFLASH.

i just checked it after the changes made still its showing the same current consumption(20mA) .As per document it should show around 377 micro Amps.

i feel its still not entering LPDS.

Any further changes need to be done other than that?

i will just brief you our application.

All the basic things i have built on wifi door lock reference design like MQTT ,we are not using Bluetooth,OTA,motor and the sensors so i have disabled them.

i have added one more Button interrupt for our application along with the existing button interrupt.

one more point is the original wifi door lock reference design is built for cc3220s ,right now i am using cc3220sf. I have built the code for CC3220sf using CCS and Functionality wise our custom board with cc3220sf is working fine without any issues. Only issue we are facing is that its not entering LPDS and consuming 20mA.

Anything Hardware changes need to be done? and is there any way to check whether its going to LPDS or not?

i will attach the configuration file for your reference.

Hi Sanath,

Have you tried running the door lock code on a CC3220SF launchpad in addition to your custom board, and seeing if the launchpad also doesn't seem to enter LPDS? Isolating the cause of the problem will be key, and knowing if it's in the door lock code or something to do with your hardware will be very useful.

Regards,
Michael

Hi Michael,

I have run my code in cc3220sf launch pad but i have not checked whether it's going to LPDS mode or not.

I will check that and update you.

While checking the power consumption in cc3220sf launchpad i need to isolate the emulator part right? I need to check the power across cc3220sf ?

Regards

Hi Sanath,

Yes, isolating the emulator is required. See section 3.2.3 of the TI design guide for test setup to replicate our power measurements on the launchpad setup.

Hello Michael,

We tested the same set up in CC3220SF launchpad .Even here its taking 20mA. there is no difference . We made the setup same as mentioned in the document powering only cc3220sf and serial flash.

After that i made one more test

In my application i am using UART for communication with another host controller for our application.

for the test i just removed it(commented the whole uart part) and after that when i dumped the code the current consumption reduced to micro amps .that means the UART is not allowing it to go to LPDS.

But for my application UART is one of the main feature .

As i just read about LPDS that

During LPDS the internal GPIO module is powered off, and special periphery logic is used instead to detect the trigger and wake thedevice. No GPIO interrupt service routine will be triggered in this case (even if an ISR is configured, and used normally to detect GPIO interrupts when not in LPDS). This function can be used in lieu of a GPIO ISR, to take specific action upon LPDS wakeup.

Only one GPIO {2,4,11,13,17,24,26} can be specified as a wake source for Shutdown.

So how can i use GPIO interrupts and UART in my application in LPDS mode?

If not LPDS we can use sleep mode where it wakes from sleep whenever an interrupt hits unlike LPDS where it wakes only on network interrupts ,some chosen GPIOs and LPDS wake timer it seems.

Regards

HI Michael,

Here is a update regarding LPDS.

As i mentioned in my earlier post after i commented out UART for the meantime the cc3220 is going to LPDS

Yesterday i used GPIO13 to trigger the wake up from LPDS ,there inside that callback function i again disabled the policy by using Power_disablePolicy(); function and then i used the other GPIO interrupt where after the completion of task inside that ISR i enabled the policy again using Power_enablePolicy(); so that worked out for me for using GPIO Interrupts.

But the concern is using UART for me . whenever i initialize the UART in the beginning the CC3220 is not going to LPDS.

after that I tried to do the same thing where i disabled policy by Power_disablePolicy(); when GPIO13 is triggered and then initialized UART after that i transmitted data using uart_write()function and then enabled policy using Power_enablePolicy(); but here its not going to LPDS again.

How to use UART in LPDS mode i am confused now?

Regards

Sanath

Hello Michael,

Here is an update about LPDS.

The issue was with UART receive call back which was not allowing the MCU to go to the idle state that's why its was not entering LPDS mode i guess.

i disabled the receive call back initially and enabled only when i require it and now its going to the LPDS mode.

The current consumption is low now,we will do further testing.

Thank you for the support.

Sanath
