CC1352R: CC1352P1 TO CC1352R sleep/wake mode

jday de la calle

Part Number: CC1352R

my idea: each time the launchpad receives the msg=1 via the usb serial, it sends a message to wake up the sensor tag. when it receives msg= 0 via the serial link, the sensor goes into sleep mode.

1- how can I transmit a message from the cc1352p1 to the sensor?
2- dynamically; how to wake/sleep the sensor tag when the launchpad receives 1 or 0?

Hi,

To receive the msg over the air, the sensor tag needs to be in RX. Please check the wake on radio example in the SDK.

The Readme for the wakeonradiorx example describes the duration where the receiver needs to be awake in order to not miss a packet and also the modifications on the TX side necessary.

From the description, it seems like you would use the wakeonradiorx and tx examples to wake the radio up.

To understand the use of UART and replace the button press with a UART message, look into the UART examples in the SDK and make the necessary modifications.

stop building while compiling the project "wakeonradiotx..."

Hi jday,

As the error message suggests, you need the FREERTOS_INSTALL_DIR to be defined. The likely cause of this error is that FreeRTOS has not been installed. Please download FreeRTOS from https://www.freertos.org/.

And then follow the steps mentioned in the TI drivers quick start guide in the Build and download project section.
https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_6_10_00_29/docs/simplelink_mcu_sdk/html/quickstart-guide/tidrivers-quick-start.html#build-and-download-project

If you want to quickly prototype, use a TIRTOS project, this error would not block you.

Also, here is the link to documentation and examples for the latest version of the SDK you might find useful.

a question: the launchpad CC1352P1 can wake up the sensor CC1352R when it sleeps ?

I can't send a message to the sensor for falling asleep

As mentioned before, to be able to send a message over the air from CC1352P1 to CC1352R1, you would need the CC1352R1 to be in RX, it cannot be asleep. So, wakeonRadio example's Readme documents the logic used there to allow the RX device to sleep for as long as possible before waking up. Please go through that Readme.

it is possible to send the sleep duration to the CC1352R1 as a message ?

this duration is variable.

Hi jday,

You can send a payload to the device. How you use this payload is up to your application logic. If you are talking about wake on radio example in particular, then no it is not possible. But if you build an application which waits on one sleep statement, you probably can have a payload dictating the sleep times.

what are the steps to build this application ?

The application development is left to you. Please use our software examples as a reference and also go through our SimpleLink academy. We provide software examples as the example applications to use various features of the device. But the final application development is left to you.
