CC2652PSIP: Coordinated Sampled Listening (CSL) feature for Synchronous Sleepy End Device(SSED).

Hi,

CSL should be enabled by default: https://github.com/search?q=repo%3ATexasInstruments%2Fot-ti+csl&type=code

And CC2652PSIP is also a supported board: https://github.com/TexasInstruments/ot-ti/blob/release/thread-1.3-certification-support/script/build#L60

Thanks,
Toby

Hi,

Thanks for the reply. Can I use the temperature sensor example for checking the CSL configurations?.  I have set the following values in the temperature sensor program. But working of the CSL could not be verified.

#define OPENTHREAD_CONFIG_MAC_CSL_RECEIVER_ENABLE 1
#define OPENTHREAD_CONFIG_MAC_CSL_TRANSMITTER_ENABLE 1

#define OPENTHREAD_CONFIG_MAC_CSL_AUTO_SYNC_ENABLE 1
#define OPENTHREAD_CONFIG_MAC_CSL_MIN_PERIOD 10 //millisecond
#define OPENTHREAD_CONFIG_MAC_CSL_MAX_TIMEOUT 10000 //seconds
#define OPENTHREAD_CONFIG_CSL_TIMEOUT 100 //seconds
#define OPENTHREAD_CONFIG_MAC_CSL_DEBUG_ENABLE 0
#define OPENTHREAD_CONFIG_CSL_RECEIVE_TIME_AHEAD 320 //microseconds
#define OPENTHREAD_CONFIG_CSL_MIN_RECEIVE_ON 356 * 16

#define TIOP_CONFIG_POLL_PERIOD    60000

#define TIOP_TEMPSENSOR_REPORTING_INTERVAL 60000

The energy trace graph is shown below. But CSL pulses are not found.

Is it joined to a Thread network?

yes

I'll try to reproduce this on my end.

Please expect an update in 3 business days.

Sure sir, take your time. Thank you.

Hi Sudheesh U G,

Wanted to update you, I have not been able to reproduce the issue. Will try again next week.

ok

Hi Sudheesh U G,

In our next release of Thread (scheduled for end of April), it will be on https://github.com/TexasInstruments/ot-ti/tree/main and more easily enable support for CSL (through "TIOP_POWER_SSED"), including power measurement.

I recommend to use this once it is released, as it will contain latest updates for TI-OpenThread.

Thanks,
Toby

Hi Toby,

Thank you for the support.
