CC2652P7: Which method is the most power-efficient for a thread chip (RCP)?

Which method is the most power-efficient for a thread chip (RCP): pulling down the reset pin, or entering the ot-ctl thread stop and ot-ctl ifconfig down commands to put thread in a disabled state?

    Hello Zhimin He,

    We do have a short section on power consumption on the op-ti GitHub repo which should help with reducing power consumption:

    Power Consumption Measurement

    Low power mode can be enabled/disabled by going to examples/apps/cli/cli_uart.cpp and changing the defines listed below.

    • TIOP_POWER_MEASUREMENT: disable UART/peripherals and automatically start thread device upon boot up.
    • TIOP_POWER_SED: will enable features to make device a sleepy end device (SED) and enter deep sleep mode.
    • TIOP_POWER_SSED: will enable features to make device a synchronous sleepy end device (SSED).

    The Thread network data/features can be modified by changing the defined value/variables listed below:

    • TIOP_POWER_PANID
    • TIOP_POWER_CH
    • TIOP_POWER_POLL_PERIOD
    • TIOP_POWER_CSL_PERIOD
    • networkKeyVal

    Thanks,
