Using windows 10 OS, and SES v5.40.
I am using nRF52833 device in my project along with nRF5_SDK_for_Thread_and Zigbee_v4.1.0_32ce5f8 SDK.
I am using openthread protocol for radio communication and i also know that we can use the below function to know the radio state and also joiner state
otJoinerGetState(ot_instance) - Joiner state and otPlatRadioGetState(ot_instance) - Radio state.
But if i try to print the radio state : Observations
a. Before joining - the radio state is 1(radio sleep) - power consumption is around 15uA - expected to be that power consumption.
b. During joining - the radio state toggles between 1,2,3 (sleep, Rx and Tx) - power consumption is around 20mA - Expected this power consumption during pairing.
c. After joining - the radio state is 2(Rx) once pairing is completed, and it doesnt goes to sleep anymore - power consumption is around 11mA - Expected to be 15uA once the device is in sleep.
Questions :
1. I tried to put the radio to sleep manually once pairing is completed - Facing issues with communicating again once pairing is done. Also found that there is no requirement of manually switching sleep and receive states from this discussion - https://github.com/openthread/openthread/issues/1495 - Please suggest right way to handle this.
2. Also found the link mode configuration settings - otLinkModeConfig mode;
memset(&mode, 0, sizeof(mode));
mode.mRxOnWhenIdle = false;
We are making mode.mRxOnWhenIdle true during initialisation and again false during cyclic wakeup - is there anything wrong with this configuration setting.
Note : All i want to do is putting back the radio state to 1 (sleep) once it completes communication to reduce power to 15uA.
