Tool/software: TI-RTOS
Good afternoon,
Now I measure current consumption based by sample code of power_management. I change the originally source code of use case Options 5 (for Always Connected) not to connect socket in order to only measure consumption of AP connection.In my assumption, this change and run means "MCU LPDS + NWP idle connected". However, the result of "MCU LPDS + NWP idle connected" is higher(1~3mA) than the data sheet (710µA) shown in below figure.
I don't understand the reason. Cloud you tell me what should I check and consider?
Result figure (IMETER):
Environment:
- Device: LAUNCHCC3220MODASF
- SDK: 2.10.00
- Mesurement Tool: IMETER-BOOST
- Probe supply Power: 3.6 V
changing point of source code(power_measure.c)
case UseCase_AlwaysConnected : prepareDataFrame(PowerMeasure_appData.port,PowerMeasure_appData.ipAddr); /* Start use case */ sleep(1); Power_enablePolicy(); sleep(LPDS_IDLE_TIME/1000); // measurement timing Power_disablePolicy(); UART_PRINT("Send Packet...\n\r"); //alwaysConnected(); break;
Just for reference
- I check DTMI period of AP, but it's same as data sheet (1).
- use case Options 2 result (for LPDS) is about 160µA. I assume this case is "MCU LPDS + NWP LPDS".
