CCS/CC1310: Power Consumption in Joining & Orphan State

Dulip Madurasinghe
Expert 1235 points
Part Number: CC1310

Tool/software: Code Composer Studio

In the sensor collector example. The power consumption for the following states are as follows,

Joining State - 7.04mA /TX - 15.5mA

Joined state - 0.4mA/TX - 6mA

Orphan state - 7.04mA/TX - 16mA

* TX - Transmission in the respective state.

The reason for this much of power consumption is due to RF RX or any other reason? How can I reduce this?

This is a very critical problem for me. A response highly appreciate.

    Hey Dulip,

    Can you try increasing CONFIG_SCAN_BACKOFF and CONFIG_ORPHAN_BACKOFF? These values are the amount of time in milliseconds the device will sleep between scans. If you are still seeing unusually high consumption I can test using a power analyzer.

    Hi Brocklobsta ,

    First of all, I used FH mode for above experiment.
    I tried your suggestion. The following changes were done.


    #define CONFIG_SCAN_BACKOFF_INTERVAL 50000 //5000

    #define CONFIG_ORPHAN_BACKOFF_INTERVAL 3000000 // 300000


    But the result was same as before. It continues the same power consumption pattern. Can you please look into this matter?

    Thank you very much. kindest regards.
