Original question:

RTOS/CC1352P: Role of Short Address in FH mode

CC1312R: FH mode short address

Part Number: CC1312R

Hi all,

Just start working on FH mode, found something is different from non-bean mode we used before. The question is will the collector (CoP/SensorToCloud) assign a set of new short addresses for the sensors every time the network restarts? my setup is one CoP/SensorToCloud, 10 sensors. The CoP will be on for 1hr, and off for one hour, during the off time, the radio is turned off. I noticed that, all sensors rejoin, but the short address are different each time. is this correct?

thanks,

-Yue

    Hello Yue,

    This looks like the collector is not saving all the connections. This is not the way it should work out of the box, verify that the NV_RESTORE option is set. This is a pre defined symbol.

    To further understand why this is happening, can you provide us with version of the SDK you are using and the devices being used also?

    Thanks in advance,

    AB

    Thank You, AB!

    We are using CC1312r for both sensor and CoProcessor, all running on simplelink_cc13x2_26x2_sdk_3_10_00_53,  TI 15.4 ti154stack_linux_x64_2_09_00_09, one thing i changed is that i turn off radio when 'off' with

    ApiMac_mlmeResetReq(TRUE).

    the coprocessor.opts has NV restore on

    -DNV_RESTORE

    My understanding is that every time I start he SensorToCloud, the collector will reinitialize the CoP with nv-simulation.bin, isn't it?

    ; Set to false to not reload the NV settings and start fresh each time
        load-nv-sim = true

    Hello Yue,

    You understand this correctly. Did you re compile the code with these settings and still doe snot work?

    We just released the newest SDK version 3.30, I recommend you update to this one.

    Regards,
