Compiler/CC2652RB: CC2652RB with TI15.4 few questions.

1. It's not recommended to send broadcast messages to sensor node since sensor node is under sleeping most time and it might miss broadcast messages.

>>>>>>i already disable sleepy node,so how can i send broadcast message?

You'll have to remove the following lines from sendBroadcastMsg():

    /* Current example is only implemented for FH mode */
    if(!fhEnabled)
    {
        return;
    }

Sorry to misleading on short address assignment in 15.4 Stack and Thanks Ryan to correct this.

HI Ryan,

thx for your reply.

On question 1, as YK pointed out broadcasts are best suited for Frequency Hopping mode.

>>>>>>>>In 2.4Ghz mode,Can the frequency hopping mode be enabled?

because collector.syscfg show Frequency hopping is not support on 2.4G band when i modify frequency mode.

Hi Weli,

Frequency Hopping mode is not allowed on the 2.4 GHz frequency band.  https://dev.ti.com/tirex/content/simplelink_cc13x2_26x2_sdk_4_20_00_35/docs/ti154stack/html/ti154stack/frequency-hopping-mode.html#introduction

HI Ryan,

thx for your replay,

so on the 2.4G band,we can't using broadcast function,right?

because broadcast function must based on frequency hopping mode.

I think you still can use broadcast but you have to comment out those lines in source code that I mentioned before.

HI YC,

I'm tried to comment fhEnabled in sendBroadcastMesg function.

and i call generateBroadcastCmd(); function in collector,

but sensor node never received broadcastCmd.

If you setup sniffer, can you see broadcast message is sent over the air?

Hi Weli,

Please specify how you disabled sleep mode on the sensor node and verify that the sensor does stays in active mode.  As YK mentioned it would help to provide a sniffer log of the broadcast message, also debug ApiMac_mspsDataReq of sendBroadcastMsg to verify that it returns successfully.

Regards,
Ryan
