cc1310: Regarding the 6lowpan application

Part Number: CC1310
Other Parts Discussed in Thread: CC1310, CC2650

Hello,

I am using the chip set CC1310F128RSMR to development 6lowpan application.I am using latest contiki from github . In firmware development I am using examples in the example/ipv6/simple-udp-rpl is modifying according to the requirement.
Here I am facing these problems.
1) when the master sends broadcast packet the available slaves are responded to that broadcast message ,Here in that instant I am unable to get the all available slaves in single time,but while I have observed in the sniffer  its shows all nodes are responded i.e,in the RF layer is present but my master node is unable to receive it.
I have apply these settings in my Master node --- RDC ==   contikimac_driver  MAC == csma_driver , NETSTACK_MAC.off(1)  In smart-rf settings we are using GFSk and 50kbps channel .

Here I have tried all the combination of RDC &MAC but I am  unsuccessful and above is the best combination to get 50% throughput.

2) I would like to know is their any feedback for RF sending ,although I am UDP protocol so it does not have ACK but I have observed that ACK packet is coming. what setting  have to done for disable.
3)The maximum payload in the UDP packet that should not involves in the internal fragmentation.

    Ganesh,

    On the collector side and maybe the sensor side also, modify the contiki-conf.h file to remove the power save features of the cc1310 device. This speeds up the response time.

    /*
    * If set, the systems keeps the HF crystal oscillator on even when the radio is off.
    * You need to set this to 1 to use TSCH with its default 2.2ms or larger guard time.
    */
    #ifndef CC2650_FAST_RADIO_STARTUP
    #define CC2650_FAST_RADIO_STARTUP 1 // default is = 0, I suggest changing it to 1
    #endif
