Problem in establishing communication between SORA and in-built wifi card in my laptop using SoraSDK 1.5 RRS feed

  • Question

  • Hi,

    I am trying to make communication between SORA and in-built wifi card in my laptop using SoraSDK 1.5.
    But not able to do so.

    Setup is as follows,

    1. Laptop

        192.168.1.11, 255.255.255.0

        "iwconfig" command gives output as:

        wlan0    IEEE 802.11bgn    ESSID:"sdr"
                      Mode:Ad-Hoc    Frequency:2.412 Ghz    Cell: EE:04:0B:C5:0D:4C
                      Tx-Power=15 dBm
                     Retry long limit:7    RTS thr:off    Fragment thr:off
                     Power Management:off

        Ran command 'iperf -c 192.168.1.22 -i 1 -t 100 -u'
        Also tried to ping to 192.168.1.22


    2. PC
        
        192.168.1.22, 255.255.255.0

        I have set BSSID in sdr.inf as "EE:04:0B:C5:0D:4C" and updated the driver.
        (Cell ID Looking at the output of "iwconfig" command in laptop)


        I have tried setting values as  

        dot11config -r 1000/5500/11000
        dot11config --rxpa 0x00
        dot11config --rxgain 0x1200/1400/1600

        iperf -s -u

        I can see in wireshark, the SORA card is broadcasting the ARP packets in the network.
        
        Wireshark  entry:                                                                                                                         02:50:f2:d8:d4:00 Broadcast ARP    42 Who has 192.168.1.254? Tell 192.168.1.22

        But I am not able to ping from 192.168.1.11 to 192.168.1.22.


    I am using Dell-Inspiron N-5110 laptop.

    Am I missing anything here ?
    Can anyone please help me on how do I go about testing the communication.
    how does the rxpa and rxgain values matter in experiments ?
    Should I just try all combinations of datarate, rxpa and rxgain or I can reduce the efforts ?

    I referred to the below link as well.

  • Hi Peeyush,

    Before you try TCP, you'd better try broadcast and UDP unicast on both directions first. The parameter (rxpa, rxgain, txgain) setting matters, Sora may not be able to decode packet from your in-built WiFi if the rx setting is not proper.

  • Can anyone guide me here ? Am I following the right steps ?

    I am afraid I am missing on some basics here.

    Can anyone  clarify on why do we use "dut" ? Is it just for testing the hardware before we actually start working on it ?
