Error: E_FETCH_SIGNAL_HW_TIMEOUT _ RRS feed

  • Question

  • Hello,

    I am running simple rx/tx experiment with iperf. However, I am having trouble with the error called E_FETCH_SIGNAL_HW_TIMEOUT. The error message are shown below.

    We installed SDRmini port driver to Windows XP. SDK version 1.6 and the board have WBX radio front end plugged in. Our desktop PC is shuttle PC model SZ77R5.

    Sender's IP 192.168.0.100 and receiver's IP 192.168.0.200.

    Sender's side is running: iperf -c 192.168.0.255 -i 1 -t 1000000 -l 1000 -u -b 10m

    Receiver's side is running:  iperf -s -i 1 -u and rxgain was set using dot11config.exe --rxgain 0x3a00 

    This error will not appear immediately. In general, this problem will show up after we run such experiment about 20 minutes or even longer. Also, both sender and receiver could have chance to get this error. 

    Uninstall and re-install driver cannot solve this problem. The only solution we currently have is to turn off the machine and turn on again after few minutes. 

    Can anyone tell us where to troubleshoot for this type of problem.

    Thanks in advance

    Muye Liu

  • Hi Muye,
    The error code E_FETCH_SIGNAL_HW_TIMEOUT means that receiving a complete signal block is time out. Normally it indicates something goes wrong with hardware reception.
    1. You can try: disable the drivers, reset the RCB board, reset the radio board, enable the driver
    2. We recommend you use latest Sora SDK 2.0. You can conduct the same iperf experiment with HWTest.sys driver and user mode 802.11a/b sample 'umxsdrbrick.exe' or 'umxsdra.exe'. They are better supported and improved compared with the previous implementation.
    3. You can diagnose the sora to sora environemnt with 'umxdot11.exe', which is straight forward frame generator and monitor. It is easier to tune than a full-fledged MAC/PHY program.

    Thanks, -Qi

  • Hi Muye,

    You need to upgrade your RAB firmware to support WBX radio.

    You may need to contact V3 again to ensure that the proper firmware. Sora SDK version may not be an issue.

    Thanks,

  • Hello Qi:

    Thanks for your suggestions.

    We will try the hardware reset you mentioned. 

    We have WBX radio front end plugged into the RCB board. Seems like this radio front end only works with SDK version 1.6.

    We contacted the V3 because we had "Error: no radio discovered" when we install SDK 2.0 to a Windows 7 desktop. The V3 tech support told us to use SDK 1.6 and Windows XP may solve the problem.

    However, we tried SDK 2.0 with Windows XP last week. It still produced error message "Error: no radio discovered". So, We think only SDK 1.6 works with WBX radio front end.

    Thanks

  • The V3 tech support gave us a copy of firmware last month (Sep/13/2013). We have uploaded that firmware to the RAB, it still gave us the same error message "Error: no radio discovered". We had to contact V3 again because we got the same error. 

    V3 tech support told us they ran test before they shipped out these boards. At that moment, their testing machines have Windows XP and SDK 1.6 installed. That is why we downgraded OS from Windows 7 to Windows XP and installed SDK 1.6

    Thanks
