serial.serialutil.SerialException: Attempting to use a port that is not open #7

Trying to use sniffer.py on macOS Sierra (10.12.1) is giving errors:

ble-sniffer-osx from Roland King works, so it is not an OS issue nor a hardware issue.

It also looks like there have been others who ran into this issue. See the following thread: https://forums.adafruit.com/viewtopic.php?f=22&t=82839&sid=643613138ca6829f5444dd61c1cabc7d&start=15 (Workaround mentioned there, to install 2.3 FTDI driver, does also not work).

ckuethe commented 7 years ago

I've seen this a few times on Linux 4.8.8 today; I'm guessing it's a hardware problem related to my USB hub.

mandersen commented 7 years ago

Still seeing this with macOS 10.12.3 (16D32). ble-sniffer-osx works, but not sniffer.py. Fails with same error as above.

vshymanskyy commented 7 years ago

I think I had the same problem on Linux, and I have finally fixed it. I'm still working on it, and will publish a fix on my fork soon: https://github.com/vshymanskyy/BLESniffer_Python

vshymanskyy commented 7 years ago

Ok, seems to be fixed on my fork: https://github.com/vshymanskyy/BLESniffer_Python

itemir commented 7 years ago

Thanks for the fix. Unfortunately I cannot test it as I sent the unit back.

dsweetkulshantechnology commented 7 years ago

I was running into the same issue on macOS today and came across this bug.

Tried @vshymanskyy 's latest fork and crash no longer happens. However, it appears it is not detecting any devices in the scan and sits in a Scanning for BLE devices (5s) ... loop forever. I know there are devices advertising and my HW is functional since the same setup is receiving packets on the PC version+wireshark.

It also appears my log file is filling up with "SLIP skipped" exceptions, which appears to be a new addition.

vshymanskyy commented 7 years ago

@dsweetkulshantechnology "SLIP skipped" was added to diagnose Serial stream errors. I cannot test on OSX currently. What is syour version of OSX and hardware? Thx. Could you also check my for on a PC? it also supports live capturing with --pipe flag

vshymanskyy commented 7 years ago

Also, my version should show FW version: 1111. if it shows version 0, it means it just can't get in sync with serial stream. You can try this:

  1. unplug the board
  2. plug it in
  3. wait 10 secs
  4. run the sniffer script
vshymanskyy commented 7 years ago

@dsweetkulshantechnology please try my latest master branch - it works with my OSX

dsweetkulshantechnology commented 7 years ago

@vshymanskyy OSX Version 10.11.6 (El Capitan) on MBP, using the AdaFruit BlueFruit sniffer.

With latest version I can't seem to get anything except Firmware Version: 0 - tried replugging multiple times with varying delays.

Same result on Win7 PC (Firmware Version: 0).

On the PC with the Nordic SW (same HW dongle) I get the following (Version 12?!): image

jmartin-usna commented 7 years ago

I am running Ubuntu 16.04, using the Adafruit Bluefruit LE sniffer.

I have the same issues, unable to connect to the board:

Capturing data to logs/capture.pcap Connecting to sniffer on /dev/ttyUSB0 Software Version: 1111 Firmware Version: 0 Sniffer board is not responding. Please re-plug the board.

vshymanskyy commented 7 years ago

@jmartin-usna , @dsweetkulshantechnology - I think it would be best if I can perform some live debugging session with one of you guys.

nad0m commented 7 years ago

I am having the same exact issue. I've tried on all three platforms: Mac OS, Windows, and Linux.

hindfelt commented 7 years ago

Hi,

I get the same problem unfortunately.

alexeicolin commented 7 years ago

On my Arch Linux box and Adafruit BLE Sniffer (the CP210x one), this error reported above: "Sniffer board is not responding. Please re-plug the board." happens only for @vshymanskyy fork, not in this repo. With this repo, sniffer produces the pcap file fine.

I solved this by editing line 246 in SnifferAPI/Packet.py

Thanks @gnyman, that solved the issue on my mac.

The problem is now that it does not find any devices:

ladyada commented 7 years ago

uninstall the macos driver and re-install v4 - silabs released a broken driver

http://community.silabs.com/t5/Interface-Knowledge-Base/Legacy-OS-Software-and-Driver-Packages/ta-p/182585

you will need to uninstall the old driver using the script included ^ some people had to uninstall twice before re-installing

dbenninger commented 7 years ago

Uninstalled the driver, restarted my mac and installed the sw from the link above. Still the same issue...

sonelu commented 7 years ago

This is clearly a problem with the Python code.

If I run the sniffer like this:

python sniffer.py /dev/blabla

the result is:

there is no message that the port does not exist and was not able to open.

Reinstalling the driver had no effect. I'm on High Sierra 10.13.1, i've updated pyserial to 3.4, and running python 2.7.13 under Anaconda.

Is anyone really looking at this issue? Practically I got a £30 blue blinking led powered by my USB port...

1am commented 6 years ago

I'm experiencing the same issue on OSX and Ubuntu. The device worked some time ago when I've tested it on Windows which I no longer have it at hand. Is there a chance for a fix for this?

hornej commented 6 years ago

Anyone have any luck on this? I am still getting the same error on OSX

stefandz commented 6 years ago

I tried uninstalling the newer driver (twice, as suggested) and then reinstalling. Checking by hand I can see that only the older version of the Silabs kext exists on my system and still I get the same sort of issues that most people are seeing. Until there is a fix, my workaround is to use ble-sniffer-osx by Roland King which will capture into Wireshark 2.0.x (I had to remove my newer version). It's cludgy but it works.

canDry commented 6 years ago

I was getting USB issues (same SerialException error)... if I run this little bash script it resets the USB and things work again:

#!/bin/bash

if [[ $EUID != 0 ]] ; then
  echo This must be run as root!
  exit 1
fi

for xhci in /sys/bus/pci/drivers/?hci_hcd ; do

  if ! cd $xhci ; then
    echo Weird error. Failed to change directory to $xhci
    exit 1
  fi

  echo Resetting devices from $xhci...

  for i in ????:??:??.? ; do
    echo -n "$i" > unbind
    echo -n "$i" > bind
  done
done
airdrummingfool commented 6 years ago

I was experiencing this same issue. Doing the following fixed it for me:

  1. Remove the 5.x SiLabs VCP driver (5.0.5 in my case), restart, and install the 4.x driver version instead. The older driver version is included in the 5.x driver disk image under the "Legacy MacVCP Driver" directory. I then used kextstat | grep silabs to make sure that the 4.x driver was installed instead of 5.x.
  2. Apply the fixes from PR #16.
