mitshell / cc2531 Goto Github PK

Good morning,

I'm trying to use the CC2531 with a Beaglebone running Debian for the first time. Previously I used a Beaglebone running Angstrom with the CC2531 with success. Now I'm getting this error and all my efforts to solve it are in vane. Ant help would be very appreciate

my cc2531 dongle can only use in windows,my linux can't find the driver for cc2531.
i had try to update my kernel configure with ti serial,but i still can't use it in linux
could you give me a firmware of cc2531 used by this project

Hi, I'm trying to use your code on Raspi. I've changed gps.py to use /dev/ttyUSB0 -> /dev/ttyAMA0, but got the following error:

$ python ./sniffer.py -d 3 -p 5 -f
[sniffer] command line arguments:
Namespace(chans=[11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26], debug=3, file=True,
filesock=False, gps='/dev/ttyUSB0', ip='localhost', nofcschk=False, period=5.0, silent=False)
[interpreter] server listening on ['localhost', 2154]
[GPS_reader][ERR] cannot open /dev/ttyAMA0
[sniffer] no CC2531 dongles found`

when I do lsusb, it knows the device:

$ lsusb
Bus 001 Device 005: ID 0451:16ae Texas Instruments, Inc.
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter

however usb-devices says the following:

T: Bus=01 Lev=02 Prnt=02 Port=03 Cnt=02 Dev#= 5 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=32 #Cfgs= 1

C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)`

could the Driver=(none) part be a problem? What am I missing? Thanks!

When will this be updated to use pycrate, which is the replacement of libmich?

I already reflashed my CC2531 but I want to try your project. Is it possible to get default firmware to this device? Where can I download it?

Hello mitshell,

it's working better than the last week :)

I just tried your the code, and sometimes I've got this error:

[ERR] (Layer - <class 'libmich.formats.IEEE802154.TI_CC'>) String buffer not long enough for Correl

It may not be a bug, but I suspect a copy/paste issue between _get_ctrl() and _set_ctrl().

The method _set_ctrl() in CC2531.py, line 216 is calling libusb with l as the data argument. I do not know Python very well, so I am not sure how an integer gets converted into a byte array.

Would you have a pcap capture of the USB transfers when running the Windows application ?

Mitshell,

I'm using Ubuntu 14.10. x64. sniffer.py reports "[CC2531] cannot open USB device through libusb: add yourself in the "root" group or make an udev rule" even running under sudo. I then trace the error detail to libusb1 module and found it was LIBUSB_ERROR_TIMEOUT [-7].

When trying to initialize the sniffer, it exits with the following error:

[GPS_reader][ERR] cannot open /dev/ttyUSB0

This is using Python version 2.7.11, with both libusb and libmich at the latest git version.

Hi,
Kind regards. Getting this error when trying to run sniffer on raspberry pi.
pi@raspberrypi:~/CC2531-master/CC2531-master/CC2531 $ python ./sniffer.py --help
ERROR: cannot import python libusb1 wrapper.
