Hello,

I'm trying to run you sample code (http://ianharvey.github.io/bluepy-doc/scanner.html#sample-code) on my orangepi with a bluetoot v4 dongle, but it doesn"t work.

root@orangepipcplus:~# python test.py Traceback (most recent call last): File "test.py", line 14, in devices = scanner.scan(10.0) File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 679, in scan self.start(passive=passive) File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 617, in start self._mgmtCmd("le on") File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 276, in _mgmtCmd "Failed to execute mgmt cmd '%s'" % (cmd)) bluepy.btle.BTLEException: Failed to execute mgmt cmd 'le on'

Any idea of what's wrong ?

PrzemoF commented 6 years ago

Did you try with sudo?

edouardkleinhans commented 6 years ago

all the command are executed as root.

goldfingyr commented 6 years ago

I think I have the same problem just with the TI Sensortag (running as root - debugging on). Running on a Raspberry Pi with a BLE USB; hcitool is able to scan:

sudo python sensortagcollector.py Running /usr/local/lib/python2.7/dist-packages/bluepy/bluepy-helper Sent: le on

Same issue for me. On a Orange PI Zero , i've try 2 different USB adapter ( CSR 4.0 and Orico ) Both working perfectly with hcitools.

What output does bluepy-helper give when you run it directly? /usr/local/lib/python2.7/dist-packages/bluepy/bluepy-helper 0 help le on

rosshadden commented 6 years ago

I had the same error, but sudo makes it work for me. Do we know which group or permissions it requires? I would like to make it run with my user.

SHA89 commented 6 years ago

sudo setcap 'cap_net_raw,cap_net_admin+eip' bluepy-helper This gives everyone permission to execute bluepy-helper.

i tried all the answer i could find, tried running as root, with sudo, i checked the interface and it's 0 def init(self, iface=0):

anyone can help?

SHA89 commented 6 years ago

have you tried running bluepy-helper directly and tried to execute "le on" manually?

hasamba commented 6 years ago

im getting: "bluepy-helper: command not found" eventough i can see the file and it is executeable

SHA89 commented 6 years ago

I guess you are not so familiar with linux command line. to run the executable, you must execute it the following way: ./bluepy-helper 0 If you forget the "./", the system will assume you try to start a program that is available in your PATH. With the "./" you give the direct address of your executable. The "0" defines the interface you want to use. If you only have one bluetooth interface, 0 will be correct, if you have multiple, you can use 1, ...

If the program complains about permissions, try it again with super user rights: sudo ./bluepy-helper 0

hasamba commented 6 years ago

thanks for your explanation, i learned something new :) im running now /usr/local/lib/python3.5/dist-packages/bluepy $ ./bluepy-helper 0 help le on and im not getting any response, just the curser blinking, is that ok?

same with sudo

SHA89 commented 6 years ago

if you type 'help' you will see all possibilities. As i can see in your error message, your problem already occurs when trying to execute the command le on (to put it in bluetooth low energy mode) so i suggest you try that command.

hasamba commented 6 years ago

for some reason "help" also doesnt give me any result...just blinking

SHA89 commented 6 years ago

i'm using it in python 2.7 but i'll set up a 3.5 to test

It seems to work on my computer. I also have a blinking cursor, but if i type help, i do get this help message. And have you tried other commands? Do you see "help" appearing on your blinking cursor as you type? don't forget to press enter.

SHA89 commented 6 years ago

Just to be sure, you have to start the program with sudo ./bluepy-helper 0 and after it's started, you need to type 'help' or 'le on'

flatsiedatsie commented 6 years ago

Same error, but when doing multiple calls in quick succession. Python 3.4 on a Pi Zero W with Dietpi Stretch.

shumingli708 commented 6 years ago

I typed 'le on' on bluepy-helper, and I got 'rsp=$mgmt code=$protoerr'.

hasamba commented 6 years ago

now im able to run and getting same message: rsp=$mgmt code=$protoerr

SHA89 commented 6 years ago

i also get the protoerr if i'm not running as superuser (sudo ./bluepy-helper 0).

So first you need to check if you have the problem as sudo-user sudo ./bluepy-helper 0 le on
If it works with sudo, and you want to be able to run it as a normal user, you need to set capabilities on the executable. try: sudo setcap 'cap_net_raw,cap_net_admin+eip' bluepy-helper (make sure u are in the directory with the bluepy-helper executable) I don't know exactly what this does, but it allows me to run bluepy-helper without root privileges (sudo)
Now you can run it as a normal user with ./bluepy-helper 0

If you have problems, please post the commands you used and the output. FIY i'm running it on ubuntu 16.04 and tested it with python 3.5

hasamba commented 6 years ago

i ran it before with sudo.

sudo ./bluepy-helper 0 le on rsp=$mgmt code=$protoerr

im on mint (ubuntu 16.04), python 3.5.2

SHA89 commented 6 years ago

In that case i don't have an explanation, my solution was the capabilities.. Maybe have a try with gatttool to see if you can set up a connection, and hciconfig to check if your bluetooth interfaces are up and running

hasamba commented 6 years ago

thanks again for all your help

flatsiedatsie commented 6 years ago

Here the issue still persists if there are multiple calls in a row:

on Domoticz plugins are run an root, so that's not an issue.

PrzemoF commented 6 years ago

I'm still testing, but this works [EDITED]:

Start from one terminal: sudo /usr/local/lib/python3.6/site-packages/bluepy/bluepy-helper 0 or wherever you have bluepy-helper
Type "le on" and you should get this: rsp=$mgmt code=$success
Do whatever you need to do from another terminal.

Tasm-Devil commented 5 years ago

Hi. The Error still exists. With sudo it works:

me@mypc:~$ sudo ./.local/lib/python3.6/site-packages/bluepy/bluepy-helper 0

\# bluepy-helper.c version 1.3.0 built at 20:40:35 on May  3 2019
le on
rsp=$mgmtcode=$success

But without sudo it wont:

me@mypc:~$ sudo setcap 'cap_net_raw,cap_net_admin+eip' ./.local/lib/python3.6/site-packages/bluepy/bluepy-helper

me@mypc:~$ ./.local/lib/python3.6/site-packages/bluepy/bluepy-helper 0

\# bluepy-helper.c version 1.3.0 built at 20:40:35 on May  3 2019
le on
rsp=$mgmtcode=$mgmterrestat=h14emsg='Permission Denied

Are there any plans to fix it. I want to use bt-mqtt-gateway to get a connection to an nrf52840 running circuitpython.

doronator commented 5 years ago

Note that when running python scripts with sudo, your normal user and the super-user ivoked by sudo, may have a different default python location.

When using sudo with running a python script you may need to specify the full system path to the version of python you inteend to run

Re: https://github.com/IanHarvey/bluepy/issues/218#issuecomment-350680433

sudo setcap 'cap_net_raw,cap_net_admin+eip' bluepy-helper This gives everyone permission to execute bluepy-helper.

cap_net_admin,cap_net_raw+ep without i ("inheritable") is sufficient:

$ sudo setcap cap_net_raw,cap_net_admin+ep bluepy-helper
$ getcap bluepy-helper
bluepy-helper = cap_net_admin,cap_net_raw+ep
$ bluepy-helper
# bluepy-helper.c version 1.3.0 built at 06:27:58 on Jul 16 2019

Firstly, make sure that your BLE device is existing, using following command

$ hciconfig

If the device is existing, it will like this

hci0: Type: Primary Bus: USB BD Address: 00:1A:7D:DA:71:11 ACL MTU: 310:10 SCO MTU: 64:8 UP RUNNING RX bytes:883983 acl:0 sco:0 events:23598 errors:0 TX bytes:6053 acl:0 sco:0 commands:160 errors:0

Your error is because that the BLE device is not activated. You can use this command to activate it.

$ sudo hciconfig [hci0] up

santobedi commented 2 years ago

Hello @EricRongkai,

$ hciconfig gave me

Command 'hciconfig' not found, but can be installed with:

sudo snap install bluez  # version 5.48-3, or
sudo apt  install bluez  # version 5.53-0ubuntu3.3

I installedsudo apt install bluez # version 5.53-0ubuntu3.3 and ran $ sudo hciconfig [hci0] up, however, I get Can't get device info: No such device. Same thing happened with sudo snap install bluez # version 5.48-3.

Now, when I run hciconfig, nothing happens. I still get rsp=$mgmtcode=$mgmterrestat=h11emsg='Invalid Index after le on command.
