zhengyangtongxie commented 8 years ago

hello,I have followed your guide and successfully install gattlib. However,when i type it on terminate: sudo python ble-scan.py I received that:

Traceback (most recent call last): File "scan.py", line 4, in devices = service.discover(2) RuntimeError: Set scan parameters failed (are you root?)

My operate system is ubuntu 15.04 which work on vmware workstation, Do you know how to solve it ? Thank you.

Hello. Also I have the same problem. Do you have any solution. Thank you.

@aytekno hi,aytekno. The virtual machine can't work well.You must install gattlib on your original operate system.Hope it will help you.

You may have Bluetooth USB one more. you try command: hciconfig

In code you change line 20: service = BeaconService("hci0") // to hci1

it will help you. ^^

I get the same error on Raspberry 3, "hci0" should be correct. Still "RuntimeError: Set scan parameters failed (are you root?)". Any ideas?

pariwat commented 7 years ago

@PugSQL You should turn off any bluetooth devices and run python script. ^^

Hi, I found original library from BLE at pygattlib/discover.py that fixed this issue in my discovery.py. There you must import from gattlib not bluetooth.ble and import DiscoveryService

Thank you Tiana.

This worked for me. From https://unix.stackexchange.com/questions/96106/bluetooth-le-scan-as-non-root

sudo apt-get install libcap2-bin # was already installed
sudo setcap 'cap_net_raw,cap_net_admin+eip' `which python3` # problem: python3 was a symlink to python3.7
ls -l /usr/bin/python3 # where is the symlink going
sudo setcap 'cap_net_raw,cap_net_admin+eip' `which python3.7`
python3 scanBLE.py
