Writing nvm file '/etc/6lbr/nvm.dat' Error writing nvm file: Permission denied

I checked the path and there is no nvm.dat file. And my nvm_tool file is also weird. Here you can see the file some parts of it nvm_tool.txt attached

laurentderu commented 8 years ago

/etc/6lbr/nvm.dat is usually owned by root so a normal user can not modify it. Either run nvm_tool as root or use another file, e.g. : 

/usr/lib/6lbr/bin/nvm_tool --update --channel 25 my_nvm.dat

Please provide more contextual information to your issues. I don't see anything wrong in your setup, so I guess the issue is on your PC, please check https://github.com/cetic/6lbr/wiki/6LBR-Connection to configure it properly.

MODE=ROUTER RAW_ETH=0 I changed the conf file as BRIDGE=1 CREATE_BRIDGE=0 DEV_ETH=eth0 DEV_BRIDGE=br0 DEV_TAP=tap0 RAW_ETH_FCS=0 DEV_RADIO=/dev/ttyACM0 BAUDRATE=115200 SCAN_DEVICE=/usr/lib/6lbr/bb-scan-usb.sh LOG_LEVEL=3

Now I am able to access to the web and connected to sensor but I receive errors in the log below;

laurentderu commented 8 years ago

A few ack-timeout or unknown command errors can happen at 6LBR start up as the slip-radio is maybe not properly synced. It happens more often with CC2530. If it happens again, it may be due to some other process trying to read from the slip-radio device.
