Nvm Tool - cetic/6lbr GitHub Wiki

The nvm_tool is a command line editor for the 6LBR configuration. It can be used to create or update a NVM configuration to be flashed on an Econotag based 6LBR or to update the configuration file of a Linux based 6LBR

Usage: tools/nvm_tool COMMAND [OPTIONS]...  []

COMMANDS :
	--help				 This help
	--new [OPTIONS]... 	 Create a new NVM file
	--print 		 Dump the content of the given NVM file
	--update [OPTIONS]...  []
					 Update the given NVM file, the source file is reused if no destination file is given

Note that depending of the 6LBR mode used some parameters are not used

Create a new configuration with the rf channel set to 24 and the RA emission disabled :

 nvm_tool --new --channel 24 --ra-daemon-en 0 nvm.dat 

Display the content of an existing NVM configuration :

nvm_tool --print nvm.dat
