Nvm Tool

Introduction

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

Example

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
