Sensor Export default disable

[steven3w]

Hi 6lbr team, I notice the V1.4.1 has Export added at Sensors tab on the 6lbr web page. I have tested it and found the default is disable. How to make it default enable. And is there way I can limit the record number?

This feature is still experimental and to be documented :)

You configure it using the /etc/6lbr/nvm.conf file with the following entry :

[node-info.export]
enabled = 0 | 1 #Enable or disable the functionality at BR startup
global= 0 | 1 #Dump date in one global file or a file per node
filename=... #Name of the dump file if global file is used
path=... #Path of the dump subdirectory 
interval=   #Interval between dumps in seconds

Currently there is no limit, but indeed this could be added. What kind of limit would you suggest, time ? number of records ?

hi, Laurentderu,

Thank you. I check my beagle bone black, there is no /etc/6lbr/nvm.conf file there. Do you mean I can create a new file with the option contents?

As for the limit, number limit is better, I think, because if I access it from a application program I want read it as fast as possible and I only care the last couple of records.

Hi, Laurentdeu,

I suggest export should include RSSI. It is useful to express a link's quality.

enabled = 0 | 1 #Enable or disable the functionality at BR startup

It should be enable=1, i believe.
