No WiFi?

geneb · 2016-07-01 16:10:14

I'm working on writing up the documentation for the DropLit v2 and I'm having a problem getting WiFi operating with nanoDLP. It works great over the wired connection, but doesn't seem interested in operating with the built-in WiFi of the Raspberry Pi 3 that is being used. Any suggestions?

I've also noticed that the auto-update notification only updates nanoDLP to Build 1165 and the release notes show the current release as 1183.

Thanks!

Latest stable version is 1165, beta version is 1183.

Do you see any error related to wifi on dashboard application log?

geneb · 2016-07-01 21:02:09

The application log is a never-ending litany of "Data Received wait".
I've never used a Pi 3 before, so I'm not sure what to go grepping for in the messages and syslog file. There IS a printer.log file that appears to contain dump data from a crash of some kind.
I can send that file your way if you want it.

As the program get killed on rpi shutdown, it could throw errors. But if there are error logs belong to the time which system should works normally, please share the log files.

You should see messages like this, on startup which could indicate any wifi related problems too.

	WIFI	WIFI interface wlan0 detected

geneb · 2016-07-01 21:37:16

I dug around and found various mentions of wlan0,
The first mention on boot is here:

Jul 1 18:19:21 raspberrypi systemd[1]: Starting ifup for wlan0...

There are previous entries from March 30th, but I suspect those were on the nanoDLP SD card image.

When I check the network interfaces via ifconfig, it shows wlan0, but it doesn't have an ip address associated with it. I'm not familiar with DHCP on *nix systems, so I don't know if that's the correct operation or not. It does appear to be obtaining an IPv6 address which is kind of wacky as I don't think my router is broadcasting anything other than IPv4 services. (Then again, it's Comcast, so those bastards could be doing /anything/.)

Here's the results from ifconfig:

Take a look at this page http://nanodlp.com:8080/
You should see toggle button at bottom left. Find the same button on your local rpi and click on it, it should display real-time log about wifi connectivity on startup or config changes.

geneb · 2016-07-03 00:20:08

The only thing I've EVER seen after hitting ""Toggle Log" is a never ending repeat of "Data Received wait".

Could you share debug file? You can exporting that by visiting setup page/tools tab/debug button

geneb · 2016-07-03 19:53:21

Here you go:

It looks like nanodlp receives tons of wait messages from RAMPS board. As it generates lots of data I could not see any wifi related message. Do you know why ramps send wait message? Have you tried any other firmware?

geneb · 2016-07-06 13:28:44

It's not a RAMPS board, it's a Mini-Rambo running Repetier Firmware. No chance of using a different firmware.

I don't know why it sends the wait message, but you might want to add a configuration option to supress it from the log. I suspect it's a feature of Repetier Firmware.

Disconnect RAMPS board see if you could get any useful log out of wifi module.

geneb · 2016-07-06 13:53:09

It's not a RAMPS board. I'll try running it disconnected when I've got time.

tnx.

I'm running build 1209 at the moment, and trying to connect to the Wifi at work. It's an enterprise system though, so I need to enter a username and password to authenticate, not just a WPA key. Is there a way to do this in the current build? If not, can it be added to the roadmap?

Shahin · 2016-10-05 06:24:42

Adding support requires testing environment, if you could setup wifi connection through bash (ssh), share command which you have used. I will try to add them to nanodlp too.
