Can't access wifi
-
Oh crap ... left the dashes in the config.g file .... it's been a rough day
will try again! -
Haha, the I shouldn't be a problem, but removing it would remove any doubt about qoutes, thats why I mentioned it.
what i should have typed:
m589 s"---------" P"-------------" i00.00.00.00
should be either
M587 S"---------" P"-------------";Connects to SSID --------
M552 S1
or
M589 S"---------" P"-------------" I"196.168.10.1";Creates SSID ----- and offers DHCP addresses in 192.168.10.0/24
M552 S2 -
Still no joy
-
Do you have a panelDue? if so create a macro and run that from the screen.
if not, create a trigger and attach it to an endstop and then have the wifi code in that?
edit: or usb and serial terminal is also good and interactive.
-
No I don't but just came up with another thought - I will need to give the M587 a letter salad in order to preserve the case of the letters.
Here goes nothing .... crossing fingers .... -

I was under the impression that was only needed for something like ponterface which translates all g-code to upper case? Still using ' to force them lowercase should work regardless of serial or config file methinks. I just seem to recall there is something preventing it from enabling the wifi module until after config.g is done. (maybe M552 S0 takes care of that idk)
-
Yes, I was under the same impression ....
and the rest of the config.g includes an M552S1and
No dice, that would have been too easy ....
-
Time to pack it in for the night. Maybe some other people will chime in overnight.
Thanks for your help! -
That ***** me off... so I tried on a board here.
Think the second G4 is redundant, but uncomment if it still doesn't work. Confirmed working from config.g even though its baaaaaad mojo.
M552 S-1 M552 S0 ; take AP out of reset, just in case G4 S1 M588 S"*"; forget all previous access point info ;G4 S1 M587 S"---" P"---" M552 S1 -
(Culprit was something in the lines of failed to bring wifi out of reset code -7 or something like that, which showed up on the serial port and paneldue.
oh, found the serial terminal still open, will add output in case people go searching.
WiFi module started M587: Failed to add SSID to remembered list Turn off the current WiFi mode before selecting a new one Error: Failed to initialise WiFi module, code -7Next time grab a usb cable:))
-
Thanks, I will give it a try tomorrow morning.
Interesting about adding dwell times - I would have never thought about that but it makes sense ! I will also try with and without M552 S-1 as I am thinking that S0 should be ok ... but don't know for sure.
If I do grab a usb cable and even plug it in on both ends, then what? Do I load a terminal program ? I am running Linux btw. Never tried that before. -

some wifi modules say failed to add network bad format or something like that; the S-1 is just a potential safeguard against that, it won't hurt at least.

yeah, screen, minicom or picocom should work.
do
dmesg | tailto see what /dev/tty* device the new serial port is called. Probably something like /dev/ttyUSB0 or /dev/ttyAMA0 depending on your distro and the angle of the moon. -
@jens55 what firmware version? There’s a bug in early RRF3 versions that doesn’t save the password. Use latest 3.01 RC4. M552 S-1 turns off Wifi, so you can’t add SSID, needs to be in idle mode S0. Though turning off, then idle mode, before sending SSID and password can help.

I am running RRF 3.01-RC3
When hooking up via USB I get something in the line of "no known network found" so I am assuming I have to go to RC4.
SInce I can't update through DWC, which files do I need to put onto the memory card directly to do the upgrade ?Edit: I copied Duet2CombinedFirmware.bin over to the memory card but there was no change.
Edit 2: serial port running M587 seems to report no networks found so maybe the upgrade to RC4 did not complete ?
-
@bearer , thanks for the instructions re connecting USB - worked great. Still not up and running but I am sure that's just the RC4 upgrade.
Thanks again for all your help! -
@jens55 it was fixed in 3.01 RC1, so it’s not that. Sounds like non-alphanumeric characters in SSID or password is the most likely issue, but have had a couple of problems with new router hardware. See this other thread: https://forum.duet3d.com/topic/14993/cannot-connect-duet-wifi-to-new-wifi-router/50
Also, check how serial comms are set up https://forum.duet3d.com/topic/12649/m587-ssid-contains-character/2?_=1584716082602
There was also a thread about Linux using non-standard codes for some characters, but I think it was the same thread as in the above paragraph.
Finally, if the SSID is hidden, you need to specify it when enabling networking, eg M552 S1 S"ssid"

While I normally like a challenge, this is getting hard on my forehead and the drywall from too much bashing my head against the wall.
I still can't see the device in my 'connected devices' list on either network
I have now changed the network to be visible.
There is a tiny bit of good news, the serial connection now gives me:
failed trying to connect to "-----" , wifi module is idleAs I said, I have one non alphanumeric character in the password, a period ..... ?????
Edit: the ssid it is trying to connect to is the correct ssid
-
@jens55 said in Can't access wifi:

As I said, I have one non alphanumeric character in the password, a period ..... ?????beyond "bug" that should leave only signal strength and encryption.
a period shouldn't pose a problem neither for RRF or your linux terminal but share the details of which terminal you went with and I can try it (also if the period is first, last or in the middle of the key just for good measure)
-
Plenty of signal and no interference. The network uses wpa2 personal, period is in the middle. I used puTTY as the terminal program. The terminal program is configured for 9600 8 1 but does show occasional odd characters but is of course only used as an additional source for diagnostic. It is however annoying that the duet spits out a more or less continuous stream of text which may or may not indicate that something is misconfigured. I can however enter commands in a fashion and get a proper terminal response (in amongst the text the duet is constantly streaming)
I have set things aside for now as sometimes I can't see the obvious when I get so wound up.
