Can't access wifi
-
I screwed my wifi setup today. I was trying to move the Duet to a different network and somehow managed to f$^% things up
At this point, neither the old IP network nor the new network registers the duet as connected based on the "connected devices" lists on either.
No problem said I (HAH, jinxed it right there!), did a bit of digging and added the following lines to my config.g (memory card removed from duet and inserted in computer)
m552 s0 ; take AP out of reset, just in case
m588 s"*"; forget all previous access point info
m589 s"---------" P"-------------" i00.00.00.00 ; set new access point with no network address definedI have replaced the actual ssid and password with dashes here.
The only thing I am iffy on is specifying the ip address in the very last line - the system is supposed to get the ip number from the network DHCP server.Well of course nothing happens and the printer doesn't seem to connect to anything and I can't get to the web interface because it's not connected.
Based on the lights on the duet, all seems well. The wifi module blinks once.A hint on how to proceed would be appreciated !

that should probably be
M587or have an actual IP defined with something likeI"192.168.10.1"but not sure how well it works from config.gand if you do want M589 and the duet to be an accesspoint you'll need a
M552 S2instead ofM552 S1after it. -
It might be - I haven't managed to figure out the subtle differences (if any) between M587 and M589. Both warn me not to use them in config.g
I will give M587 a try.
I used I00.00.00.00 (note, no quotation marks) based on what the duet returned to M587 or 589 when it was still working.

M587 is to connect to an AP, M589 is to provide an AP for you computer to connect to.
(note, no quotation marks)
not mandatory until RRF3 i think, so I just add them for good measure.
-
Ah, interesting, didn't know that the duet wifi could provide it's own access point. Cool
Thanks, I will try M587
Hmmm, there are no quotation marks in the gcode reference and I am running RRF3 ... I will add the quotation marks.

I could well be wrong on that account, but here is somewhere qoutes are required for RRF3 and not RRF2 at least.
edit: And for M587 you don't need to use I"0.0.0.0" to get a DHCP lease, only to override a previous static IP, as you used M588 S"*" that should render that a moot point.
-
No dice with switching to M587
I will try and remove the "i" bit -
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.

(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.
