Tutorial - running Duet Wifi 2 in Access Point Mode ?

Phaedrux

So with access point mode the printer doesn't connect to your phones hotspot. Rather the Duet creates a wireless network that your phone then connects to.

To configure access point mode you use M589

https://duet3d.dozuki.com/Wiki/Gcode#Section_M589_Configure_access_point_parameters

M589: Configure access point parameters
Parameters:

S"ccc" The SSID that the WiFi interface should use when it is commanded to run as an access point
P"ccc" The WiFi password
Inn.nn.nn.nn The IP address to use
Cnn The WiFi channel to use (optional)
Note: WPA2 security will be used by default.

And use M552 S2 to enable it.

Snnn 0 = disable networking, 1 = enable networking as a client, 2 = enable networking as an access point , -1 = disable WiFi module

On the Duet 2 WiFi running firmware 1.19 and later, the IP address is set in the M587 command when you configure the access point details.

@sputnikoc3d Hi,

I'm not sure I understand the point you are making.

All WiFi clients need to specify the SSID and password of the Access Point they want to connect to.

A device functioning as a "hot spot" is simply an Access Point by another name.

Or have I overlooked something?

Thank you ...

I am hoping to use this mode as a fallback option ... Id prefer to have the damn duet board function as expected and be able to connect to the PHONE's hotspot ... I will refer back to this as well if I give up on the phones hotspot connectivity being a bust...

My point is - ive done all that - but it appears [ as Ive tested looking for the duet on on the OLD network ... that regardless of my network params in config.g - it is looking for the old network vs. the new .... so one must TRY [ as its not working either ] to flush the boards memory of the old networks via the M558

Seems there was a typo in a thread on this subject where another person suggested using M588 "*" <---- asteric = SSID ... But ... it needs to be

M588 S"YourOldSSID" meh ....

for the benefit of future readers

M588: Forget WiFi host network
Parameters:

S"ccc" Network SSID to remove from the remembered list
The specified SSID will be removed from the remembered list and the associated password cleared out of EEPROM. If the SSID is given as "*" then all remembered networks will be forgotten.

M589: Configure access point parameters
Parameters:

S"ccc" The SSID that the WiFi interface should use when it is commanded to run as an access point
P"ccc" The WiFi password
Inn.nn.nn.nn The IP address to use
Cnn The WiFi channel to use (optional)
Note: WPA2 security will be used by default.

because I currently have wifi and router issues via my normal provider; Im trying to connect to my Duet via alternative means.

Preferred to use phone as hotspot - NUC is already connected - use Intel NUC to slice and send files to Duet - still use internet.
As fallback method - since #1 above is NOT working - setup Duet in Access Point Mode and connect the Intel NUC to it temporarily to send files and execute print.

Cant seem to get either option to function as desired atm ...

I am currently putting my SD Card into a USB stick and editing the config.g file - then restarting the Duet / printer. All my methods so far seem to be flawed not sure wth is going wrong

Phaedrux

Sorry, I misunderstood your first post.

I just tested using M588 "*" to remove all networks and it seems to have worked. How did you send the command? I used the PanelDue console.

I also tested joining a hotspot on my iphone 6s and it connected.

This was on firmware 2.02 and wifi server 1.22.6. What versions are you running?

SputnikOC3d

Seems as if the Duet is STILL ignoring my M588 S"SSID" command on reboots and conecting to the nonfunctioning router - it can act as a router - but has no access to Internet and the ISPs DNS - and therefore no functional routing essentially.

Im finding the Duet on the OLD network still by using the FindMyDuet android app on my phone and connect the phone to the old network

SputnikOC3d

I do not have paneldue [ biggest mistake of my entire 3d printer career obviously ] [ that or not choosing wifi over ether net wired connectivity ] - ive tried sending via the config.g in startup boot

For clarifications ...

Can I even do this via the config.g [ issue M588 ] ?

Additionally - can I use M588 "*" - literally - exact text ? as the doczuki gcode references are M588 S"YourSSIDsHere"

Ive unplugged the old wifi router that Duet insists on connecting to. Now - the Blue LED that normally illuminates on my Duet for the wifi connection is DARK ... and I cannot find the baord anywhere - it isnt trying to connect to my phone either ... all the other devices in the house are - from 300 feet away too ..

above is the latest iteration of the network section of my config.g .... now the led for the wifi module just flashes once and then does nothing - goes dark . . . its not trying to do anything

Can you connect via USB so you can send commands via the console and get back responses?

What if you break up the commands between boots. So the first power on you have M588 "" in config.g. Wait for it to finish booting, then power down, remove M558 "" from config.g and boot up again.

Ok well nothing on the connecting to the phone worked [ andoid galaxy S9 ] ... so now I shall try my hand at the access point mode - not very optomistic ...

Q1 - i can select just any IP address off the private networks aka 192.168.1.xxx ?

Q2 - Does the M552 S2 gcode in config .g come before or after the M589 et al ... ?

this speaks to my point above prior about 97% documented info - leaving out niggling little details that waste users hours of time sorting ...

Its possible yes ... Id have to download YAT or Pronterface again over 2G wireless - AND - relocate the printer for the lentght of the USB with the small conector on it for the duet board - to reach. Giant PITA ...

@sputnikoc3d The ip you choose for the Duet to use is irrelevant since it acts as the router in this case and is creating the network, so it has no way to conflict with any other network. And since you'll be joining the network by SSID you don't even need to know what the IP is to connect to it.

I had M589 before M552 S2, but I'm not sure if it matters.

Perfect ... thank you ....

Also in regards to the GCODE Doczuki and some of the commands / syntax as posted - its weird to me that some parameter require " " quotes and other - apparently like I for IP ... Do Not

M589 S"DuetWiFi" P"BlahBlahBlah" I192.168.1.101

or ... ????

M589 S"DuetWiFi" P"BlahBlahBlah" I"192.168.1.101"

the differences leads a novice like myself second guessing - and if this didnt work would have me redoing my config.g to try either or - vs. it being common / same - throughout ... and specified and noted - and where it differs like it does in the docs to be noted and marked as such ....

Phaedrux

Yes, sending natural language to machines is always a little problematic.

https://duet3d.dozuki.com/Wiki/Gcode#Section_Quoted_strings

Quoted strings
In RepRapFirmware, quoted strings are permitted anywhere a string parameter is expected. This allows file names, WiFi passwords etc. to contain spaces, semicolons and other characters that would otherwise not be permitted. Double-quote characters are used to delimit the string, and any double-quote character within the string must be repeated.

Unfortunately, many gcode sender programs convert all characters to uppercase and don't provide any means to disable this feature. Therefore, within a quoted-string, the single-quote character is used as a flag to force the following character to lowercase. If you want to include a single quote character in the string, use two single quote characters to represent one single quote character.

Example: to add SSID MYROUTER with password ABCxyz;" 123 to the WiFi network list, use command:

M587 S"MYROUTER" P"ABCxyz;"" 123"
or if you can't send lowercase characters:

M587 S"MYROUTER" P"ABC'X'Y'Z;"" 123"

At least in the Gcode wiki the examples do include the quotes where they are needed

S"ccc"

Just tried this ... nothing is clearing out the boards eProm config data - is the only thing I can currently ascertain here ...

This didnt work
