And that is where the 'fun' began, how do you update the SD card without network access?

Your PC or laptop may well have a SD card socket already. If it doesn't, you can get USB adapters for SD cards on Amazon, eBay etc.

Another possibility is to update the main firmware directly to 3.3 using the Erase jumper and Bossa. The WiFi firmware you already have should work with RRF 3.3 and when you have wifi access working, you can upgrade the wifi firmware.

That said, it should be possible to get your board connected via WiFi using your existing firmware 2.03. What is the problem you are having?

Hi, thanks for the quick response.

When I issue the M587 S"networkID" P"password" command I cannot connect to the network (can't remember the exact fail message and I'm not near the machine at the moment).

Since I posted I have seen some information that suggests there may be a problem if either the NetworkID or password have lower case characters? - this is certainly true of one of these elements for the WiFi I am trying to connect to.

I will try again wrapping the lower case chars with single quotes and see if that fixes it.

Again, thanks,
Tony

There should be no issue with lower case characters perse and YAT will respect the letter case when sending the passwords, so that shouldn't be an issue either. Do you have any special characters?

Many programs used to send GCodes convert all characters to uppercase. In firmware 1.19.2 and later, within any quoted string you can use a single-quote character to indicate that the following character should be changed to lowercase. For example, M587 S"ABC" P"P'A'S'SW'O'R'D" would specify that the password is "PassWord". Use two single quote characters to represent one actual single quote character in the password or in the SSID. For example, if your SSID is "Pete's network" then enter "Pete''s network".

The use of special characters in the SSID cannot be guaranteed to work. In general it's best to avoid most special characters. Spaces, periods, dashes, underscores, and other punctuation is likely ok, but special characters on the number keys likely are not safe. (@#$%^&*). If you are having troubles adding your SSID, try a simplified version with only letters and numbers.

M587 with no parameters lists all the remembered SSIDs, but not the remembered passwords.

The M587 command will fail if the WiFi module has not yet been taken out of reset. So if the WiFi module has not been started, send M552 S0 to put it in idle mode first.

Getting the specific error message would help.

OK, so I tried using quotes around the lower case characters - you were quite correct - it made no difference whatsoever.

This is the content of the YAT log:
M552 S0
ok
WiFi reported error: no known networks found
WiFi module is idle
M587 S"xxxxxxxxxxxxxxx" P"xxxxxxxxxxx"
ok
M552 S1
ok
WiFi reported error: no known networks found
WiFi module is idle
m552
WiFi module is changing mode

WiFi module is idle
m587
M587: Failed to retrieve network list
ok
Error retrieving WiFi status message: bad reply format version
WiFi module is idle
WiFi reported error: no known networks found
WiFi module is idle

Which, while the response to the initial M587 S"NetworkID" P"password" command (ok) would seem to suggest things are ok; the response to the subsequent M587 (Failed to retrieve network list) suggests otherwise..

I'm sure I'm missing something, just having trouble seeing what!

Really appreciate the suggestions so far..

Thanks,
Tony

Can you send M122 and post the response?

You may need to try reflashing the wifi module.
Send
M552 S0
M997 S1

Then try your commands again.

Another thing to try to circumvent the USB terminal entirely is to create a macro file with the M587 command to add your network, place it on the SD card in the macros folder, and then powering up and using YAT to execute that macro

If you created a text file called addnetwork.g with these commands in it.

M552 S0
M587 S"SSID" P"password"
M552 S1

Then use M98 P"addnetwork.g" to execute it

@phaedrux
Will send response when I can get to the machine - it is in a different location to which I do not have keys, sigh....

As a matter of interest, are you happy to say which time zone you are in?

Thanks,
Tony

Phaedrux

I'm located GMT-6

OK, ran the commands - this attached file shows the result...

Does this information provide any hints as to what I'm not doing/doing wrong?

I have also tried connecting to another network using a completely different router/SSID/password

Can you share the contents of your addnetwork.g macro?

The spam filter is extra aggressive with junior accounts. It should let you copy and paste more text now.

Do either of your network SSIDs and passwords contain any of the special characters or conditions as I had posted above?

speaker2animals

@phaedrux
addnetwork.g:

M552 S0
M587 S"xxxxxxxxx" P"xxxxxxxxxxx"
M552 S1

No special characters in the original network, Exclamation mark (!) used in both SSID and password for the second network...

Both networks running at 2.4GHz

Phaedrux

Couple more things to try.

First, can you download this zip file and extract it on your computer, then manually place all of the bin files into the /sys folder on your SD card.

https://github.com/Duet3D/RepRapFirmware/releases/download/2.05.1/Duet2Firmware-2.05.1.zip

Now using YAT please try sending M997 S0:1 to flash both the main firmware to 2.05.1 and the wifi module to I believe 1.24.

After it's finished, send M122 again to check that the updates have been applied.

Then, send these commands and report back with what they return.

M552

M552 S-1

M552 S0

M552 S1

M587

Then try clearing any saved networks with M588 S"*"

Then try adding your network again with M587 S P and enable the module again with M552 S1.

record any error messages.

@phaedrux
OK downloaded and copied the bin files onto the SD Card. Results attached:

YAT Log.txt

Not sure if the wifi actually updated as it just shows 1.02 or later?

Phaedrux

Ok thanks for trying. I think your wifi module has failed.

When and where did your purchase your Duet?

speaker2animals

@phaedrux One thing I had noticed was that I seemed to get different results executing the commands, - sometimes they appeared to work OK, other times they came back with a negative result,

I must admit, from what I had seen on the forums, I had begun to suspect I have a hardware problem.

I got the Duet about 3 weeks ago as part of an Ooznest Workbee CNC kit - I'll engage with them to get it replaced.

Many thanks for all your assistance - very much appreciated by someone who is trying to get their head around what is, to them a completely new area!

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out. Then Oozenest will be able to take care of the replacement.
