Cannot get WIFI to work on a new Duet3D WIFI

A Former User

Breifly looked at the 2.03 bundle and the wifi server version was 1.23, but not sure if there are better ways to tell which version the binary is, but on linux strings and grep usually works, not always as simple as grep version though.

bearer@rama:/tmp  $ strings DuetWiFiServer.bin  | grep version
version=1.23

Are the SSIDs of your networks exactly as M587 reports them? SSIDs are case sensitive. Are they definitely broadcasting on 2.4GHz, and not hidden?

Maybe Wifi issues should be accompanied by a screenshot from an android/iphone app that shows wifi networks, channels, encryption types and signal strengths in the same location as the Duet. Its been a while since I've looked at those - but others may have up to date reccomendations.

Error retrieving WiFi status message: bad reply format version
[ERROR] Error retrieving WiFi status message: bad reply format version

as jeff points out it suggests wrong versions, @dc42 would the firmware issue those messages if the versions were right but no networks were found, i.e. empty replies?

No. The only known reason for that message is mismatched firmware versions, however there have been a few reports of it, so I am starting to suspect a bug. Recommended workaround when you get it: send M552 S-1, then M552 S0, then try the original command again.

It looks like I got it to work. Here is what I ended up doing:

The M552 S-1 followed by M552 S0 seems to reset the WIFI unit and now it reports the following with the M122 command:

>>> M552 S-1
SENDING:M552 S-1
WiFi module stopped
ok T0:2000.0 /0.0 B:2000.0 /0.0
>>> M552 S0
SENDING:M552 S0
WiFi module started
>>> M122
SENDING:M122

I can now see the WIFI firmware version as 1.23.

On WIFI Frequency. I have separate SSIDs for difference Frequency sets. So yes these are 2.4GHz networks.

On the issue of Wifi SSIDs: They are not the same. There are lowercase letters in the SSIDs and I enter them as such with the M587 command. But when I check the list with the M587, all the characters are upper case. The same is happening to the Passwords. I discovered this when I added an SSID with all uppercase letters into my WIFI access point but with lowercase letters in the password. I was getting "WiFi reported error: Wrong password while trying to connect to JEFFPIXEL". I then created an uppercase password and now the system connects. The sequence of commands that I used are as follows:

M552 S-1                          ---Stops the WIFI Module
M552 S0                           ---Starts the WIFI Module
M122                              ---Checks the status of the board (WIFI status at the bottom)
M588                              ---Cleared all old SSIDs
M587 S"" P""                      ---Entered the new SSID with uppercase SSID and password.
---I made sure to have a WIFI SSID and Password that matched all uppercase letters.
M552 S1                           ---Connect to WIFI
---(After a few seconds)
M122                              ---Check status of WIFI at the bottom

The last command yielded the following for the WIFI section:

- WiFi -
Network state is running
WiFi module is connected to access point
Failed messages: pending 0, notready 0, noresp 0
WiFi firmware version 1.23
WiFi MAC address dc:4f:22:6e:6f:a8
WiFi Vcc 3.42, reset reason Turned on by main processor
WiFi flash size 4194304, free heap 25296
WiFi IP address 10.240.0.240
WiFi signal strength -51dBm, reconnections 0, sleep mode modem
Socket states: 0 0 0 0 0 0 0 0

I can now ping the board on the network.

Thank you

Hi,

Just out of curiosity why do you have separate SSIDs for different channels - I guess that is what you mean by "frequency sets".

That's because you are using the wrong program on your PC to connect via USB. The reason we tell you to use YAT (if using a Windows PC) is that common GCode senders such as Pronterface convert everything you enter to uppercase.

Please check that you don't have any M587 or other network-related commands in config.g, other than M552 S1 to connect to the access point.

It just makes it a lot easier to know if you are connected to 5Ghz or 2.4Ghz. On my cell phone I can forget the 2.4GHz name and just connect to the 5GHz name. That way I know I am always on 5GHz. It really is just an easy diagnostic tool. It also allows you to know if any device can only connect to 2.4GHz, if all that is available is the 2.4GHz SSIDs.

Thank you for the info on YAT.

I only had the M552 S1 in the config.g file at first (No M587), while the issues were occurring.

I have since the last test added the following:

M552 S-1					   ; Stop WIFI Module
G4 P2000				           ; Wait 2 seconds
M552 S0						   ; Start WIFI Module
G4 P2000				           ; Wait 2 seconds
M552 S1

And now it boots and connects to the network without any issues.

Let me know if I should make any changes.

Thank you!!!

I am surprised that adding those commands makes any difference, because the M552 commands get deferred until config.g has completed. Or at least, that's what is supposed to happen. Are you sure it still doesn't work with just M552 S1 in config.g?

I removed the commands and just have M552 S1 now and it does still connect. I guess the M552 S-1 followed by M552 S0 was only needed after the firmware upgrade.

Thank you.
