Problem with escape characters for password for Wi-Fi card.

Schickfus

I used

M98 P"Gcodes/Wifimacro.g"

; wifimacro.g
; tell the Duet to connect to the wifi
;M118 S"Wifimacro turn off Wifi"
M118 S"Wifimacro turn off Wifi"
M552 I1 S0 ; Turn off the wifi module
M588 "*" ; forget all current SSID networks
M587 S"SurfSpaceGuest" P"Test"
M552 I1 S1 ; turn the wifi module back on
;M118 S"Wifimacro turn on Wifi"
M118 S"Wifimacro turn on Wifi"

Remove the I1 from your M552 commands. Are you using an SBC?

You're missing the S in front of the "*". It must be M588 S"*"

@Schickfus i would suggest you shouldn't be using the I1.
Just use M552 S0

Edit: reading further, I should only be used when in SBC mode

The I1 is a required parameter to M552 when using the optional WiFi interface on the MB6HC board, so select the wifi interface. The default is I0 which is the Ethernet interface.

So I am connected via the serial tool on a Mac to the board.

I recall reading in previous posts that Macs have a habit of substituting "smart quotes" for plain double quotes. Are you sure that hasn't happened?

Schickfus

@dc42

No I have done some testing.

M587.1

M587.2

And gett ssid string in the beginning chopped offed. Does this mater.

That's a known issue in RRF 3.5beta2, fixed in the forthcoming beta3. It's only the reported SSID that gets truncated, not the stored SSID.

@dc42

Is there a way to know that I have installed the right wifi code?

The files:
DuetWiFiServer_32S3.bin
DuetWiFiServer.bin

Schickfus

@dc42

I guess that makes my question obsolet.

@Schickfus the correct one for the optional wifi module on the MB6HC version 1.02 is DuetWiFiServer_32S3.bin. It should select that one automatically. If in doubt, make sure that the /firmware folder on the SD card contains that one and not the other one, and send M997 S1 to update the wifi module. The latest version is at https://github.com/Duet3D/WiFiSocketServerRTOS/releases/tag/2.1beta3.

However, if the wifi module is responding to requests at all, you almost certainly have the correct firmware installed, although perhaps not the latest version. If you send M552 I1 S0 followed by M122 then the WiFi section of the report should include the WiFi firmware version.

Schickfus

@dc42

It is the right. WiFi firmware version 2.1beta3

M587 S"Surf" P"=U2raA44Ae*”

The closing quote at the end of the password in that line is indeed the wrong sort of quote, it's not a straight quote. The command provokes the reply "Error: M587: control character in string". The command is accepted if I replace the closing quote by a straight double quote.

Try sending those commands from the console, but:

after the M552 I1 S0 command, wait for the "WiFi module started" message
change M558 "" to M588 S""
wait at least 10 seconds after the M588 command, it has to erase the flash file system
make sure that your terminal emulator doesn't change the straight double quotes to smart quotes

If you want to send them from a GCode file instead, you will need to add G4 delay commands after the M552 and the M588.

@droftarts the gcode docs need updating to reflect that then

@jay_s_uk I've updated it.

Thanks!

I got it to work. Just switched to a PC and dropped using serial tool on Mac and it all started to work.

Thanks for the G4. This will improve the code.
