Error M587:Failed to add SSID to remembered list.

@Hiroaki Connect via USB, send M552 S-1 to turn WiFi off, then M552 S0 to turn it on, but in idle mode, then add the SSID with M587. Finally, enable WiFi with M552 S1.

@jay_s_uk Hello Thank you for your comment.
I have done it, but still the same...

Hiroaki

@droftarts Hello. Thank you for your comment, I did it.
When I send M552 S-1, the light of the wifi module was turned off.
When I sent M552 S0, it's turned on again.
But when I sent M587 S"ooxx" P"ooxx" it's still the same...

Only One I can't get is "Idle mode" I put....

Hiroaki

@Hiroaki Sorry "Idle mode" you put.

droftarts

@Hiroaki Can you send M122 and post full reply. How old is the Duet?
And what board revision? eg 1.02, 1.04c

Ian

Hiroaki

@droftarts
Hello The board is quite new.
I bought it about two months ago, but as I have been building the machine, it's still like new.
The answer of M122 is as floows. Thank you.

@Hiroaki The version is 1.04.

@Hiroaki The M122 reply has been cut off, and the WiFi diagnostics is missing. If you are connecting with YAT:

Set YAT to use <LF> as the end of line character. This will improve the readability of the messages coming from the Duet. Click "Text Settings" in the "Terminal Settings" and change "EOL sequence:" to <LF>. Click "OK" to close Text Settings. Click "OK" again to close Terminal Settings.

@Hiroaki Send M552 S-1, then M122, M552 S0, then M122, and M552 S1, then M122. This is what the response from my Duet 2 WiFi looks like (you can just copy the WiFi part at the end):

If you're not getting something similar, I'd guess that the WiFi module has failed. The usual reason for this is a power surge on the 3.3V line; the WiFi board and SD card are often the first to fail if this has happened, but can protect the main processor from failing.

It is possible that the WiFi module firmware has not flashed correctly. Try downloading a fresh DuetWiFiServer-1.23.bin from https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1 and upload it to the 'sys' folder on the SD card, then send M997 S1.

Hello @Hiroaki... I have had this issue myself a few times. The advice here did solve it; but I had to do it a couple of times. Re-flashing the firmware more than once might be necessary. I also found that in BOSSA, using the setting "erase all" seemed to yield the best results. Good luck to you!

Hiroaki

@droftarts Thank you. As it's getting late night, I will do it tomorrow.
By the way do you think it's possible to change the wifi module ?

Hiroaki

@beachtec Thank you. I will try tomorrow. It's 0:21AM ...
Best Regards

Hiroaki

@droftarts
One question .
Upload Duetwifiserver-1.23.bin to the SYS not WWW folder?

Yes, firmware updates go in the 'sys' folder. The 'www' folder is for DWC components.

Hiroaki

@droftarts ok Thank you.

DuetWiFiServer-1.23.bin

I think you'll need to rename the file and remove the -1.23 part so that the final file name is just DuetWiFiServer.bin

Hiroaki

@droftarts Hello
Thank you so much.
I could solve the problem.
sent M997 S1 and then ok.
I appreciate that.
Thank you

Hiroaki

@Phaedrux Thank you.
This was also helped me !
Thank you.
