New Board Can't Connect to Wi-Fi.

Sadly, no joy.

When I use the 587 command, I get the following: "Remembered networks:<lf>TNCAP2FCC19<lf>My Network Name<lf>your=network-My Network Name Fa<lf>your-network-My Network Name Fa<lf>My Network Name <lf>My Network Name 2<lf>ok<lf>"

When I type the 552 S1 command, I still get: "ok<lf>WiFi reported error: no known networks found<lf>Wifi module is idle<lf>"

Hope I'm not being dense…</lf></lf></lf></lf></lf></lf></lf></lf></lf></lf></lf>

tonydacrow · 31 Mar 2018, 16:41

The latest: now an M587 command reports "M587: Failed to retrieve network list<lf>ok<lf>" This is after an M552 command that shows WiFi module idle. Seems like I have a defective board. Anyone else have any ideas before I return the board as defective?</lf></lf>

Please run M122 and check that the versions of main firmware (listed near the start of the response) and WiFi firmware (listed under the "Network" section) are compatible.

I had Firmware version 1.19.2 but upgraded to the latest 1.21 via SD card in the hopes that would help. When I run M122 I get the following:

I noticed that in my last post, I exceeded the number of bytes per line which truncated the command reply. Here is the full display with the M122 command:

Please put LF as line ending (<eol>) in YAT, this will give you proper printouts</eol>

Thanks for the tip, Whosrdaddy.

You are running main firmware 1.21 but WiFi firmware 1.19.2. Please upgrade your wifi firmware to 1.21. As you can't connect via WiFi at present, you will need to move the SD card to a PC, copy the new DuetWiFiServer.bin file to /sys, eject or safely remove it, put the card back in the Duet, restart the Duet, and send M997 S1.

After that, if you run M122 it should report "WiFi firmware version 1.21" in the Network section.

tonydacrow · 4 Apr 2018, 04:39

Sadly, still no joy.

I updated both firmware and wifi drivers to 1.21.

Yet, when I run the M552 S1 after setting-up the network with the M587 S"MY NETWORK NAME" P"MY PASSWORD" command, I get:
m552 s1

ok

My wifi network has an apostrophe in its name. Perhaps that could that be the problem? Any additional thoughts? At this point I'm close to stumped…

Phaedrux · 4 Apr 2018, 04:43

Never trust an apostrophe and anything to do with computer naming.

dc42 · 4 Apr 2018, 08:48

Apostrophe in a quoted string forces the following character to lowercase. So you need to use two apostrophes to represent one, in both SSIDs and passwords.

I suggest you send M588 "*" to delete all those dud remembered networks, then send the M587 command using two apostrophes in the SSID this time. Then send M587 without parameters to check it is remembered correctly.

tonydacrow · 4 Apr 2018, 12:14

Huzzah! That was the issue; a silly little apostrophe in the network name. My Duet Wifi is now connected to my network.

A big THANK YOU to all who helped, but especially to you dc42 for you patience and generosity with this issue!

dc42 · 4 Apr 2018, 18:58

No problem, it was you who suggested the apostrophe might be the problem and made the diagnosis easy. I've updated step 7 at https://duet3d.dozuki.com/Guide/1.%29+Getting+Connected+to+your+Duet/7?lang=en to cover the case of apostrophes in the SSID and password.
