Error: Failed to initialise WiFi module, code -10 on 2.05

  • Hello.

    After a few months (since march due to covid), I am back at my university working on a 3d printer with duet2 wifi. After I turned the board on, it all went fine, but after about 2 minutes it disconnected. No matter how many times I have reset the board, it still won't connect. The Wifi module light flashes once very briefly. When I try M552 S0, it throws the error shown on the title. I tried updating from 2.02 to 2.05, and everything went correctly but I still get the same error. What does error -10 mean? I will revert to my previous install, but I still don't know what happened.

    Thank you.

    try updating (or re-flashing) the wifi firmware? see this post to get some more details if that fails

    How did you update from 2.02 to 2.05?

    Download these two files and place them on the SD card in the /sys folder with your PC.

    Rename DuetWiFiServer-1.23.bin to DuetWiFiServer.bin

    Extract this zip file to the /www folder.

    Now put the SD card back in the duet and power up via USB and send M997 S0:1 in the console to install the main and wifi firmwares.

    Then send M122 again after it reboots and post the result.

  • Hello again @bearer @Phaedrux . I don't have access today to the 3D printer, I will try your recommendations tomorrow morning but I just wanted to maybe help clarify something.

    Wifi worked perfectly until yesterday, where mid-homing it just disconnected. Every time I send M552 S0 or S1, it gives the error Error: Failed to initialize WiFi module, code -10.

    Since I saw there were some updates to the firmware, I tried installing them to see if that fixed it. However, the issue persisted.

    I had the problem before I updated, so I don't think the update was the issue. However, I don't know enough so I will try reinstalling it and check again. Thanks!

    How old is the Duet and where was it purchased?

  • It is about one year old. I would need to contact the sales department for the exact payment date, but I can confirm we received the package on October 18th, 2019. Judging from some emails, it was probably purchased on September 27th, 2019. It was purchased from Filastruder. However, it has been in storage since March, when the pandemic hit. Do you think it got damaged while unused? That would suck, I really hoped it was a software issue.

    Well it does seem to be a fault in the module. Reflashing the wifi server firmware appears to work correctly, but the error persists.

    Unfortunately you're outside of the 6 month warranty, but we may be able to provide an exchange at reduced cost. Please contact and explain the situation and include a link to this forum thread.

    Alternatively, if you're in a situation where you have access to PCB soldering tools you may be able to replace the wifi module yourself, or have someone do it. The modules themselves can be obtained rather cheaply.

  • Well, that is unfortunate. I will send an email to that address as you suggested, thank you for the help.

    I do have access to soldering tools. Haven't worked with SMD before, but I have other scrap boards I can practice with before I replace this, or I can ask someone else perhaps. Are there any instructions on how to replace this? As in, specific to the duet? Or do I just find the module itself and solder it back on and then run M122 and that's it?

    Thank you for the help!

    See here:

    That should give you an idea of what's involved to decide if it's a worthwhile option.

  • You might be able to replace the wifi function with a raspberry pi as well, but the required firmware RRF3.2 isn't released yet so it might be a bumpy road.

    You'd likely not need to remove the Wifi to use the same signals for the SBC interface (depending a little on how the wifi module has failed) lots of details here

    This post shows a no-solder approach for the wifi board (albeit a few crimps are needed):

  • administrators

    Is the DuetWiFiserver.bin file that you uploaded to the WiFi module definitely the DuetWiFiServer.bin file version 1.23 from a recent release?

    It's worth trying to install the WiFi firmware again. The firmware upload protocol defined by the manufacturer of the WiFi module does not include error detection, and I have known it to appear to succeed but to leave the WiFi module running corrupt firmware.

  • @Phaedrux that looks great! thanks. I have access to ESP-12E, does that work or does it have to be ESP-12S? I guess I can get an Adafruit HUZZAH or maybe a NodeMCU with the ESP-12S and salvage the module from that board, but if the E version is compatible that would be ideal.

  • @JairoRB said in Error: Failed to initialise WiFi module, code -10 on 2.05:


    12E will be fine if the certifications on the module is acceptable for you (fcc/ce/ul etc)

  • @dc42 I am as sure as I think I can be, for what it's worth. I flashed for myself at first from github, then from the link provided by Phaedrux and then again from github, making sure it was indeed version 1.23. After running M997 S1, it completes no problem but the issue comes up.

    Is there a way to make sure it is the hardware side?

  • @bearer Excellent, thank you
