@droftarts Thank you for your help. Unfortunately, I am still receiving the same error even with the older 1.27 Wifi firmware. Here are some pictures of my board.

I assume the board must be somehow damaged? But it seems strange that the firmware upload for Wifi module completes successfully.

@droftarts Just tried suggested steps. Flash 3.6.0-beta.3, upload correct DuetWifiServer.bin on Sd card. Followed by succesful upload process to DUET2. After M552 S0 it is still returning: ok<LF>WiFi module started<LF>WiFi module started<LF>WiFi module started<LF>WiFi module started<LF>Error: failed to initialise WiFi module: bad request format version<LF>

@droftarts Thank you! I will give it a try. Originally, it was running on some 3.x.x version I am not sure which one. I was used to upgrading it over DWC. But I gave it to my friend, who tried upgrading fw to the newest version over YAT and here we are. When this problem occurred, I tried 1.19. and 2.0.5 and the latest 3.6.0 (have tried also a few versions between). I always flash a duet using BOSSA with the correct firmware + install the correct wifi module firmware over YAT (the same version as a duet firmware). I didn't change the wifi module.

This afternoon I will try the suggested steps and let you know. Thanks for helping.

Hi,

I am trying to make wifi module work. I have duet 2 Wifi board. It was functional, but after SW update I was unable to start wifi module using M552 S0. I have tried many different versions of DuetWifiServer and Duet FW. Latest I tried using 3.6.0. beta with the latest wifiserver FW. response on M552 S0 is: "ok<LF>WiFi module started<LF>WiFi module started<LF>Error: failed to initialise WiFi module: bad request format version<LF>"

When I was tried FW 2.0.5 with according wifi FW I received error code -2 during the wifi module initialization.

I am completely stuck. I have tried also erasing and clean install with bossa, but without success. Is the board dead?

Thank you very much!
