Converting the Duet WiFi to use an external antenna



  • Yes, it is low. But, as said, real transmissions work much better and faster, now. And no more disconnection.

    I will make tests with different channels (I think I'm on channel 1 - the router is in auto and chose this one).



  • Hi!

    I have WiFi signal strength -61dBm in three meters from the router. The ESP-07 has a very very weak antenna ((
    I will change to ESP-07S or connect external to ESP-07.
    Laptop, iPhone, Nokia etc. - everything works fine.



  • I used a wifi analyser on my phone, and noticed that there where 3 other AP on channel 1. In fact, it depends where I am in the house, and on the AP side, they are not detected. So the AP chose this channel. But on the printer side, they where as powerfull as my AP!

    I moved to channel 3, unused by other wifi AP, and I now have -66dB strength…



  • Will this be available as a build option?



  • ESP-07S sold out in RS-online 🙂 how thats possible



  • Hi, i have a problem since i changed the Module.
    I can only connect to the Duet Wifi in Accesspoint mode. If i change it to M552S1 it only says: Wifi reported error: no known networks found.
    The wifi is defenitly present.
    Did flash the right firmware files main as also the Wifiserver one.
    Running 1.21

    Anyone a clue why this could be?



  • Got the Problem solved.
    David, i think the firmware 1.21 has a problem with loading the M587 with the Router data from the config.g to the remembered list.
    Got my problem solved with Repetier host, did send the M587 with ssid and password via g-code console.

    How did you send the M587 command originally?



  • Via the config script


  • administrators

    Sending M587 in config.g isn't going to work, because the wifi module doesn't get enabled until the end of running config.g. That's why I suggest using a macro to send those commands.



  • Ok for the next time i will do that.
    Should be mentioned in the Wiki.
