  • Hi @hekras , @mhvelplund and @raute_at

    I have added a quick wifi tutorial on, that explains the steps to do a HTTP GET request.

    Its only HTTP, HTTPS is coming later - its more complex.

  • Just got my mono and looking forward to using it with the HTTPS. Any chance you need a use case for it? I'd love for it to connect to the Maker channel on IFTTT, that would enable loads of functionality for Mono.

  • @aabinks I have replied as a new topic.

  • Hi @stoffera, I have tried following your WiFi tutorial, but it fails when this line is added:


    And by "fails" I mean that the display flashes and the speaker beeps twice.

    I have added the "return true;" line that @raute_at mentioned in this thread:

    Otherwise, it failed on the ModuleSPICommunication constructor.

    Any idea what could be wrong?

    Here is all the code I have added to the Hello World program:

    // app_controller.h
        mbed::SPI spi;
        redpine::ModuleSPICommunication spiComm;
    // app_controller.c (contructor)
        spiComm(spi, RP_SPI_CS, RP_nRESET, RP_INTERRUPT)
    // app_controller.c (monoWakeFromReset)

    Also, is there any way to check that my Mono actually supports WiFi? I should have the Mono Maker with WiFi and Bluetooth, but there is no indications on the box.

    Hi, the problem is in the Makefile that comes with monomake. Until we get that fixed, you can make sure that the build directory in your project is clean by simply deleting it. On MacOS/Linux you would do like this:

    $ rm -rf build/

  • Hi @jp, I have already tried that, but unfortunately it didn't help.

    It did solve another problem I had, though.

    You can identify the model of your Mono in several ways. On the box it says which model you have:


    On the back of Mono, it says which model you have:


    Inside Mono, if there is a big shiny encapsulation, it is the Wifi module:


  • Hi @jp, thanks.

    I have the same Mono maker m3 (and I also have the RF shield inside) so I guess that's not the problem, but it's good to be sure.

  • @emil.melgaard Hi, just out of curiosity. Did you manage to solve the issue (crashing when initializing the wifi module)?
