• I know the problem is on my side ....
    so maybe you can guide me to understanding
    all I want to do is connect from the PI to the device and turn on\off led1

    this is what I'm missing :
    1.up until now when I wanted to turn LED1 on I wrote
    LED1.write(true)
    and now you say I need to write 'LED1.set()\n' - do I need to add true\false ?

    1. after I have connected to the device , why can't I see the data I'm sending to him , is there any way to write something to log in order to see where is the problem ?
      all I can see is -> Bluetooth
      I'm sending sample data once every 10 seconds , and I can't see anything - why?

    I read somewhere I can use Node-RED for creating a project and connecting with the MDB42Q
    I mange to create a connection and I'm sending data from it - but again, I don't see anything on the device - the led is not tuen on\off
    do you have an example\guide for it?

  • you say I need to write 'LED1.set()\n' - do I need to add true\false ?

    no, https://www.espruino.com/Reference#Pin

    -> Bluetooth is printed when output console is switched to bluetooth, this indeed happens by default when you connect. When you disconnect you will probably see -> 'name your previous console'. Often this is what you want when you connect to the device via https://www.espruino.com/ide/ or espruino cli command. You can override this behaviour as per https://www.espruino.com/Reference#l_E_s­etConsole but if you keep console as it was you cannot send commands like the LED1.set() to console via bluetooth connection.

    and I can't see anything - why?

    output goes to bluetooth console but you probably don't read it at all

    do you have an example\guide for it?

    I think I linked more than enough guides already and it doesn't look like it helped
