  • I have used this code before but I am interested in commanding through terminal as bluez was created to communicate to BLE. I have worked with other BLE and it worked but I don't know why I can't find voltage on the pins of espruino.

    'I have used this code before'

    What code is being referred to as there isn't any provided in this thread?

    Has the WebIDE been used as a double check?
    How are the Javascript commands being sent to the MDBT42Q?

    There really isn't enough detail to make a definitive response. Not familiar with bluez.

    'I don't know why I can't find voltage on the pins of espruino'

    Let's try this way.

    Q1: Are we working with the module or the breakout board?

    http://www.espruino.com/MDBT42Q#pinout

    Q2: What voltage is being applied to power the MDBT42Q?
    Q3: . . . and to which pins, both power and ground?

    Q4: Which tutorial(s) have been attempted and what were the results?
    Q5: What was the result of digitalWrite() and pinMode()from post #2 above?
    Q6: What was the result of both examples from post #6 above?
    Q7: If breakout board, were the LED's able to be illuminated?
    Q8: If breakout board, what is the voltage at the pin adjacent to D14 labeled 3.3?
    Q9: If breakout board, what is the voltage at the pin adjacent to D7 labeled Vin?

    The responses to the questions above will assist in determining if we are dealing with a hardware or software issue.
