    I have the exact same issue with a set of new nodemcu :(

    Fist I had a lot of kernel panic on my mac due to a faulty driver. I had to reinstall my system.

    Now the espruino IDE is not communicating with the board :'(

    Connected [object Object]
    Found a prompt... great!
    >>> Sending...
    ---> "\u0010console.log(\"<\",\"<<\",JSON.str­ingify(process.env),\">>\",\">\")\n"
    >>> Sent
    WARNING: No result found - just got ""

    I have an other nodeMcu board that's working perfectly (I guess it's an other model)

    Issue resolved :)

    I tried a digital pin without any success :(

    I tried an other HC-SR501 and it worked. So my sensor was definitely broken.

    here the code that's working :

    setWatch(function() {
      console.log("Movement detected at : ", Math.floor(Date.now() / 1000) );
    }, NodeMCU.D6, {repeat:true, edge:"rising"});

    Hi MaBe,

    Thanks for the heads-up :)

    I'm gonna try this.

    Hi everyone, I'm trying to read a HC-SR501 with my nodeMCU but I struggle a bit :(

    Wiring :

    VCC to vin (5V)
    OUT to A0
    GDN to GDN

    I tried :

    setWatch(function() {
      console.log("Movement detected");
    }, NodeMCU.A0, {repeat:true, edge:"rising"});

    Never got any detection

    I tried

    setInterval( () =>{
       console.log( analogRead(NodeMCU.A0) );
      // print 0.00097751710 all the time

    I swapped the sensor for a water level sensor and console.log( analogRead(NodeMCU.A0) ); and the water level is detected normally.

    Did I miss something ?

    Thank you a lot for your help :)

    Hi guys as it was a bit dificult to find a straightforward solution I just write a quick recap on how to fix de issue.

    Board : NodeMcu ESP8266 ESP-12E CP2102

    computer : Mac OS Sierre 10.12.6

    Error that I got "Wifi module not found" and impossible to comunicate with the board.

    How I fixed it :

    I reflashed the board with this settings :

    files are from the folder /espruino_1v94/espruino_1v94_esp8266

    esptool.py --port /dev/cu.SLAB_USBtoUART --baud 115200 write_flash --flash_freq 40m --flash_mode dio --flash_size 4MB 0x00000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0x3FC000 esp_init_data_default.bin 0x37E000 blank.bin

    NB : You maybe have to change the port /dev/cu.SLAB_USBtoUART

    Have a nice day and enjoy
