    Hi,

    I mounted the BerryGPS-IMU on a Raspberry Pi Zero W.

    I’ve got /dev/serial0, but no NMEA data (cat or gpsmon)

    output of “gpspipe -r” :

    {“class”:”VERSION”,”release”:”3.16″,”rev”:”3.16-4″,”proto_major”:3,”proto_minor”:11}
    {“class”:”DEVICES”,”devices”:[{“class”:”DEVICE”,”path”:”/dev/serial0″,”activated”:”2017-11-01T18:33:40.693Z”,”native”:0,”bps”:9600,”parity”:”N”,”stopbits”:1,”cycle”:1.00}]}
    {“class”:”WATCH”,”enable”:true,”json”:false,”nmea”:true,”raw”:0,”scaled”:false,”timing”:false,”split24″:false,”pps”:false}

    Regards,

    Adrien

    We do test every BerryGPS-IMU before they leave.

     

    Can you do a loopback on the serial lines?   Connect RX and TX together with a jumper cable. These is physical pins 8 & 10.   And then run minicom.  When you type, you should see the characters in minicom.  If they dont appear, it means serial is working correctly.

    Install minicom;
    sudo apt-get install minicom

    Start minicom;
    minicom -b 9600 -o -D /dev/serial0

     

    You may need to kill gpsd first;
    sudo killall gpsd
