    Hello!
    I am trying to connect external GPS sensor to UM7.
    UM7 pinout
    I connect TX2 from IO Expansion Header to PPS from GPS sensor,
    RX2 from IO Expansion Header toTX from GPS sensor
    I set the same baud rate transmit and receive in UM7 and GPS sensor (115200/115200).
    Messages from GPS sensors have the following form:
    $GPGGA,153547.00,5620.9032,N,04118.9628,E,1,03,6.0,00064.0,M,0010.1,M,,*6A
    $GPGLL,5620.9032,N,04118.9628,E,153547.00,A,A*68

    $GPZDA,153547.00,22,06,2016,+03,00*4C
    But the fact is that the sensor does not accept data from the GPS and NMEA Health Packet – $ PHRH in the field responsible for the GPS all the time there is 1.
    What tell about it?
