GuestHello!
I am trying to connect external GPS sensor to UM7.
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
$GPGSA,A,2,13,05,70,,,,,,,,,,7.9,6.0,5.1*3F
$GPGSV,3,1,10,70,33,037,36,71,54,110,,72,21,166,,77,23,264,*7D
$GPGSV,3,2,10,78,27,324,,79,08,003,,85,07,105,,86,58,091,*76
$GPGSV,3,3,10,87,56,303,,88,08,291,*76
$GPRMC,153547.00,A,5620.9032,N,04118.9628,E,000.43834,073.6,220616,,,A*54
$GPVTG,073.6,T,,,0000.4,N,0000.8,K,A*4E
$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?11 March 2020 at 1:43 pm #9103Finn
ParticipantSame problem here.
RX2 is connected to the TX from the GPS
NMEA Masage from the GPS:
$GNGGA,135612.00,5082.09710,N,00608.13588,E,1,12,0.61,65.7,M,46.8,M,,*7CThe RSX-UM7 health packet still contains a 1 for no GPS signal.
The GPS pose packet is also empty.11 March 2020 at 1:43 pm #9104Finn
ParticipantMy IMU NMEA massages:
$PCHRH,35.031,00,00,0.0,0,0,0,0,0,1,0,0,0,*44
$PCHRG,35.031,0.000000,0.000000,0.000,2.24,2.97,18.79,*5B11 March 2020 at 1:44 pm #9105Finn
