Thomas asked 2 months ago
Hello,
i’ve got the “simpleRTK2B – 4G NTRIP Starter Kit”.
(if I understand correctly uart2 is used by the NTRIP module)
I want to get a NMEA-Signal on the UART1 like this:
$GPGGA,114750.98,4919.8758815,N,01203.5656652,E,4,08,1.0,100.0,M,50.0,M,,*69
$GPVTG,127.00,T,127.00,M,000.00,N,000.00,K,S*31
$GPGSA,A,3,01,02,03,04,05,06,07,08,,,,,1.0,1.0,1.0*3B
$GPZDA,114751.167,24,06,2022,00,00*53
but i only get hieroglyphs on UART (USB-RS232-Adapter 3.3V tolerant).
I also connected IOREF to 3.3V

Do you know where my configuration error is?

Check that you connected also GND to your adapter. If you can share how is your connection being done and which adapter are you using we can try to help. Also confirm which baudrate are you expecting data on UART1

Check you’re using 38400 baud (default for ZED)
Check with uCenter (Classic 21.09), get View -> Packet View, make sure it’s not outputting UBX packets instead.

Well, i found my mistake. I used a defect UART-RS232 converter. I replaced it and now it works.
 
Thank you for your help.
