I connected the Ardusimple RTK2board base breakout board to PC through USB . Then I configured the base module in fixed Lat./lon. coordinate mode using UBX-CFG-TMODE3. I also enabled USB for RTCM3 msgs.1005,1074,1084,1094,1124 in UBX-CFG-VALSET window using CFG-MSGOUT-RTCM3X type1005 USB,etc. The USB is also enabled for RTCM3 message in IN & OUT protocols in CFG-USBIN/OUTPROT-RTCM3. In CFG-TMODE-MODE also,the receiver reads ‘ true’. But the U centre fix status does not show TIME MODE & also the RTCM messages are not seen in Messages-RTCM3-1005,etc. How can I resolve these so that I can send RTCM correction stream from the base module.
Could someone post the basic configs shipped on base and rover, and xbee parameters used as well, please?
Enable UBX-NAV-PVT to see mode information
UBX-NAV-PVT window does show position fix type as TIME but in U – centre data view window shows fix mode : 3D ,not TIME.
Also even after CFG-USB-IN/OUT PROT is enabled for RTCM3x msgs. & also enabling CFG-MSGOUT-RTCM3 1005,etc., no RTCM messages is seen in UBX-RXM-RTCM or RTCM3-1005,1074,etc. windows. It is not becoming possible to send out RTCM messages.
I could get the RTKFIX as suggested but the USB port is engaged in U-centre whereas I need a RTKFIX NMEA COM PORT for field data collection software Arcpad. So,do you suggest an UART to USB adapter to get the RTCM correction stream into the rover module & use the rover board USB for using as COM PORT for data collection software ?
Can you explain again your setup and issue? Do you use a pre-configured base and rover from ardusimple? If yes you only need to set the fixed position to the base, and the rest of the system is already pre-configured to send corrections.
Note that the connection between base and rover is done through UART2, this is the port where RTCM messages need to be enabled.
The issue is resolved. I am able now to send RTCM stream from base to RTK2go.com NTRIP server & then receive it in the rover in NTRIP client window & get RTK fix status,but my USB port gets engaged & I want to use RTK fix NMEA msg. in another data collection software COM PORT. I want to use XBee USB port for getting in rover RTCM correction stream into module UART2 from Lefebure NTRIP client. For using XBee USB for this purpose, I have the following problem, please solve them:
1- how to ‘ bridge’ TX/RX pins ? What is meant by bridging ? Do I need connect board TX2-XBeeTX & board RX2-XBee RX or the other way ? Which ground pins to be connected ?
2- How to power the pins ?
3- I will not connect any device to XBee USB. I will just use it to have a free COM PORT to get correction stream in Lefebure NTRIP client. Can I use it for this purpose ?
I would highly appreciate if you can explain board UART2 TX2/RX2 ————XBee TX/RX ,GND & power pin connections pictorially by diagram for using XBee USB.
P.S., I am not going to use XBee USB for using radio but for COM PORT for connecting to Lefebure NTRIP client for getting RTCM correction stream.
