Can you extend your explanation?
1. Which product do you have? only simpleRTK2B or MR/LR kit?
2. How do you enable UART2?
Thanks your supports. I purchased the simpleRTK2B+heading – Basic Starter Kit IP67 December 2019 from japan.
A few weeks ago ,I could connect Xbee on SimpleRTK2B to send RTCM3 ,to Xbee on SimpleRTK2lite.
Yeseterday I can not connetct Xbee on SimpleRTK2B, gps->Xbee LED not lighting,but xbee->gps LED liting.
my configuration schemozzled ,some times I tryed to revert default condition at ubx-cfg-cfg .but gos->Xbee not lighting.
So I downloaded your SimpleRTK2B-master from git, https://github.com/ardusimple
and setting the “srtk2b_bluetooth_FW_HPG112” FILE
Then gps->Xbee ligting Started !!! PC Xbee can recieve SimpleRTK2B output UBX+NMEA .
Tnak you for your master configuration files.
※I want to measure ski heading ,but I repeated failure Moving Base configuration ,NAV-RELPOSNED does not work.
Please show me, easy set up for heading. SimpleRTK2B+SimpleRTK2lite configuration.
My skiing trace movie is uploaded YOUTUBE,But low accuracy,https://youtu.be/vO00OPYa86g
All configuration files are available here: https://www.ardusimple.com/configuration-files/
If you use the simpleRTK2B+heading configuration files it should be plug-and-play to receive RELPOSNED with heading on the large board.
I checked your video, and I see 2 challenges:
– Limited sky view from the antennas, this will limit accuracy.
– Limited distance between 2 units, this will also make difficult heading calculation.
– High dynamic conditions and vibration (skier).
Recommended antenna distance for sub 1 degree accuracy in low dynamic conditions is 50cm.
Good luck with your project, hope we can see some results soon.
Thank you quick response, I try to set the confgure files,
I’m sorry for the rudimentary question
I have ansure items int https://www.ardusimple.com/configuration-files/ PAGE as below ,
1;MB (Moving Base) of a simpleRTK2B+heading kit
What this kit connection, Is SimpleRTK2 lite UART1 pin inserted in SimpleRTK2B UART2 Xbee socket?
SimpleRTK2B is MovingBase or Rover
Filename: “srtk2b+heading_lite_movingbase_FW_HPG112.txt”=> write to SimpleRTK2B or SimpleRTK2lite?
2:Rover of a simpleRTK2B+heading kit
Is SimpleRTK2lite Rover?
Filename: “srtk2b+heading_rover_F9P_FW_HPG112.txt”=>write to SimpleRTK2lite? or SimpleRTK2B?
Thanks , I tryed many times,to config to refer your pages https://www.ardusimple.com/configuration-files/ and https://www.ardusimple.com/simplertk2heading-hookup-guide/
simpleRTK2Blite：srtk2b + heading_lite_movingbase_FW_HPG112.txt
simleRTK2B：srtk2b + heading_rover_F9P_FW_HPG112.txt
writing finished, I was confirmed through Advanced Configuration>cfg-MSGOUT , 0X1 mark checked ,then writing is OK.
I watch Ucenter NAV>RELPOSNED through SimpleRTK2B USB ,but RELPOSNED not work,
SimpleRTK2lite is NO RTK and SimpleRTK2B is NO RTK too.
Antena distance is about 80cm .
Alone SimpleRTK2lite NTRIP measurement is good,FIXED 1cm within 2minute.
Please give an advice ,what wrong?
1. Are you loading the configuration files using our guide. You need to make sure you select “8/M8 configuration files”. Unfortunately we are still using the old protocol.
2. With which board are you sending NTRIP corrections?
Lastly, it would be very helpful to collect logfiles with following messages enabled: ubx-nav-pvt, ubx-nav-relposned, ubx-mon-comms, ubx-rxm-rtcm.
1, i was using generation9 ,then I chnage to M8/8 and writing the 2 config files.
2,Now NTRIP is not use,Moving base evaluaiton only ,so SimpleRTK2Blite not put on Xbee for NTRIP recieve.
Result is same as Yesterday,
Upper SimpleRTK2Blite LED=NO RTK Lighting/GPS FIX Flasing /RTCM IN Off
Below SimpleRTK2B LED=NO RTK Lighting/Xbee->GPS Flashing/GPS FIX Flashing/GPS->Xbee Off
Checking SimpleRTK2B through USB
NAV-RELPOSNED nabled=>No aciton only GPS ToW t counting
MON-COMMS enabled=> UART1(0x01)TX= 200byte/sec increasing ,USBTX(0x03)=400byte/sec increasing,UART2(0x12)TX=none,
=> UART1(0x01)RX=none,USB(0x03)RX=stop,UART2(0x12)RX=700byte/sec increasing,
BUT UART2(0x12) send sentences All zero Skipped byte 700byte/sec incresing
SimpleRTK2B can not undestand message to SimpleRTK2Blite ?
Is it possible master Configuration to Hand input?
Please give me your advices.
Very interesting. Now we see there is data going from simpleRTK2Blite to simpleRTK2B. Next check, can you enable on simpleRTK2B the message ubx-mon-msgpp , this will indicate which data is coming from simpleRTK2Blite.
