what is the correct way to setup simpleRTK3B (Mosaic-X5 Triple Band (L1/L2/L5) RTK GNSS module) with WiFi NTRIP Master using NTRIP correction data via a smartphone hotspot.
What I have tried so far (using the webinterfaces for 192.168.3.1 and 192.168.4.1):
- enabled smartphone hotspot and mobile data
- configured NTRIP Master to connect to my smartphone hotspot -> success
- configured NTRIP Master NTRIP client
- configured simpleRTK3B: GGA-NMEA output stream at COM2 port at 100 msec
- configured simpleRTK3B: corrections -> COM2 -> Input Streams -> auto or RTCMv3
NTRIP Master doesn’t seem to receive any correction data (RTCM3) via the configured NTRIP-client although NTRIP Master uses the smartphone hotspot. -> no correction data streams to simpleRTK3B.
- Is the connection to NTRIP caster successful? You can check that by setting a different LED color for this function (e.g. red). Or connect via serial terminal to POWER+XBEE at 115’200bps and you will see the text strings.
- Configure the Septentrio as input only “RTCM”. The text string from the WiFi are not liked by the “auto” mode of Septentrio.
- GGA at 10Hz is a bit too much for many casters, maybe they are kicking you out. Try with only 1 GGA every 1 second. If you need 10Hz in your application via WiFi, you can upgrade the WIFi to a beta firmware which filters this sending of messages to the server (v0.5.4 at https://github.com/nebkat/esp32-xbee/releases)
thank you for the quick response.
After I changed the input stream to RTCMv3 and NMEA out stream (GGA) to 1 second, the connection to the NTRIP caster was successfull.
The Septentrio also reaches a RTK fix but after about a minute it falls back to DGPS.
In the XBee webinterface is only a steady NTRIP client out data stream but no steady in data stream (most of the time: 0 B/s in).
Does this mean that RTCM3 corrections go to the Septentrio but the GGA stream is not continiously sent to the NTRIP caster?
I have connected SimpleRTK3B to the smartphone via USB serial and used SW Maps.
Is there a way to connect the Septentrio via the WiFi-XBee-Hotspot (192.168.4.1) to the smartphone and get GNSS data to use e.g. with PinPoint-GIS?
About your later question, if Pinpoint GIS supports TCP/UDP gps receivers, then yes it should be possible via the IP of the WiFi + configured port.
The connection lasts about 10 seconds and then breaks.
The same thing with different smartphone models.
The NTRIP correction works well with EMLID Reach RS2 (same parameter for NTRIP client; correction data also via smartphone hotspot and WiFi of Reach R2).
