What is the baud rate of the data connection between base and rover Alpha?
I am trying to get radio modems between them for it. Can it be adjustable like 9600 or 33600 for many std device? For use with Lora slower but more secure link, gsm phones etc.
What are the hardware specifications. Especially modem-rover data connection. 3.3V TTL serial data, max 3.3V in/out ? 115200 baud 8 N 1?
5V ok? other? Any manual?
Is the hardware directly a chip like https://www.skytraq.com.tw/homesite/S1216F8-RTK_v2.pdf
And messages etc. are from it?
in my rtkviewer 220.127.116.11 version update tells it can not find update server to update rtkviewer.
I updated it manually from a link here, which is ok for me. ( polaris-gnss.com/rtkviewer.zip 1 or something)
( I tested even via VPN to be in Taiwan, all firewall was down etc. Can I try it otherway like ftp, ping it if I know the address…)?
I could not get firmware check by rtkviewer.exe by going into 9600 speed. It just wont connect then. (win 10 PC) I don’t need it yet. I tried to check if I has latest firmware. I am doing R&D to get this RTK going here.
-I am now buying now rf-link for base-rover Alpha data ports. Takes some time to find operational pair.
I don’t now its baud speed? Has anyone any idea?
( Problems to find flexible and good small standalone 868MHZ Lora or standard device and meet the regulations ) 868 and 434 are used for car keys here with 10mW and 1W could block 1 km radius.
I can not find any instructions to use polaris-gnss.com server for NTRIP server. Or if it is available with fixed ip?
I found an blog of floating server but I did not study it, yet.
-I hope I do not need PC as a NTRIP server but only data link bw base and rover stations.
I hope to build an permanent 1-2 km base station with a battery + solar cells on the field where there are 30 m ‘hills’ in the way. to start with.
-Do you have an idea what is the source of EMI disturbing antenna? Alpha, wires, Power pack? I could build some emi shielding then, metal mesh or lates, ferrites, emi capacitor to power wires etc. My intention is to build up a standalone base station and rover. With antenna.
