Hi everyone.
We are ESPrtk team.
Right now you can create yourself an NTRIP CASTER server with only ESP32 here.
Hope it will help your work.
Hi I am new to all this so still getting my head around things. I am looking to have an rtk base station using ntrip. I currently have a arduisimple rtk2b board and antenna so am I correct in thinking I need another rtk2b board and antenna for the base station? Do I need the WiFi ntrip master to plug onto the base station board to connect it to the internet? Thanks
Yes, you need another rtk2b board and antenna for the base station and yes you need the WIFI xbee pluged in to the base station board, alternative would be to buy a esp32 for a dolar or two and use that instead of the WIFI xbee. Its simple to connect and flash the firmware to the esp32 and you save a lot of money.

Hi, could you please explain to me how to use source code xbee and create flash files? What is the program to use? I want to change the outputs.
Hi, this link contains a zip file with everything you need to flash the ESP32. Everything here is from this forum from people that helped me, hope you find it usefull. If you dont understand something, just ask.

Ethernet connection is stable than WIFI.
You need to ensure you have a decent radio signal. If you have any dead spots, then RTK corrections will fail until connectivity is restored.

Hello,
I tried firmwere 0.5.4 and 0.5.2 on ESP32 it installed successfully connected to wifi and activated NTRIP caster.
Tried ardusimple base config and Basis_Ortner.txt
simpleRTK2B_FW113_Base-00.txt
It works and connect, rover gets rtk fix but only for short time after that ESP32 crashes wifi hotspot disappears.
1005: Stationary RTK reference station ARP
1074: GPS MSM4
1084: GLONASS MSM4
1094: GALILEO MSM4
1230: GLONASS code-phase
Messages are allowed on UART2, baudrate is set to Xbee default 115200.
Until NTRIP client is connected ESP32 works no problem shows UART B/s that it’s communicating.
Anyone running ESP32 as caster and experienced similar issues ? or have config for NTRIP master as caster ?
