Correction! It appears the "NTRIP" mode configured in firmware does not really work through the Ethernet, the "RED" led only lights up in "OpenArc Client" mode. So there appears to be a bug that makes the NTRIP mode only work through Python Driver, while Openarc client works through the Ethernet without Python Driver. Please fix the bug so NTRIP can also work through the Ethernet without Python driver running.

that's just an default NTRIP setting, and ntrip server user should use local service or server.

@zhihengcao said in Where is openrtk_data_parse?:

I am reading https://www.eye4software.com/hydromagic/documentation/articles-and-howtos/ppk-surveys/ Can you support this flow to allow OpenRTK to be used this way?

yes, that's what OpenRTK330LI designed for, we open-sourced peripheral FW for user to customize, please refer to Aceinna(PlatformIO) extension on VSCode, and import project from there

@zhihengcao said in OpenRTK INS Status INACTIVE / INVALID?:

Thanks. Do I need the Python driver running on a PC always in order for RTK to work?
Can I plug in the Ethernet to a travel router with Internet access and not connect the USB/UART & Python driver, but still have the system logging data? Or must I take a laptop with the Python running when carrying it on a test vehicle/aircraft?
I think since there is onboard M4 ARM processor, you could write firmware to connect to NTRIP through the Ethernet and log data. Where can I find any example firmware with source code?

With the EVK, you need a "storage" for the data logging, right? no matter UAR/Ethernet connection. I guess you mean logging data through ethernet and pull data from ntrip server over internet, but where the logged data saving to? on your platform?

@zhihengcao said in Where is openrtk_data_parse?:

When Internet is not available during data logging, can past RTK Base RTCM data (rtcm_base_xxxx.bin) be downloaded from somewhere?

no, unless you're receiving RTCM data from base station via radio other than internet, the logging tool just log what the module receives from the base station

@zhihengcao we need driving/motion testing to have INS working. INS initializaiton requires few seconds of straight motion with speed > 4 m/s.

hi ethan, could you please share your openRTK330LI device ID? have you played with the device with ST-LINK already (in this way, it could cause FW image damage)? and from the python driver console output, it seems it did not found the device from PC.

@Minho-Lee Appreciate the interest, we just release the customizable FW on Github: Aceinna/openRTK330-lib, together with the platform on Github: platform_aceinna-imu, you will have a GNSS/ins library wrapped with open-source FW. The RTK_INS App on the platform is available in a day or two for you to import from the VS code. Then, you could modify the UART, CAN, SPI and Ethernet interfaces and debug with OpenRTK330LI module.

Please email to dwang@aceinna.com for later quick response. Thanks.

currently we do not support NMEA/ASCII attitude, but you could decode our binary format to get that info, and the decoder in Python is open sourced in https://github.com/Aceinna/python-openimu

OpenRTK330LI is a GPS/IMU integrated system, with Inertial measurements, it reflects the heading in 100 Hz real time.
