I did it again and this time it worked. Very cool! It is about 5x slower than flashing with ST-LINK or VS Code though.

I followed the instruction on https://openrtk.readthedocs.io/en/latest/useOpenRTK/Go-Mobile.html
In the step
"Open the “OpenRTK” Andorid App, as shown by the picture below, go to the “Connect” tab and click the “search” icon (right bottom) to search for your device."
There phone does not find the EVK.
I tried flashing to the factory original firmware, it cannot be found. The android phone has Bluetooth turned on. I can find other previously used BT devices.
Thank you, I have been reading this example and it helps me understand the system a lot.
The RPK/INS correction is your proprietary and done inside a closed source library (.a file). This is totally fine, but the example firmware only demonstrates correction in real time assuming Base RTCM data stream from UART or BT or HTTP.
I am looking to implement Post Processing, the firmware stores the IMU and GNSS raw data into on-board memory, then receive archived Base RTCM data stored in the past, to run your proprietary library. Can you tell me if this is something that can be achieved with your proprietary library without limitations? Does your proprietary library have some restrictions, like it has to be run based on realtime/live data? Does it have restrictions it has to be run in combination with some hardware & firmware? In other words, do you limit your proprietary library to run only on the OpenRTK module, or can it be ported run on any ARM processor?
No RED LED:
NTRIP-CLIENT & CONNECTED
Red LED flashing:
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.
To answer my own question, the 220.127.116.11 along with username/password is specified in openrtk.json file of settings folder of the Python driver, and it works. The 18.104.22.168 along with another username/password is baked inside the firmware and does not work. So I put the info from openrtk.json via http://192.168.137.110/workCfg.shtml into the firmware, now I see the "RED" LED flash even without Python driver running, as long as the Ethernet cable is plugged into somewhere with Internet access.
I noticed that even when Ethernet is connected and has Internet access, the "RED" LED does not light up (indicating no data from NTRIP) unless I start also the Python driver.
Also, the Python driver reporting connecting to "22.214.171.124" regardless of the setting I put in http://192.168.137.110/openarcclientcfg.cgi "Work Config", If I put NTRIP Client mode IP=126.96.36.199 or OpenARC client IP=openarc.aceinna.com (188.8.131.52) the Python driver still connects to 184.108.40.206. Where is this IP address 220.127.116.11 coming from? How can I change it to NTRIP server that is local to my position so the RTK will actually work in my location?
I plan to write the STM32 firmware that run inside your module, to connect via I2C or SPI to a SD card module to store data.
My application will not have reliable Internet connection during logging, so my goal is to store the "rtcm_rover_xxx.bin" data and IMU "user_xxx.bin" data in the SD card then when Internet becomes available, send these data to our server to perform PPK + INS using something like https://www.eye4software.com/hydromagic/documentation/articles-and-howtos/ppk-surveys/
Please let me know if OpenRTK can be used for this.
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?
