I connected U-Blox F9P module to OpenIMS300 (INS App) by following the wiring instruction in the document and above dated 5/15/2019. But the latitude and longitude are "0" (Note: I connected the F9P module to PC and used the U-center software provided by U-Blox, the latitude and longitude are not 0). What's is wrong?

@John-Xie , your question has been answered in another post. And, please don't ask the same question in different posts.
If that does not solve your problem, please feel free to ask here.

Yes. I knew it. But I followed the wiring instruction, it is still “0”.

Any hint?

Thank you.

Wiring is the first step. You need also to config the receiver protocol to output NMEA or NAV-PVT, and config OpenIMU300ZI to the protocol you configured.
If there is still no luck, you need to dive into the GPS driver in the source code to see why.

Dear Xiaoguang,

It is still “0”.

I just got U-Blox M8Q and will hook it up with OpenIMU300 to see what happens.

Dear Xiaoguang,

Using U-Blox M8Q, I got non-zer0 GPS data. See he results posted below

@John-Xie , The system seems working. However, if you are using an old version of the firmware, I would suggest you updte to the latest firmware via the Aceinna extension because there are many updates.

"I have an OpenIMU 330bi and a u-blox ZED-F9P (C0PP-F9P evaluation kit). The pins are connected, and I am plotting GPS data in Acceina Navigation Studio. What code do I need to modify? I need an urgent response. Please provide an answer."
