[Feature Request] : script to repair UBX files

[Eric-FR]

Sometime, the Sparkfun Express is producing slightly corrupted files : https://github.com/sparkfun/SparkFun_RTK_Firmware/issues/49

Similar to the UBX_Integrity_Checker script, I would appreciate a script that can repair damaged files i.e. that remove incorrect sentences.

Hi Eric (@Eric-FR ),

We should be able to adapt the UBX_Integrity_Checker so it can 'snip out' bad sentences. Would that meet your needs? (Is Python code OK for you?)

Best wishes,
Paul

Yes, of course, it can be done with Python. I did a try on your Checker two days and it was successful. It confirmed me that there was some corrupted sentences ;-).

Hi Eric (@Eric-FR ),

Please try this version of the integrity checker. Please let me know if it repairs your files correctly. If it works for you, I will merge it into the main branch of the library.

Very best wishes,
Paul

I successfully tried. First file made with Express v1.8 firmware with 1 error. Second file made with an older version of firmware with 57 errors.

After repair, the integrity checker didn't detected error.
I also checked with Stefal ubx_converter. Both scripts agree on the number of errors before repair. After repair, the converter didn't detected any error.
I was able to open the repair files in RTKPLOT and RTKCONV parts of RTKLIB (although uncorrected files are also opened without problem).

So, I think, that's all right.

Thank you @Eric-FR ,

I am releasing the new integrity checker in v2.0.16 of the library. Thanks again for the suggestion!

Best wishes,
Paul
