   Hi, I have similar problem on parsing and logging as BLF. also, some option interface is needed for selecting channel among recorded data when more than one channel data is logged into one BLF file.

   There is a similar issue #786 for which there was a pull request made but was probably abandoned. I created a new which I tested with your attached log and had no issues. You can try it out yourself:
