BLF Parse error

[yolaalabi]

hello, I get a BLF parse error when opening a normal BLF file, is there some workaround? can I email the file to somebody to check out?

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.

Error see file below as zip

import can

file = r"C:\EbAT\blf files\Testing_w_FD"
log = can.BLFReader(file+'.blf')
for msg in log:
print(msg)

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:

pip install https://github.com/hardbyte/python-can/archive/bugfix/803-blf-parse-error.zip
