Hello,
now this may seem like a silly question, but I have been trying to do some
simple shell scripting with hcitool's LE scan and redirected its out and err
streams. The result is not quite what I am expecting:
hcitool lescan --duplicates > /tmp/lescan.out
This will create the output file immediately, but it remains empty until the
hcitool process terminates. Only then does the entire output get flushed. Any
idea why the output does not get written immediately? Ie. why I can't "tail -f
/tmp/lescan.out"?
My intention was to pipe the output through a shell script to add a timestamp to
each line, so I get a simple log during testing. I did not want to modify
hcitool/write my own C program just for this purpose.
Kind regards,
Edmund
