Hi!
The cache is used to store the TOC (Table of Contents) of log variables and parameters.
The TOC is downloaded as a part of the connection sequence and this takes a couple of seconds. If you specify a path when creating the Crazyflie object
Code: Select all
Crazyflie(rw_cache='./path/to/my/cache')
the TOC will be saved to file. The next time you connect, the TOC will be loaded from file instead and reducing connection time.
