REALTEK DRIVER

This driver supports loading firmware images and optional config data to USB dongles with a Realtek chipset. A number of USB dongles are supported, but likely not all. When using a USB dongle, the USB product ID and manufacturer ID are used to find whether a matching set of firmware image and config data is needed for that specific model. If a match exists, the driver will try load the firmware image and, if needed, config data. The driver will look for those files by name, in order, in:

• The directory specified by the environment variable BUMBLE_RTK_FIRMWARE_DIR if set.
• The directory <package-dir>/drivers/rtk_fw where <package-dir> is the directory where the bumble package is installed.
• The current directory.
