Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Linux OS
3.3 Bluetooth layer interfaces
Figure 7 illustrates the layers between the user applications and the NXP-based
Bluetooth module. The NXP-based wireless module requires a kernel driver loaded on
the i.MX 8M Quad host system and a firmware running on NXP SoC. The Wi-Fi driver
loads the combo firmware. The hci_uart driver provides the HCI interface between the
firmware and user application.
