Getting Started with NXP-based Wireless Modules on i.MX 8M Quad EVK Running Android 10 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.
