2.4 Bluetooth layer interfaces
Figure 3 illustrates the layers between the user applications and the 88W8987-based
Bluetooth module. The 88W8987-based wireless module requires a kernel driver loaded
on the i.MX 8M Quad host system and a firmware running on 88W8987 SoC. The combo
firmware gets loaded by Wi-Fi driver. The hci_uart driver provides the HCI interface
between the firmware and user application.
