Hi,

Using the WYSAGVDXG Wifi-BT combo module with the chipset of NXP88W8887 in the Imx8qxp board.

We are testing the Bluetooth interface through the SDIO interface provided by the NXP. (SD-BT-CHAR-8887-U16-MMC-15.26.19.p38-C4X14113_A2-GPL-src.zip) and using the fwimage (SD-WLAN-SD-BT-8887-U16-MMC-W15.68.19.p38-15.26.19.p38-C4X15659_A2-MGPL.zip)

Follow the procedure based on the attached document of Android integration for NXP based modules (EMMY-W1, LILY-W1 and JODY-W2)
