We are stuck trying to bring up WiFi & Bluetooth on i.MX 8QuadXPlus MEK running Android 11. So request NXP/Murata community members to provide your valuable feedback/support here.
Our HW/SW setup:
To start with, we checked out, built and flashed Automotive Android 11 (android_automotive-11.0.0_2.3.0) on our i.MX 8QuadXPlus MEK hardware. It is working fine straight out of the box.
Automotive Android 11 Release: https://www.nxp.com/webapp/Download?colCode=11.0.0_2.3.0_AUTO_SOURCE&appType=license
The below debug logs are seen (without any WiFi/BT module inserted yet):
[ 2.128114] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[ 2.138166] cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'
[ 37.140667] wlan: Loading MWLAN driver
[ 37.145806] wlan: Driver loaded successfully
Our WiFi/BT setup & trials:
We installed Murata LBEE5CJ1XK WiFi/BT module (from Embedded Artists) onto the M.2 connector.
WiFi/BT Installation Guide: https://www.embeddedartists.com/wp-content/uploads/2020/10/Getting-Started-with-M2-modules-and-iMX6_...
The setup document is for Linux, so the only relevant portion was about hardware installation, and it was followed as is.
There is no setup instructions available for Android, and we couldn't find any related kernel/driver patches either.
Android/kernel is not detecting the driver for the WiFi/BT module. There was no relevant changes w.r.t. serial logs, when comparing boot up logs with & without WiFi/BT module.
We found an old Android 7 based document (from Embedded Artist), where several kernel/driver patches were available for this chipset. However those do not apply on Android 11.

Kindly point us to the latest Android 11 based setup documentation for WiFi/BT module and the relevant kernel/driver patches to be applied.
Summary:
To summarise, these are our specific queries/requests:
- Does the i.MX 8QuadXPlus MEK running Android 11 support Murata LBEE5CJ1XK WiFi/BT module?
- If yes, kindly share the setup documentation and relevant patches.
- If no, kindly guide us on which M.2 WiFi/BT module to be used (along with relevant documentation).
