As you might have noticed, one version of our Nitrogen6X takes advantage of the Murata LBEH5DU1BW WiFi/BT combo module.
This module is now supported in our latest Android 5.0.0 (Lollipop) release!
For the impatient
You can download the Nit6Q_W_BCOM image from here:
As usual, you’ll need to register on our site and agree to the EULA because it contains Freescale content. The image is a 4GB SD card image that can be restored using zcat and dd under Linux or Alex Page’s USB Image Tool under Windows.
Feature-wise, the support is the same between the modules:
- WiFi STA mode
- WiFi Ad-Hoc mode (hotspot)
- WiFi P2P (WiFi Direct)
- Bluetooth 4.0
- just like the TiWi, BLE peripheral mode isn’t supported
To be noted that WiFi Direct doesn’t interfere with Bluetooth at all, allowing users to use both features seamlessly.
Both tests have been running with the same iperf3 v3.0.10 binary with the exact same network configuration.

Source code access
Please follow our latest release instructions to retrieve the source code. Once everything is set up properly, you just need to modify one configuration file in order to specify the use of the Murata module (TiWi BLE being the default configuration).
