This project is for Kinets L MCU Brazil challenge.Actually we don´t know if the project was registered. The goal of this project is to make Bluetooth communication between an android and  Freescale Freedom development kit FRDM-KL25Z. We will show the FRDM-KL25Z accelerometer status and the internal temperature sensor on android app. The android app requires version 4.x or above. Bluetooth module is connected to UART1.The embeddec code was created on CodeWarrior and exported to Keil MDK ARM.   http://youtu.be/-waEkfIuZCw

This patch fix the issue in hdmi dongle JB4.2.2_1.1.0-GA release that wifi((STA+P2P)/AP) cann't be enabled properly. In the root directory of Android Source Code, use the following command to apply the patch: $ git apply hdmi_dongle_wifi_jb4.2.2_1.1.0.patch

Development environment Hardware: i.MX6Q SabreSD connecting rtl8188cus or rtl8192cus wifi dongle Software: FSL JB 4.2.2-1.1.0-GA release   Advantage brought by JB4.2.2 As we may know that in JB4.0.x, Wifi-Direct is exclusive to normal Wifi access AP, so means that you have to turn off  Wifi normal AP access, then turn on Wifi-Direct. But in JB4.2.x, it can support the following topologies in use scene as following: So that means you can keep p2p connection meanwhile access internet throught AP.     Feature verified 1. Wifi connection support internet surf, and DLNA. 2. Wifi-Direct can support files transmission like Gallery sharing based on Wifi-Direct Demo.apk from FSL. 3. Particial support Wifi-Display, but due to unavailability of Wifi-Display sink module, so cannot be verified fully.   Usage: untar the attached file, then "patch -p1 <" in corresponding subdirectories. It would be better to untar the file in an empty directory, so you can understand which subdirectories are newly created (ex. hardware/realtek is newly created), then within these newly created subdirectoies, you need to "git init" first, then do "patch -p1<" to adopt all newly added files and subdirectories. Original Attachment has been moved to: WiFiDirectDemo.apk.zip Original Attachment has been moved to: patch4rtl8188_8192_on_jb4_2_2-ga.tar.gz

There are two patches for HDMI Dongle JB4.2, one is remove the warning message, the other is fix to that sleep will not recover. Jack Mao

Warning to solder SMA connector:  please insure the PCB edge is well cut and right smooth; if not please mill a bit with a sand paper. (risk is to get SMA core line not well soldered on PCB line) KW47 from KW45 hardware porting :  KW47 is pin to pin compatible with KW45. However from HW point of view, some components values will have to be adjusted like RF matching components values. Other components around KW4x are not foreseen as to change based on current silicon validation.  Please also note some new muxing is in place to get new features of KW47 on pins. For instance on KW47 a second Flex CAN is available.
