IOIO Bluetooth and Windows 8 / 8.1

Notes on using the IOIO with Windows 8 over Bluetooth

This post describes the results of controlling various versions of the IOIO Firmware from Windows 8 over Bluetooth.  Initial content was extracted from http://joe.blog.freemansoft.com/2014/04/ioio-v1-dealing-with-firmware-versions.html and expanded with additional content.

I used the HelloIOIOConsole.jar  sample program to test connectivity between Windows 8 and an IOIO V1 running different Application firmware.  I also tested Mac OS/X Mavericks.

Using HelloIOIOConsole.jar on a Mac running Mavericks

My Macbook had no trouble pairing with the IOIO V1 with Bluetooth adapter. 4545 is the pairing code. The Bluetooth connection will go idle after some time and change from "Connected" to "Not Connected".  The IOIO serial device  ports on the Mac continue to exist even if the connection has gone to sleep. Bluetooth is re-connected when a program accesses the outbound serial device tied to the IOIO.  The Mac just worked.

Determining my Application Firmware Version using a Mac

I first tried HelloIOIOConsole, version 5, the latest, application java -jar HelloIOIOConsole.jar. That failed with the following output on my device.  Eureka!  It looks like I actually have Bootloader 303 and Firmware 323
App-IOIO0500.zip HelloIOIOConsole.jar[I/IncomingState] IOIO Connection established. Hardware ID: SPRK0016 Bootloader ID: IOIO0303 Firmware ID: IOIO0323[V/IOIOImpl] Querying for required interface ID[E/IOIOImpl] Required interface ID is not supported[E/IOIOBaseApplicationHelper] Incompatible IOIO firmwareioio.lib.api.exception.IncompatibilityException: IOIO firmware does not support required firmware: IOIO0005
Then I tried HelloIOIOConsole application version 4 java -jar HelloIOIOConsole.jar. Still no love with this combination.
App-IOIO0400.zip HelloIOIOConsole.jar[I/IncomingState] IOIO Connection established. Hardware ID: SPRK0016 Bootloader ID: IOIO0303 Firmware ID: IOIO0323[V/IOIOImpl] Querying for required interface ID[E/IOIOImpl] Required interface ID is not supported[E/IOIOBaseApplicationHelper] Incompatible IOIO firmwareioio.lib.api.exception.IncompatibilityException: IOIO firmware does not support required firmware: IOIO0004
Finally, I ran HelloIOIOConsole application version  java -jar HelloIOIOConsole.jar. The program ran fine and was able to manipulate the Bluetooth attached device..
App-IOIO0330.zip HelloIOIOConsole.jar[I/IncomingState] IOIO Connection established. Hardware ID: SPRK0016 Bootloader ID: IOIO0303 Firmware ID: IOIO0323[V/IOIOImpl] Querying for required interface ID[V/IOIOImpl] Required interface ID is supported[I/IOIOImpl] IOIO connection established
This means I am running version 3.x (!)


Using HelloIOIOConsole with Windows 8 with Firmware 3.03/3.23

I was unable to run any version of HelloIOIOConsole on Windows 8 with my IOIO V1 running firmware 3.23. None of them ever got far enough to verify a version match between the app and the firmware.

The PC and IOIO pair over Bluetooth without any issues.  Virtual COM ports are created.

The IOIO bluetooth connection status never changes from "Not Connected" to "Connected" even after letting HelloIOIO run for a while. Windows 8 told me that there was a driver failure every time a COM port was (re)opened.

I tried several versions of HellloIOIOConsole. The image at right shows up every time the console app runs and connects to a serial port. This message pops up several times.  Tapping on it takes you to the Bluetooth management screen which then tells you:
Adding your device didn't work. First remove it from your PC, and then try again.
The windows event log shows the following.
The mutual authentication between the local Bluetooth adapter and a device with Bluetooth adapter address (00:15:83:44:b9:e7) failed.
It feels like some kind of driver / protocol problem I don't understand.  This is fixed with later versions of the Application Firmware


Using HelloIOIOConsole with Windows 8 with Firmware 3.11/4.00

The PC and IOIO pair over Bluetooth without any issues. Here is the success matrix for HelloIOIOConsole.jar:

  1. PC Application version 3.23 works great. It logs the IOIO hardware and firmware versions and accepts commands.
  2. PC Application version 4.00 hangs "waiting for handshake".
  3. PC Application version 5.03 connects and logs the IOIO hardware and firmware version and and correctly terminates because the app uses a later IOIOlib than allowed for the 4.00 firmware

Fixing PC IOIOLib 4.00 to work with Windows 8


SerialPortIOIOConnection.java in IOIOLibPC requres that three lines of code be commented out.  You can find the source file at:
App-IOIO0400\IOIOLib\target\pc\src\ioio\lib\pc\SerialPortIOIOConnection.java
 Comment out lines 73-75

Conclusion

OS/X and Linux are more forgiving when working with Bluetooth and IOIO

Installing the RNDIS driver on Windows 11 to use USB Raspberry Pi as network attached

Image
I do a lot of my development and configuration via ssh into my Raspberry Pi Zero over the RNDIS connection. Some models of the Raspberry PIs can be configured with  gadget drivers  that let the Raspberry pi emulate different devices when plugged into computers via USB. My favorite gadget  is the network profile that makes a Raspberry Pi look like an RNDIS-attached network device.  All types of network services travel over an RNDIS device without knowing it is a USB hardware connection. A Raspberry Pi shows up as a Remote NDIS (RNDIS) device when you plug the Pi into a PC or Mac via a USB cable. The gadget  in the Windows Device Manager picture shows this RNDIS Gadget connectivity between a Windows machine and a Raspberry Pi. The Problem Windows 11 and Windows 10 no longer auto-installs the RNDIS driver that makes magic happen. Windows recognizes that the Raspberry Pi is some type of generic USB COM device. Manually running W indows Update  or  Upd...

Understanding your WSL2 RAM and swap - Changing the default 50%-25%

Image
The Windows Subsystem for Linux operates as a virtual machine that can dynamically grow the amount of RAM to a maximum set at startup time.  Microsoft sets a default maximum RAM available to 50% of the physical memory and a swap-space that is 1/4 of the maximum WSL RAM.  You can scale those numbers up or down to allocate more or less RAM to the Linux instance. The first drawing shows the default WSL memory and swap space sizing. The images below show a developer machine that is running a dev environment in WSL2 and Docker Desktop.  Docker Desktop has two of its own WSL modules that need to be accounted for.  You can see that the memory would actually be oversubscribed, 3 x 50% if every VM used its maximum memory.  The actual amount of memory used is significantly smaller allowing every piece to fit.

Almost PaaS Document Parsing with Tika and AWS Elastic Beanstalk

Image
The Apache Tika project provides a  library capable of parsing and extracting data and meta data from over 1000 file types.  Tika is available as a single jar file that can be included inside applications or as a deployable jar file that runs Tika as a standalone service. This blog describes deploying the Tika jar as an auto-scale service in Amazon AWS Elastic Beanstalk.  I selected Elastic Beanstalk because it supports jar based deployments without any real Infrastructure configuration. Elastic Beanstalk auto-scale should take care of scaling up and down for for the number of requests you get. Tika parses documents and extracts their text completely in memory. Tika was deployed for this blog using EC2 t2.micro instances available in the AWS free tier. t2.micro VMs are 1GB which means that you are restricted in document complexity and size. You would size your instances appropriately for your largest documents.   Preconditions An AWS account. AWS ac...
