Android /Java application using the IOIO Java library for communicating with hardware using an SPI bus -- 2

I need to modify some existing code, which is an android application to control a BLUETOOTH ULTRASONIC DEVICE by US SMART probe scanner.

The main task is to interface with the probe interface. SPI is the communication interface for the hardware -that's what you use to talk to the probe Bluetooth unit and use to pull data off.

We need and android/Java expert who's familiar with or has experience with using the IOIO Java library for communicating with hardware using an SPI bus - someone with microcontroller knowledge should have the skills.

The app can connect and send requests just not receiving any meaningful data and I need someone to resolve this issue.

Info on Scanner.

BLUETOOTH ULTRASONIC DEVICE : US SMART

The US-SMART is a unique worldwide device due to the BLUETOOTH connectivity and its ANDROID environment. This ultrasonic device is powered supply via battery Li-Ion.

We provide the US SMART with a smartdevice and also the application to control it.

On ANDROID systems – wireless – Bluetooth connection between the US SMART & the tablet or smartphone

Tactile tablet or Smartphone (ANDROID OS)

U S - S m a r t

The US-Smart allows a ultrasonic wireless control using the bluetooth between the couple probe / US Smart and your tablet or smartphone.

By using the US-Smart, you’ll have the possibility to make statements of measures until 8 m of the US Smart.

This device can also allows to realize various kinds of inspections such as welds, rails inspections, composite materials…

Features General Description

The US-Smart is a unique worldwide device due to the BLUETOOTH connectivity and its ANDROID environment.

This ultrasonic device is powered supply via battery Li-Ion.

His main quality is its small size and its ‘ready to use’ concept.

The US-Smart has been created to simplify the NDT controls.

The transmitter can generate pulses with a voltage level and a width programmed by the user. A low noise preamplifier combined to a VGA gives a gain range between 0 and 80 dB, a DAC curve is also available. A 12 bits analog digital converter with a sampling frequency of 80 MHz is used to digitize ultrasound signals.

The device has 2 working modes : Transmission or Reflection.

•  Bluetooth

•  Android System

•  Battery Li-Ion (capacity : 2 600 mAh)

•  Battery life : 8 hours

•  Available connectivity up to 8 m

•  Ultralow noise preamplifier : 0.74 nV/√Hz

•  - 6 dB bandwidth : 540 KHz to 18 MHz

•  High voltage transmitting pulses

•  50 Ω load drive

•  Digitizer 12 bits at 80 MSPS

•  Programmable gain : 0 to 80 dB

•  DAC curve

•

• Applications

•  NDT

•  Trainings

•  Teaching

•  Android environment

• US SMART IS PROVIDED WITH A SMART DEVICE
