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
