    The Sketch needs to scan for specific BLE devices and then display a signal strength via a coloured 5 led bargraph, play a beep, and show accumulated points for the time spend within the vicinity of a found BLE device. Required deliverable for this project will be a single Arduino Sketch. This project is a follow on to a previously completed Bluetooth BLE Scanner MIT Inventor App (see project brief attached). The APK can be found in the project files on Freelancer. The objective of the MIT Inventor app was to prove that the BLE scanner concept would work. This follow-on project will to be to extend the concept to an Arduino Nano Microcontroller. See attached PDF for full project description

    Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

There has been a new pcb built with the 675 but with many of the same components as found on the Starter Kit. The new board has some pin changes from the Starter Kit. As much as possible has been kept the same. The new board does have more capabilities than the old Starter Kit.

    This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

    Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
