Greetings, We are currently developing a BLE based proximity tracking device which connects to an Android app and helps user track/find their belongings. It is similar to a Tile or TrackR tracking device but with higher working range and some unique features to enhance user experience. We are using a TI chipset of CC2541 with extender and on-board antenna developed by RadioLand China (Model CC2541PA1). Our board design is done with a firmware in place and an Android app that talks to the device. We have two issues with the app that points to issues in our firmware + app that we need help fixing. These two issues are: - Proximity compass: Use the RSSI, BMA 250 sensor and algorithms to guide the user to the lost item where the tracker is placed. This feature guides the user to the tracker like a compass (left or right, straight or back etc....like directionally more than regular bluetooth tracking of just notifying radius between devices. - The distance calculator between the tracker and app/phone needs to be optimized for accuracy - There should be multiple devices that a user can track so they can put the trackers in multiple things around them We are currently in an urgency to fix the issues and finish the prototype for a demo. Once we demo the prototype, we will have to go into a turning the rigid PCB to a flexible PCB with onboard battery and do production work. So the project will contain a lot of PCB design, firmware design and app work before releasing it in the market. Right now, i am just interested in finishing the prototype for our stakeholders before moving to the next stage. I request interested parties to have prior experience in the exact same application or close thereof so we can start troubleshooting quickly. Also interested candidates should be prompt in response and providing feedback. We have several prototypes that we can test but the software development in the interest of time will have to be remote. We can consider shipping a device to you if that accelerates the process.

Upworker to do the ffg; 1. Design a circuit with the utilisng the PS25251 sensor (refer to http://www.plesseysemiconductors.com/doc/?id=291766) 2. The sensor should be mounted on specially designed circuit board (with the same footprint of the sensor) 3. The circuit board should have a connector to which a harness connects to. 4. The circuit board connects to another 'motherboard' which has an LCD and MCU 6. Upworker should source a single PS25251 sensor from suitable local supplier (~$10). 7. Circuit to be designed using equivalent components from www.mantech.co.za 8. Upworker should not buy any additional components (other than the PS25251) 9. Supply voltage is 12VDC (should be regulated to supply sensors + MCU) 10. MCU should be a PIC (5V or lower because sensor operates within this voltage) Deliverables 1. Simulation 2. Through hole PCB design (single sided) for the motherboard (Gerber files required) 3. SMD PCB design (double sided) for the daughterboard (Gerber files required). This side should not have the connector as it is the receptor 4. Video of the working circuit 5. Code in C and instructions on how to program using PICKIT 3.

My (cut down) Arduino seems to restart under heavy load - as in lighting an LED strip consuming 1~2 amps. It works fine with lower loads. I need an expert to look at it and advise me what could be wrong? No time wasters needed! If you have the skills and worked on something similar before, then please send me the following: 1. Your mobile number with country code and all 2. Similar project you have worked on Work will only be considered complete when your proposed solution works.

We invite applications from experienced PCB designers to help us with our project. The project involves measuring the resistance of 5-8 sensors as an analog voltage signal and providing the signal via Bluetooth LE to any device. The resistance of the sensors may be anywhere between 20 ohms to 100 ohms. The entire circuit, including the battery, should fit in as small an area as possible (preferably within 2 inch by 2 inch). At the end of the project we expect you to deliver all the files necessary to get the PCB manufactured. Please begin your application with "abc123" so that I may know you have read the whole job description.
