We are hiring a developer/engineer to create only the beginning of an application. If this milestone is completed well, there will be more work immediately. The requirements are as follows: This deliverable involves two devices 1) 1 Smartphone 2) 1 Bluetooth Low Energy Chip (Texas Instruments SENSOR - CC2541) or similar chip. Coding Involved: 1) App development (Samsung Galaxy S4 or iPhone 5). 2) Programming firmware of Bluetooth LE chip to execute sound Alert when proximity rule has been broken. Requirements: 1) Pair two Bluetooth devices upon entering a certain proximity of each other. (Bluetooth LE chip to phone) (Master/slave configuration in that order) 2) Once paired, Set Alert level to High Alert (sound) on Slave (i.e. phone) if pairing is broken [PROXIMITY PROFILE] 3) If alert level not deactivated AND proximity exceeds a preset value then sound alert on secondary and phone AND send txt to predefined contacts with message and the following data (gps loc, temperature) 4) Disable Alert when user selects this option from app or physically presses button on chip to disconnect 5) Enable Alert when new pairing connection is made (i.e. Bluetooth Chip connects with phone. 6) Knowledge of Generic Access Profile (GAP) and Generic Attribute Profile (GATT) required 7) Knowledge of writing firmware/code specific to Bluetooth LE chip technology is required 8) Knowledge of mobile application development required For completion of this project, please have the app software up and running on a development web server it can accessed to test its functionality as described. Also please provide the equivalent hex/firmware file containing the code used to program the Bluetooth LE (Texas Instruments SENSOR - CC2541) chip as described. VERY IMPORTANT: To separate you from the spammers, please write "CONDI LOGIC" as the first line of your bid. We will delete all bids that do not start with this phrase, since most bidders never read the requirements. Thank you for being one who does. Regards, Conditional Logic Ltd.

CONDI LOGIC Hi there, I have worked on a few bluetooth iOS projects before, both classic and LE. Devices from ConnectBlue OBS414 to some bluetooth printer. Most of your requirement are doable, except sending gps to contact. What I understand is that TI CC2541 doesn't have GPS info, only has temperature and gas data. One workaround is sending gps of phone location. not from chip. My bid is for iOS only. Regards, Frank

CONDI LOGIC Dear Sir, Since I read your requirements I would kindly ask you to check my portfolio and completion rate on this portal. If you initiate private messaging I can send you few images and videos. It will show you project that I've just finished using CC2541. I've made custom hardware, custom firmware (client proprietary profile) and simple iOS application to test all the features. I have CC2540 development kit with me and all necessary Apple equipment to finish the project. If you have any questions, please don't hesitate to ask. Best regards, Darko.

"CONDI LOGIC" G'Day from Australia, Please initiate a PM. as I would like to bid on the H/W design phase, and work with whomever you select to do the firmware/app, or I have my own ppl available to do the firmware adn app as well. I have recently finished 2 seperate B/T LE4 designs, each with different chipsets (CSR & Nordic), but quite look forward to developing with the TI chipset. I design for mass production in mind, and use Altium, as well intergrate SolidWorks (as I work closely with some great industrial engineers as well) into the design cycle so you can see exactly what you get as a completed product. my current bid is just a palceholder, as my normal rates are traditionally $75/hr, but would bid at $60/hr to be involved in your project... :) Cheers, ScoutMaster
