Custom message on bluetooth bracelet(repost)

The goal of this project is to display a custom message on the LED screen of a Bluetooth bracelet that was originally intended to display the phone number of incoming calls to a mobile phone. In this application, the message will come from a PC running linux (and not from a mobile phone). ## Deliverables ** Background: I would like to use an inexpensive Bluetooth bracelet as a simple text display for a linux box. The device sending the message is a linux PC running Ubuntu, with a USB bluetooth dongle. I will not be sending the developer a bracelet or dongle as part of this project. ** Goal: This project will be considered a success when I am able to run a shell script on my linux PC that uses my hardware to send a custom text message to the bluetooth bracelet. ** Proposed Deadline: If 7 days is not enough time, please let me know and we can negotiate a different schedule. ** Preferred methods: Ideally, the script will work with existing bluetooth utilities (such as bluez, rfcomm, hcitool) to make the connection and send the message. I prefer smaller programs with fewer dependencies, written in shell script or the C language. ** A bit of information about me: I am capable of writing computer code and will be able to test the scripts and code during development. However for this project I would like to get someone else to write the code so that I can work on some other projects instead of this one. I expect to have frequent communication with developers, and am ready to participate in discussing the technical issues and tradeoffs. I expect developers to be proactive in communication with me: I want to know what challenges come up, and I want to receive regular updates on progress. I recognize that surprises and extra difficulties can come up during the project, and I pledge to you that I will try to be flexible when that happens -- but I expect to be well informed about these difficulties and their effect on the target delivery date. I am ready to start the project right away. If a good candidate shows up soon and makes a bid, I will close the bidding and get started (not waiting for the original bid period to end). So please bid early! Technical details: BRACELET- The bracelet is for sale here: [login to view URL] and I have one in my possession. $ sudo hcitool info xx:xx:xx:xx:xx:xx Requesting information ...
