We are developing an audio remote control for car/boat stereos that is unique to the industry. We will share more details upon hire. What you need to know: We have learned that we need a particular Bluetooth chip that meets the requirements of range (approx. 100 feet) and battery life (ideal goal is to have disposable common battery that lasts 3+ months, rechargeable if we must). Also, this chip is unique in that it can connect to both a smartphone or directly to the stereo receiver (AVRCP mode). This is important to have both options because some consumers don't have a smartphone and wish to link directly with the stereo. I am in need of someone to program the chip. The chip is the WT32i by Bluegiga; I have this development kit for it [url removed, login to view]
The tasks are to program the chip so that it can link up with the stereo receivers (AVRCP mode) and control the basic audio commands of Play, Pause, Skip forward, Skip backward, Volume up, Volume down. Additionally, I would like a button that will scroll through the various Playlists, if any. This Playlist function would be used when an MP3 player such as an ipod/iphone was the source of music play (since these devices use Playlists), whether connected via smartphone or via stereo receiver. Another button would be an Activation button that would need to be held down to activate the other buttons. This prevents the buttons from being inadvertently pressed or pressed by the force against the water when the rider falls and lets go of the handle. The same tasks are required for linking up the chip with a smartphone. Preferably, it would link with the native audio player on ios, android, and windows smartphones. Alternatively, we would create a simple media player app top connect with. Also, thinking about whether it would work with apps such as Pandora (it would likely work if connected via stereo receiver, but would it work if connected via smartphone?). Finally, in both scenarios, we need a switch or combination of button pressing to determine connection route (i.e. hold down play button and skip forward button for 5 seconds to connect via stereo receiver, …and skip backward button to connect via smartphone).
We have a PCB board developed, but will hold off on ordering it until the chip is programmed since we may find some things to tweak in the process. For example, I think we need to tweak it to have a switch or combination of button pressing to determine connection route (i.e. hold down play button and skip forward button for 5 seconds to connect via stereo receiver, …and skip backward button to connect via smartphone). Pardon my ignorance, but I don’t know whether this is implemented into the PCB board, the chip, or both.
We also need to look at the current battery set up and see if it suits classic Bluetooth well for power consumption or if we need to switch batteries or go with rechargeable.
Rechargeable might not be so bad if we must since we should implement a mini USB for updating the device anyway. You would need to program the bluetooth chip and/or PCB board to implement mini USB.
THE DEADLINE IS 4/22/14. This gives us 6 days to get the PCB board ordered and delivered and 6 days to put it all together for the design show on 5/6/14. Even if our deadline cannot be met by a given referral, I am still interested in the referral. Perhaps I can make some adjustments to the schedule and still make it work. At a minimum, we could get the AVRCP mode accomplished first by and then the smartphone mode second. Thank you for taking the time to read this and possibly refer me to someone who could handle this project (or hopefully you can do it!).
