I wonder who might offer a development kit for bluetooth including flash and interface for own circuits ? I need to build measurement gathering system with 2-3 pcs of clients gathering measurement of tachometer information and send it to one common host and further on to the screen. Host would be standard class 1 BT usb dongle and visual basic application connected to the virtual com port. B...

Hi, I'm looking for a Bluetooth module for a low-volume product which needs basically a replacement for a serial protocol and for which the complete docs are readily available and which has enough of an sdk (again readily available) to get started in a bare metal system. My last experience of BT was that suppliers keep their cards very close to their chests as far as docs etc are

Hi folks: I have a task to convert a dozen or so audio files into SBC encoded files. SBC is Bluetooth's A2DP compression method. The product requirements state SBC encoded files will be used to conserve storage space. They are product voice prompt files. I've had no luck finding any sort of something-to-SBC encoder on Google. I'm hoping to get lucky locating an encoder from advi...

Hi, I'm trying to build a cheap digital audio link providing reasonable sound quality and working directly with the ALSA/jack-audio system in a Linux embedded system. I've stated that there are available relatively cheap Bluetooth modules supporting the A2DP. One example may be Rayson's BTM730: http://www.rayson.com/btm730.html Unfortunately, all I could find was the info, that it offers 1...

Is anyone using 16M (FIR) IrDA ? Looking over the history via the magic of Google, I see a burst of interest around the beginning of the current century, and not much recently excepting perhaps HP err.. Avago. I also don't see much in the way of available (OTS) hardware.. Has Bluetooth rendered it comatose? Is there a non-RF alternative? Or is it just coming up to speed? Best...

I am looking at developing an industrial product which will have BT. Obviously there are numerous ways to do it, with any microcontroller and one of the BT modules. My preference is towards the Atmel ATmega128 because we have some other projects, currently using a Hitachi H8/323, which will eventually be migrated to that. Atmel, along with Microchip, seems to be the only company committe...

I've been gearing up to take on a new hobby project, building a wireless MIDI controller. I've done a fair bit of research and I am pretty straight on what parts I need for the task and so on. The one roadblock I've hit is making the setup wireless. The options I've explored are mainly Bluetooth and RF with the latter looking to be more promising. Problem is, I'm so new to this t...

Hi all, I'm new to this forum - hope to find some answers/help on the following: I doing a project in which a laptop needs to communicate with a remote PIC-based device. I had originally planned to use RS232 at each end talking through a pair of 900 MHz Linx transceivers. Since this was to be a one-off prototype, I kind of ignored the regulatory issues. Now, I'm thinking that maybe I...

I'm in a group designing a 3d positioning system for a foot for a class project this semester. We're looking to base our device on some analog devices accelerometers, and hopefully incorporate Bluetooth support (but we may well just use USB to get the data off). The accelerometers have 2-axs PWM output and we'll be using four; does anyone know of any low cost chips with lots of counters, fo...
