Hello all, I have recently acquired a bluetooth development kit (TDK's blue2i + USB adaptor). I have successfully connected the serial ports and transferred and received the data at 9600 baud. I want to use the serial module in customized hardware. But the serial unit is very expensive (around 92 pounds). What alternative chips do I have at my disposal which will provide me with a serial -...

Any suggestions for a device which can RECEIVE files from mobile phones using bluetooth and/or wifi (at the same time, from multiple phones) without needing too much configuring? Will it need bluetooth and wifi modules separately or will it come with these in built? I know that we can plug in an USB stick in few devices and turn it into a file server but I need a device to act as more of a RECEI...

So for my capstone project I've decided on a myoelectric controlled (think robotic prosthetics) wireless computer mouse. From my little reading so far, I can avoid the pc side of the bluetooth stack entirely by conforming to the Human Interface Device profile on the device side. The way I read it, it should be basically connect and play, no drivers needed. I have some decent info on the analog ...

Hi All - Anybody have a recommendation for a ready-to-go Bluetooth module to connect audio bi-directional to an earpiece or headset ? I've already got the audio streams and I want to replace a profusion of speakers and cables. I don't want to add the protocol stack to the embedded controller, just need a ready-to-go "base station" module with audio input and output. Google turns up bluegi...

Hi all, I'm just curious. How many lines of code go into a typical modern cell phone? Probably more code than the entire Apollo space program. A Bluetooth module will add a wee bit of code, of course. The Bluetooth application that I use at work for serial communication weighs in at 400K bytes of ARM object code. I didn't count the LOC. -- Brad

Hi, I would think I have enough DSP knowledge and experience as a DSP firmware engineer. I even completed a WiFi physical implementation project, i.e. I know the WiFi packet structure etc. I also know basic TCP/IP, UDP definition and its application in embedded systems. My problem is about programming on WiFi or Bluetooth for an embedded system. I have quite several DSP evaluation board...

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...
