I have noticed that many of the inexpensive Android tablets (7") do not have Bluetooth. (I guess that helps make them cheap) By cheap I mean under $100 w/free shipping. As the previous posting "Controlling embedded devices from tables apps", Tables are getting cheap enough to "buy one to use on a single project". But the Bluetooth limitation makes it harder to find one. Thanks, ...

We're going to synthesize some audio and want to transmit over Bluetooth from our embedded device to a Bluetooth headset. Also need to do SPP output. We can provide audio output over I2S or just serial. BC127 module can do this but is obsolete. Many modules can only act as slave for audio, and I'm defeated by vendor websites with lots of pretty photos and singing and dancing, but no cla...

hello , I am doing my final year project related to interfacing webcam(logitech quickcam express) and bluetooth-usb-dongle to LPC2106 microcontroller (based on ARM7TDMI processor) through usb host controller ,which transfers the static images captured by webcam through bluetooth.And further capturing the static images through the bluetooth connected at the PC end, and doing some image proce...

My company makes an embedded device which normally is controlled by a wintel host via RS232. The communication method is 8-bit binary, packet based, with no hardware flow-control (3-wire interface). I now have a new requirement: My device must communicate with a bluetooth enabled wireless host. The host may be either a bluetooth enabled wintel box(running winxp) or a PocketPC(windows CE). ...

I need to write data from my product using a Bluetooth connection. There could be multiple devices connected. I will need to be able to connect to either a PC or a Palm/PocketPC. I would expect that the BT module would act as an RS232 replacement. This will be a commercial application, but production volumes are low. -- ---------------------------------------------------------------...

Hello, I am new to bluetooth, I want bluetooth in my application to send data send to mobile. I want a Bluetooth Stack which should be port on my microntroller where my other application is runnning. I want to add this lwbt stack on my application to send selected data to Particular Mobile Device. My question is, 1. Is lwbt is platform dependent or independent. I am using stm32 controller, ca...

Hello, I have done some work with Bluetooth modules in the past and have connected them to microcontrollers. However, I am still unclear as to what the best module for my applications is. My main point of confusion lies in whether or not a "profile stack" is needed for simple data connections. For example, I can purchase a $70 module with built in SPP (Serial Port Profile) or a $6...

To date, most of my headless embedded development has been either entirely stand-alone, or has communicated with the outside world via serial. Serial is kinda old, and getting clunky. Yes, you can use a USB to serial converter from FTDI or whoever, but then you have a USB connection that needs to have a baud rate specified, which is just strange. On the other hand, USB and Bluetooth b...

I'm currently running an embedded (OK, a small) PC that collects data from the parallel port and sends them via bluetooth to a central machine. I'm considering changing to a 'real' embedded device, partly because I'd like the experience, partly because the power consumption of the PC is too high for the job it does and mostly because it's too big. The basic configuration I've sketched o...

Hallo, we want to implement a Bluetooth protocol stack to build a wireless connection between our software modules (Windows Embedded and microcontrollers). Has anyone had any experience with these companies: - BLUEmagic - IAR / Cybercom - Bluetopia (stonestreet one) - BOOST (Wipro-NewLogic) - aveLink (Atinav) - Broadcom - iAnywhere - BTE (Widcomm) Which of the solutions would you recomm...

I'm hoping to work with an extremely small circuit (half the size of a dime, and preferably smaller) that needs to talk to a bluetooth host over SPP. Money isn't an object yet, but it's fair to say that it needs to be available off the shelf, not a custom chip. My searches haven't done well, specific size doesn't seem to be part of the key words. If anyone with experience has suggestions or c...

Hi, i want to realize a bluetooth devive thath can be used to communicate with mobile phones, but i have no idea where to start...i have a lot of questions about: 1. What is the difference between HCI ad SSP? Only the second level can communicate with mobile phones? 2. Can you help me to find an embedded solution with this features (in order of importance)? * Open and free of charge st...

We're thinking about designing in a Class 1 Bluetooth chip, chipset, or OEM module into a device, and I'm having a difficult time finding quantity pricing. Does anyone have a feel for pricing in the 1,000 to 10,000 part range? Thanks! Al Cohen

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, Does anyone know of a small cheap ARM Cortex dev board with all of Bluetooth, Wifi and CAN onboard ? STM preferred but I can't find anything suitable in their lineup. Something with good SW support preferred to save me a porting expedition... Thanks, Mike
