Hello, I'm planning to use Bluetooth in a medical device I'm developing. The device is already based on a MCU (STM32) and is powered by mains. The device will provide only the File Transfer profile sevice: it will act only as a server providing one or more files that a client can download (no modifications or upload on the server possible). I would like a bluetooth solution (single-chi...

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, ...

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). ...

Has anyone used or have a particular MCU that they would recommend for a personal area network application using Bluetooth? I have seen the Texas Instruments CC2540, which seems intriguing but I was curious of other options and the potential experience someone may have had with these types of devices.

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. -- ---------------------------------------------------------------...

Hi All, I am developing a Bluetooth image/video project. I have tested CSR BC2 ( will test BC4 these days, and waiting for BC5 ), the speed is very low. BC4 and BC5 are EDR version, BC2 has no EDR. My test result on BC2 SPP is about 150KB when I set the UART of Bluetooth is 460.8Kbps. Our another project has got about 320Kbps on A2DP with BC4. I never use a Broadcom chip, did y...

Have a LOW-volume mobile data acquisition application that requires Bluetooth. Not sure yet whether it will be Class I or II. Any suggestions as to good, reliable OEM modules?

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...

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...

I am using some Bluetooth modules and it is important that the devices are paired uniquely. The product needs to meet all the regulatory requirements for the FDA and I was told by a friend that they will not allow pairing of devices based off a software key. My understanding was that there had to be a hardware key (dongle, sdcard) or something on the device to be sure there are not mistakes...
