I'm trying to develop a bluetooth interface between my PIC32 board and my computer. I'm new to embedded bluetooth so I'm having some trouble finding good transceivers. I've found one that follows SSP (Serial Port Profile), and I like it very much, but I'm not sure if it's compatible with the PC bluetooth. Could you help me giving me some information about the most common bluetooth profiles...

Hi All, I am studying Bluetooth security protocol these days. I found that there is no much specified data about protocol detail/procedure. I think, when I finshed the study of Bluetooth, I can only know more about Bluetooth operation, but I still can't develop a Bluetooth related tools, is that right? Best regards, Boki.

Hi, I have some general questions on bluetooth and embedded system before I am able to go into a more details questions. Below is some specifications that I needed for something I have in mind: 1. I need to build a master bluetooth "router" which connects with some bluetooth devices and the bluetooth router connects to a LAN through cable or wifi. 2. I need to support bluetooth 2.1 which ...

Hi all: I am a newbie about Bluetooth development, I am debugging a board which contains bluetooth chip(LMX9838), and have some questions about the principle, I will be very appreciate if anyone can answer all or part of my questions. 1 The is a mode called "transparent master/slave", my understanding about this mode is, if I have two bluetooth module, and make them both work in this mode, t...

I want to develop a embedded system which has bluetooth capability (that is, overall system = a microcontroller + bluetooth component), so it can talk to a bluetooth-enabled PDA. So which chip should I choose for the bluetooth component and also what microcontroller is good for the embedded system? Thanks in advance. SWH --

Hello! We want to connect some mobile systems via Bluetooth at an university project. But it seems not so easy to find a suitable Bluetooth module. In most cases there's a minimum order quantity of e.g. 1000. But what I'm looking for is something simple and cheap, where I can buy just 1 for testing and then some little more. Does anyone know whre to get such small numbers of chips? I s...

Has anyone used these Bluetooth modules ?? http://cgi.ebay.com/2-PCS-Wireless-Bluetooth-RS232-TTL-Transceiver-Module-/200523926482 I have been googleing for PC application code examples, but I have not found a good search term. C# would be my source of choice, but MS C++ would also work. Thanks for any informations. hamilton

Hi Folks- I have a Bluetooth inquiry/response connection problem for which I suspect there is a classic solution. I just can't seem to find the answer so I hope somebody here can offer a solution. The problem domain is Bluetooth but I don't think that should be a limiter in finding the solution. Device A and B are Bluetooth devices that must find each other but only one can be th...

The time has come when I have to choose which Bluetooth and which wifi chip/module to use. After may be a whole days browsing/searching, I seem to come to the following conclusions: Bluetooth is available from more than one source as a single package solution, some of them are documented and really ready to use. I tend to stop at NSCs part, LMX9830 - stocked and inexpensive at Digikey, pl...

Hi everybody, I am a newbie to the microcontrollers world. So, I need every help that i could get. I want to use bluetooth communication with an ATmega32 mcu, but i don't know which bluetooth module is good and at the same time cheap. Could anybody recommend a module and tell me why does he recommend it? I mean what's its pros and cons? Thanks in advance.

Hi, Can anyone recommend an inexpensive bluetooth module that one can connect to a MCU via the serial, SPI or I2C port. I do not want to write the prorcol stack myself. I should be able to use simple commands to the module, and the module should handle all the protocol specifics of bluetooth. Regards Anton Erasmus

I'm looking for a self-contained Bluetooth LE module. Does anyone have any suggestions on an easy to use device? I stumbled upon the OLS425 from connectBlue. Has anyone used this device before?

This may be a naive question, but I have an idea for a Bluetooth application, and need some help in either sourcing or building the units. What I need is 2 devices - a 'Host', and a Remote unit - as small as possible - that connect to each other over bluetooth. All they need to do is 'know' that the other is there - within a given range (5 mtrs). If the remote moves out of this range - o...

I'm looking for advice on embedded bluetooth. I know there are complete RS-232/Bluetooth modules for use on PCs, but space constaints in my app requires a smaller form factor. Ideally, I would like to interface it to a PIC using the async pins directly (not RS-232). Any suggestions? -Robert Scott Ypsilanti, Michigan (Reply through this forum, not by direct e-mail to me, as automatic r...

Dear All, The whitening word " in the bluetooth standard" is generated with the polynomial g(D) = D^7 + D^4 + 1. Also the circuit is represented in the standard whcih is saying that the shift registers shall be initialized with a portion of the master Bluetooth CLK, CK(L6-1). I have no idea how to get the initial values for the shit registers from this CLK. Does anybody know ?? Tha...

Hi, I am searching for a module which provides an encapsulated bluetooth interface - the connection doesn't really matter but a serial interface would be fine. The goal is not to have to mess with bluetooth certification, stack development, antenna issues etc. It will be a low bandwidth application, no audio or anything that requires high data rates. I'm talking higher quantities (seve...

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...
