hello guys ,
can anyone help in this ??
i want to connect a 16f877 pic to a bluetooth circuit..
all what i need is to transmit data through bluetooth ,, it will be an analog signal and the 16f877 will convert it to digital and send it via bluetooth
We recently used a Stollmann BlueMod B20 in a similar application. You can interface it in a number of ways, e.g. USB, UART, SPI, etc. We used UART as the simplest, see the hardware manual for details www.microem.ru/pages/bluetooth/stollmann/B20.pdf
Thank you Mr. Horace1
this sounds great..
then i dont need to design an electrical circuit ... right ??
can it be used to send data from "Temp. sensor or blood pressure device "
i hope you can help with this thing..
you will find plenty of circuit designs either on the Microchip site or by searching the internet which will do what you require.
for a temperature sensor for humans we have used the TC77 which has an SPI interface to attach to a PIC

Don't know about blood pressure - there are plenty of blood pressure monitors but we never found one suitable to interface cheaply to a microcontroller – if you find anything let me know
do you intend to build your own PCB or buy a development system?
This thing is my graduation Project..
(Real time mobile application)
which aims to transmit the analog signal after digitizing using the pic and transmitting using bluetooth .. i have to create an ANDROID application to receive the data and build an interface that would help in reading the received data..
i've decided to use a temperature sensor..
i've built a circuit using ( BC352239A bluetooth ) and ( 16F84 PIC ) but still have to read more to know how can i get the sensor reading to the PIC to send it ...

I know it is an old topic, but I can see some relatively recent activity, so I thought I should give it a try.
I am in great need of information about the Stollmann+C11/G2 bluetooth module. I have bought a few pieces and don't seem to be able to find a clear wiring diagram that would allow me to pair it with a PC. An important aspect is that the modules came without an onboard antenna. I have desoldered one from a Logitech bluetooth keyboard and soldered it straight on the pads of my module.
According to the pinout diagram found on the Stollmann website, the module needs 3.3V on pins C13 and C16 and GND on pins C14 and C15. I have used a 3.6v battery for that (the voltage is still within the limits according to the datasheet), but neither the PC nor any other mobile phone/tablet can find the bluetooth device to pair with.
Can anyone point me in the right direction to, at least , be able to pair the module with my PC and put up a serial communication between them? What I need exactly is a wiring diagram to get the module "alive".
All the details about the module are on this page, right underneath the price : **broken link removed**
If uploading the PDF files is more helpfull, I will do it.
Hi! No hints, guidelines, maybe some schematics...? I just need to power on the module and get it "visible" for the PC. Here are some photos of the module with and without my "scavenged" antenna.
