Interfacing a bluetooth module with uc
BlueLINK - Bluetooth Module (5V Serial UART) : rhydoLABZ India , Your Source for Robotics & Embedded System
to interface with the uc and use as if like a normal RS232 interface and communicate with hyperterminal ?
first of all you need to convert to ttl level using max232. After that pair it with another bluetooth device. Note down the incoming and outgoing ports. Connect the device in one of the port. Then you can send data using that module
means the COM ports in device manager ? ,
sending data is like the regular RS232 port ? ,
This module is provided with the " 3V3 to 5V level converter required to interface with 5V Micros " , so i need a max232 ?
no, i mean that if you are connecting the bluetooth module to the pc then you need the converter. The ports mean, you can see two ports for a bluetooth device. One is to send the data and another is to receive data. One me the port will do the two functions (rx & tx). It may be the in port or out port. Which is that, i am not sure
i want to connect the module to the uc and it is connected wirelessly to the PC via bluetooth dongle , the module is provided with the GND, VDD and Rx and Tx (see the pic provided there) , to connect to the uc , is that , i need only that pins from the module to the equivalent (Rx-Tx) and (Tx-Rx) of the uc ?
yea through the usart module you can send data
As the bluetooth module is providing the UART module and the 3v3 , 5v converter etc , do i really need a level shifter like max232 ?
no, you should not. Just connect the rx of bluetooth module to tx of pic and tx to rx
