Hello! I have used bluetooth modules in the past with arduino. These modules are easily programmable via AT commands, but are slightly big in size. I want to use a smaller module which i would like to pair up with an android phone, and send sensor readings to the phone via the module. I found small modules here, Pan 1326, pan 1327 http://www.arrownac.com/solutions/panasonic-bluetooth/pdf/PAN-Arrow-RF%20Module%20Piece_web.pdf
Well this says that the module uses the HCI protocol. I earlier used the bluetooth module rn 42 which used SPP profile instead of HCI. For Rn 42 i just had to connect the UART of microcontroller to the UART pins on the module, and it transmitted whatever data it got from the controller. Here is the datasheet http://ww1.microchip.com/downloads/en/DeviceDoc/rn-42-ds-v2.2r.pdf My questions are 1. Will i be able to transmit data through Pan 1326 or 1327 , just by connecting the UART pins on the microcontroller to the module, or do i need to do something else as well? 2. How will I be able to pair this bluetooth module to the android phone? with rn-42 it was simple, just enter the passcode.
Here is the datasheet of Pan 1326,1327. http://www.pedeu.panasonic.de/pdf/174Datasheet.pdf
