As I develop my R&D project I decided to add bluetooth to the mix... In the first stage I decided to use my own iMac as a transmitter and my iPhone as the receiver, and it worked great...

As I finish this early stage and start to think about field testing, well, I can't carry my 20' iMac around, so I would like to build a low-cost bluetooth transmitter.

My question is: Do I need something like a Arduino/Raspberry or there are "self-contained" transmitters?

Details:

  • The transmitter will be plugged into a reliable power source
  • The message being transmitted will be fixed and very short (20 bytes max)
  • The programming part is: while(true){ transmitMessage("myId",sleepInterval); }
  • The ideal answer here is something like: "Buy this guy here, download IDE X or Y or Z and here's a Transmitting Hello World Example"

    \$\begingroup\$ You could make your own device very easy. Just buy an atmega328ppu which is used by the arduino uno. A 16MHz crystal. 2x 22pF capacitors. A resistor and button to make a reset possible. And the Bluetooth module of course. You can get a Bluetooth module HC-05 for around $5 from eBay. But for prototyping I'd suggest to buy an Arduino uno when you want to use an atmega328ppu as MCU \$\endgroup\$ – Handoko Jun 4 '14 at 19:43
  • \$\begingroup\$ @Handoko wow that sounds great and very cheap! i'm very n00b in this eletrical eng area... i'm a dev... can i contact you via email or something for further clarification? \$\endgroup\$ – Leonardo Jun 5 '14 at 16:55

I think you should look at:

  • BLEduino (http://bleduino.cc/)
  • BLE mini or Blend Micro (redbearlab.com)
  • Possibly RFduino (Be aware thats it is NOT open source or open hardware)
