Wireless Multi Zone Infrared Extender Solution

In this Blog post I will discuss some possible usage scenarios for Wireless Multi Zone Infrared Extender solutions. When a Multi Zone Infrared Extender is needed?

Example Usage:

  • Extending and splitting the Infrared signal in big premises
  • Big exhibition halls
  • Big Shops / Malls
  • Apartments
  • Stadiums

The Multi Zone Infrared Extenders are used to extend and split/multiply the infrared signal, thus allowing remote control of Displays/STBs/TVs from a centralized location. The usual setup consist of at least one Transmitter unit and two Receiver units. The transmitter captures the Infrared signal, emitted from the remote control, converts it to wireless signal which travels down to the receiver/s . The Receiver/s convert the wireless signal to infrared signal which is emitted to the target equipment, such as Air Conditioners, TVs, STBs, Monitors.

Extending Infrared Range with Irdroid

Below you will find a link to a Blog post in our EU website for how to extend Infrared Range, in cases where your STB , Audio or any other IR controlled Equipment is inside cabinets, cupboards or behind walls.



Irdroid irDA NEW Product range





















We have developed four NEW irDA SIR modules that cover irDA SIR Specification 1.3 and it allows communication with irDA compliant devices with baud rates from 9600 – 115200 .

Four new modules were developed:

New Firmware for the Irdroid USB Infrared Transceiver v2.5

Today (12.06.2018) we have released a NEW firmware version 2.5 for the Irdroid USB Infrared Transceiver module. The new firmware introduces two new modes – separate transmit mode and separate receive mode. The Idea is that the sampling mode was sometimes causing problems on Android (USB Stalls/ USB Replug needed in some cases) and therefore we had to think about a solution backward compatible with the software for the other Operating Systems and at the same time stable on Android (the sampling mode remains unchanged/ the one initiated with the text command ‘S’ ).

To enter transmit mode the Irdroid USB App issues the text command “n” over serial and the module enters transmit mode. To enter receive mode the command used is ‘m’ and the module enters in receive mode. The other mode – sampling mode remains unchanged , initiated by the ‘S’ text command.


Playing with Arduino Irdroid and Car Halo light led controller

The Car Halo LED Light controller is controlled using a cheap remote control using a EV1527 Encoder chip, which is compatible with the Arduino / Raspberry Pi  rc-switch library. I has able to clone the remote control buttons using a cheap RF radio transmitter and receiver AM modules, working at 433MHz. Then I was able to control the Car Halo Light led controller , using the Irdroid IoT SmartHub.

NEW Product in Stock- Infrared (IR) Proto Shield for Arduino

The latest gadget in our online store is the Infrared (IR) Proto Shield for Arduino. It can be used to prototype and experiment with Infrared on Arduino. The board comes with a High Power IR LED, High Quality IR Receiver IC , SMD and BreadBoard prototyping area.

Manually parsing a Lircd.conf file in the Irdroid App.

In some cases, the automatic “update db” option will download automatically the default licd.conf file that ships with the Irdroid v.0.4 app, but it will not parse it in the UI. In this case you can use a “File Manager” application like this one to locate the downloaded database file. It should be downloaded and stored in your internal SD Card under the /sdcard/tmp/ folder. Locate the file named “t.conf” and copy it to your external SDcard under /tmp folder (create /tmp folder if it doesn’t exist) . Using the file manager tap on additional info when the t.conf file is selected and write down the full file path shown in the “additional info” (you will need it later in the Irdroid v.0.4 app) . Start the Irdroid app and select “Parse File” and enter the exact path to the “t.conf” file. Once done, the default remote brands will show up in the list of devices.

Irdroid Branding Graphic


Irdroid started as a Hobby Project, founded by Georgi Bakalski back in 2011. Today the Hobby project transformed into a Innovative and Successful Company (Hardware Group Ltd.). We believe in the open source initiative and we started the project as a open source hardware and open source software. During the years we have developed, devices and software for GNU Linux, MS Windows, Mac OS X, Arduino and more. We believe that learning by sharing is a key for the progress. Today Irdroid is a registered trademark of Hardware Group Ltd Bulgaria and it provides open source hardware and open source software devices and software development services for Google Android, GNU Linux , Windows and Mac OS X . Our Devices and services help hundreds of individuals and StartUp Companies around the world to bootstrap their new products and ideas.

We would like to thank all our Customers during the years, they are the one’s that kept the project up and provided precious feedback for improving it.

Thank you!
