This is a spin-off of the original irplus app for integrated IR-blasters to be compatible with any phone if you use a self-made IR-blaster for the audio port. Please note: - This app is only for a self-built blaster. Guide to build it: https://irplus-remote.github.io/?start=audio - If your phone/tablet has an integrated IR blaster use the original irplus application. (https://play.google.com/store/apps/details?id=net.binarymode.android.irplus) Warning: Use this app only if you know what you're doing, incorrect wiring of the self-made blaster can damage your device! If you have any problem or question about the app or about the building of the IR-blaster feel free to contact me via E-Mail ;-) Thanks!
