Abstract
Communication is important in human life, because communication can bridge all forms of ideas to be conveyed by someone. And the communication media commonly used today are via mobile phones, which can be via sms messages, whatsapp or telephone. The problem is, in some areas the absence of signals or blank spots is a problem for those who rely on communication via mobile phones. For this reason, it is necessary to optimize the short message media in the arduino and bluetooth-based blankspot areas. Here the main goal is to make it easier for humans to communicate via mobile phones even in difficult conditions and without a data packet or WIFI signal. The tools used are android, the Lo-Ra module as a long-distance wireless transmission technology platform that can reach distances of 10km and then also use the Arduino Pro Mini as a microcontroller board and Bluetooth terminal that functions to transmit data from android to arduino and then forward it to Lo Ra. From the test results it was found that this tool works well in the blankspot area or difficult to signal, without the need for data packages or WIFI we can still communicate well through the short message media on the cell phone.
