🔥Hice mi propio WhatsApp SIN Internet | 100%📡Funcional a kilómetros con LoRa🚀

#technologyforall #lora #WhatsAppWithoutInternet I built a WhatsApp-style communication system without internet, using two Reyax RYLR999 LoRa BLE modules, App Inventor, and Arduino. I managed to send and receive messages over kilometers and built a mini communication tower with toothpicks and wood to test the range. An amazing project for makers, students, and curious individuals who want to create their own offline messaging system. Real technology explained step by step!
