Bluetooth Low Energy (BLE) is a wireless technology that has revolutionized the world of IoT development. It enables devices to communicate with each other over short distances without the need for a direct connection. BLE is a low-power, low-cost technology that allows developers to create connected solutions that can run for years on a single battery charge. BLE is an ideal solution for many IoT applications, as it can be used to create secure, reliable, and low-cost networks. Additionally, BLE's low-power consumption makes it an ideal choice for applications that need to run for long periods of time without sacrificing performance. BLE is an incredibly versatile technology and can be used for a variety of applications. From smart home automation to industrial process control, BLE has the potential to revolutionize the way we think about technology.
