The HC-08 Bluetooth 4.0BLE Serial Port Module uses BLE (Bluetooth Low Energy) protocol. The main difference between Bluetooth and BLE is power consumption. Bluetooth consumes more power than BLE but can handle a lot of data. BLE is more appropriate for quickly transferring small amounts of data between nearby devices. BLE is less power-hungry, so the devices running this protocol can operate for years with a small battery; perfect for IoT!
HC-08 is a Bluetooth 4.0 low energy module, it can easily connect to iOS 5 and Android 4.3 or above by using a serial terminal app. You can use the Bluetooth communication up to 87 yards (80 meters) with this Bluetooth BLE module. It also runs on a 2.4GHz frequency. The chipset is CC2540 with 256K Byte space. You can change the role and serial baud rate and it supports AT commands for configuration.
HC-08 is a relatively new module made by an experienced Bluetooth design and manufacturing supplier in China. Its mass produced and therefore well-tested. It can be incorporated into products or projects without worrying about being able to get it again. It’s already widely used in many Bluetooth projects.
Note: The product dimensions may have ±2% error. Color also may vary due to light effect.
