need of time and situation.
Over the few years, there are many things changed including data
transmission rate, power consumption with wearable and IoT Devices and
Security System.
Here we are going to learn about HM-10 BLE 4.0 with Arduino Board. The
HM-10 is a readily available Bluetooth 4.0 module. This module is used for
establishing wireless data communication. The module is designed by
using the Texas Instruments CC2540 or CC2541 Bluetooth low energy (BLE)
System on Chip (SoC).
