We are the leading suppliers for Bluetooth Module HM-10 Low Energy 4.0. This Bluetooth Low Energy 4.0 Module utilizes a HM-10 module to provide your Arduino with an easy to use wireless link between your Arduino and any compatible iOS or Android (4.3+) device. It works by simulating a UART device beneath the surface, sending data back and forth between the devices, letting you decide what data to send and what to do with it on either end of the connection.
This module supports two operating modes: Central and Peripheral mode. By default the module is in Peripheral mode. Once it is paired to a Central device such as PC, smart phones or tablet, its operation becomes transparent to the user. All data received through the serial input is immediately transmitted over the air. When the module receives wireless data, it is sent out through the serial interface exactly at it is received. No user code specific to the BLE module is needed at all in the user microcontroller program. When the module is configured to Central mode, it can be used to scan and pair to other BLE device in Peripheral mode.
