The HM-10 Bluelink RS232 is a low cost,easy to use Bluetooth 4.0 module which communicates using RS-232 protocol used for establishing wireless data connection.The HM-10 Bluetooth module combines the powerful and programmable Texas Instruments CC2540/CC2541 Chipset with the required components to start right away for the BLE development.The module offers an on-board voltage regulator and is 3.5 V tolerant. The Bluetooth-SoC can be accessed via UART interface and supports AT-Commands for setup. It supports full Bluetooth 4.0 standard and can be used for your Arduino or microcontroller to Android or iOS communication projects.The device becomes ready to use by plugging in the adaptor and RMC cable.

It has two modes of operation, namely AT command mode and Data communication mode. In AT command mode, we can configure the different control parameters which finally determine the working of the module. In this mode we can’t communicate with other devices. In Data communication mode, the device works as per the settings previously defined by the user in AT command mode and can communicates with other devices.
