Bluetooth Module HM11- CC2540


This BLE4.0 module is based on the CC2540 microprocessorit can be used to communicate with desktop computerssmartphonestable computers and even other embedded systems providing Bluetooth Smart aka Bluetooth Low Energy (BLE). It's highly customlized chip with AT comand supported. You can modify the role (masterslave mode) and the serial port baud ratename of equipmentmatching parameters such as passwordsuse agileeven the transmission power bwtween - DBM23-6 DBM0 DBM6 DBM.     Besidesthere have been large quantity of Resource& Demos of development material& tools are provide to help IOS and Android developers to develop BLE4.0 related appsit will greatly helps for your development.For prototyping or learningyou can also choose the EB Verison of this module to make it easier to use.
