Bluetooth 4.0 AT-05 BLE Module compatible HM-10, with this module the MCU, can be set up, controlled, transfer data, and can remotely control 10 PIO pins, so, the best choice for BLE Device is Bluetooth 4.0 AT-05 BLE Module compatible HM-10. Support Slave and Master mode you can switch, and modify by the AT commands. it Supports Remote control mode, the remote device can control the PIO pin or modify settings by AT commander when Connected. (such as Iphone4s/5 iPad, Note2, etc.) The Bluetooth UART RS232 Serial Converter Module can easily transfer the UART data through the wireless Bluetooth, without a complex PCB layout or deep knowledge in the Bluetooth software stack, you can combine this Bluetooth module with your system for cheap and on the go.
