WebUART (Universal Asynchronous Receiver/Transmitter): A UART (Universal Asynchronous Receiver/Transmitter) is the microchip with programming that controls a computer's interface to its attached serial devices. Specifically, it provides the computer with the RS-232C Data Terminal Equipment ( DTE ) interface so that it can "talk" to and exchange ... Web(Not the BT physical link speed). The maximum UART baud rate of this BT UART is just under 1 Mbps. This is the maximum throughput from the MCU (Host device) to the UART. Bluetooth 3.0 uses an 802.11 (wifi) physical link for data transfer, in the Bluetooth 4.0 spec this is refered to as the HS (high speed) mode. With the other two modes being ... thelma whitaker
