FSC-BT826E Bluetooth 4.2 dual mode
1 Core module HC-06, leads to interface includes KEY ,VCC, GND, TXD, RXD, STATUS.
2 led Indicates Bluetooth connection status, flashing Bluetooth connectivity means no, Always indicate Bluetooth connection and open ports
3, floor 3.3V LDO, input voltage 2.8V ~ 3.3V.
4, open to the effective distance of 10 meters
5, FSC-BT826E works in throughput mode by default.
Tips (very important):
TXD: Send side, generally expressed as their own sender, normal communication must be connected to another device RXD.
RXD: the receiver, generally designated himself on the receiving end, normal communication TXD must be connected to another device.
When normal communication itself TXD RXD always connected device!
Since the resumption of spontaneous: RXD when normal communication TXD connected to other devices, so if you want to receive data sent by itself as the name suggests, is to receive the data they transmit their own, that is directly connected to its own TXD RXD, used to send and receive test itself It is normal, is the quickest and easiest way to test when there is a problem to do the first test to determine whether a product failure. Also known as the loopback test
Throughput mode (when TPMODE=1) means that there would be transparent transmission after Bluetooth connection established.
After power on and initialization completed, FSC-BT826E automatically enters AT-command state, then the host MCU can send AT commands to the module. When the module gets connected with another Bluetooth device, it automatically enters throughput state, every byte received from the host MCU will be entirely delivering to remote Bluetooth device without any change, so does the reverse direction. In other words, the FSC-BT826E enters AT-command state when disconnected, enters throughput state when connected.
AT-command mode (when TPMODE=0) means that FSC-BT826E works in AT-command state at any time after power on and initialization completed.
