After pairing, it can be used as a full-duplex serial port, without having to know any Bluetooth protocol, but only supports 8 data bits, 1 stop bit, no parity bit communication format, which is the most commonly used communication format. It does not support other formats.
When Bluetooth connection is not established, you can set the baud rate, name, passkey via AT commands, parameter settings will be saved at power-down. After Bluetooth connection, it will automatically switch to transparent mode.
Module role: Slave module. It can be paired with PC, Bluetooth hosts, most Bluetooth phones, PDA, PSP and other intelligent terminals whose Bluetooth is enable.Slave devices can not communicate with each other.
