Figure 1:
The 1SPP firmware operates in one of two states. The states are called Command Mode
and Data Mode. In Command Mode, the 1SPP firmware assumes that data coming from
the UART are commands. The firmware parses the commands and processes them. In
this mode, feedback is given (provided it is not disabled via configuration) about the
status of the command.
Data Mode is entered when the device is attempting to make an SPP connection or has
been configured to accept SPP connections. The device is always in Data Mode when
there is an active SPP connection. There are two ways to enter Data Mode. One is by
entering the Bluetooth SPP Server command ( AT+BTSRV ). The other is by entering the
Bluetooth SPP client command ( AT+BTCLT ). While in Data Mode, everything that is
received on the UART from the host processor will be transmitted over the Bluetooth
SPP connection and all data that is received from the Bluetooth SPP connection will by
transmitted to the host processor. Thera are two ways to enter Command Mode from
Data Mode. The method used depends on how the device is configured).
In the first method of entering Command Mode from Data Mode, the host processor
instructs the device to go into Command Mode. This can be done by the host processor
issuing the escape sequence, or by the host processor lowering the DTR or DSR signal.
The signal to lower depends on whether the device is configured to be a DTE or DCE
