Custom Bluetooth firmware

The newest generation of Bluetooth adapters use a custom Bluetooth firmware that has HC05 compatible commands but without the requirement of setting the mode pin for configuration. All commands have to be terminated by a <CR><LF>.
It's also possible to configure the device via the Bluetooth interface, to activate this mode the first command after connection has to be AT+CONF.
In contrast to the UART interface the commands via Bluetooth interface must be send in one telegram.
The firmware supports the following commands:

• AT: Simply responds with OK.
• AT+ORGL: Performs a factory reset. The default values are: Baud rate=115200 8N1, Name=Deep OBD BMW, Pin=1234. The settings will become active immediately.
• AT+RESET: Resets the Bluetooth firmware without changing any values.
• AT+CONF: Switch the Bluetooth interface to configuration mode. This must be the first command after connecting, otherwise the devices switches to transparent data mode.
• AT+DATA: Switch the Bluetooth interface to transparent data mode. This command is only valid for the Bluetooth interface.
• AT+PSWD?: Read Bluetooth pin. The response is +PSWD:<pin>.
• AT+PSWD=<pin>: Write Bluetooth pin. The minimum pin length is 4 and the maximum length is 16 digits.
• AT+NAME?: Read the Bluetooth name. The response is +NAME:<name>.
• AT+NAME=<name>: Write the Bluetooth name. The maximum name length is 31 chars.
• AT+UART?: Read the UART settings. The response is +UART:<baud rate>,<stop bits>,<parity>. Possible baud rate values are: 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600, 1382400. The coding for stop bits is: 0=1 stop bit, 1=2 stop bits and the coding for parity is: 0=None, 1=Odd, 2=Even.
• AT+UART=<baud rate>,<stop bits>,<parity>: Write the UART settings. The settings will become active immediately.
• AT+VERSION?: Read the Firmware version. The response is +VERSION:<version>.
• AT+FWUPDATE: Switches the device to firmware update mode. In this mode firmware update is possible via UART interface using the BlueSuite tool DfuWizard. The interface setting in this mode is BCSP 115200 8N1.
