to the UART of the BISM2 module. The module will attempt to make a connection and return connect
00809844ea13,1101) or (NO CARRIER), depending on whether the connection was successful.
The scope of the AT command set developed by Ezurio is such that most Bluetooth functionality can
be covered, greatly reducing development time.
To provide additional functionality a range of “S” registers has been implemented. These allow
program settings to be stored to control the BISM2 function and also give access to configuring and
reading ports and status registers within the BISM2.
Full details of the AT command set are provided in the Blu2i AT Command Reference Manual.
7.3.1 AT features at a glance
7.3.1.1 General
• Configure two modules to automatically connect and transfer data, audio or a combination of
data and audio when both devices are powered. The peer device does not have to be another
Intelligent Serial Module. It is possible to implement auto connect with a Bluetooth enabled
mobile phone.
•
Automatically re-connect devices when a connection is dropped.
• Remotely access the AT parser of the remote unit from a master device to perform Over The
Air (OTA) configuration.
• Configure the module to enter a state on power up and after a period of time change to
another state automatically. This allows units to be placed in the discoverable state for a
limited time period.
•
Read and write to GPIO lines
• Read the ADC channels
•
Get fast GPIO and ADC status through an inquiry response (patent pending)
7.3.1.2 Audio
• Set up audio connections
•
Enable / disable Auto Answer for incoming connections
7.3.1.3 UART
•
Change the baud rate from 1200 to 921,600 baud.
• Use the DSR line to drop connections
• Flexible configuration as either DTE or DCE
•
Change escape sequence character
• Change the number of Stop bits and Parity
• Enable or disable echoes
7.3.1.4 Security
• Enable Authentication by requiring a PIN code for incoming AND / OR outgoing connections
•
Enable data to be encrypted over the air for incoming AND / OR outgoing connections. The
module can be configured to be:
non-connectable and non-discoverable,
non-connectable but discoverable,
connectable but non-discoverable,
connectable and discoverable.
•
Automatically store Paired devices in a trusted device database in the flash memory
