1. OverviewofTheController
Figure 1 – AX141100 Block Diagram
The CAN to Bluetooth device (later CAN2BT) can be used for accessing the CAN bus and the other
CAN nodes connected to it using Bluetooth communications and a smart device, such as a phone
or a tablet.
The CAN2BT device provides also data logging capabilities. It has 4GBits of internal Flash storage
for storing the selected CAN messages with time stamp information.
The CAN2BT device can be configured using an Android application called CAN2BT Configuration.
With this tool, all the functionality of the CAN2BT device can be configured, such as setting PIN
codes, connection options, CAN receive filtering and CAN data logging rules. Also RTC time setting
and different Flash memory operations such as download data and data erase are supported.

The CAN2BT device can be operated in two main operation modes, namely the Interface Mode and
the Bridge Mode. The Interface Mode is targeted for data logging operation and in this mode the
CAN2BT device can be accessed using Electronic Assistant.
When in Bridge Mode, the CAN receive filtering is disabled and the device accepts all incoming CAN
frames. The main purpose of the Bridge Mode is to use two CAN2BT devices as a wireless CAN
data bridge between two different CAN networks. When in Bridge Mode, the CAN2BT device is
transparent to the CAN bus and cannot be seen in Electronic Assistant’s list of J1939 nodes. The
device can be still accessed using the CAN2BT Configuration tool.
In case the module startup fails (a communication error between the CPU and the Bluetooth module
is detected), the CAN2BT device will indicate the failure by sending the following DM1 (PGN 0xFECA
/ 65226) to CAN bus on 1s intervals. In addition to the DM1, the two built-in LEDs are blinking and
not responding to user configuration nor control messages. In failure mode, the unit will be accessible
only via the CAN bus.

2. CANtoBluetoothFunctionBlocks
This section explains the different functions and configuration available on the CAN2BT. The
CAN2BT Configuration Android application is used as a reference. The application is available from
Google Play.
2.1. PINcodes
Figure 2 – PIN Code settings
The PIN Code settings allow the user to define PIN codes that are used when accessing the device.
Pairing PIN is the PIN code that will be used when pairing the CAN2BT device with a new smart
device. Configuration PIN code is required when configuration is accessed (most configuration
options require that the CAN2BT device is put to configuration mode. Entering the configuration
mode requires the user to enter the configuration PIN). Remote Connection PIN is the code that is
used when the CAN2BT makes a connection with another CAN2BT device (when forming a data
brigde for wireless CAN communications).
