Monitor Status of the Car with Phone

So how can we get the CAN data of the car?

What we are going to talk about today is not to add monitoring to the car or install a monitoring software APP to the mobile phone, but to view the motion data of the car through the mobile phone.

We know that there are several buses in a car to connect various devices, such as CAN bus, LIN bus, MOST bus and so on. The above types of buses have different characteristics, different speeds, and different connected nodes. Among them, the most important power part of the whole car is responsible for CANBUS, because this bus has low communication delay, strong anti-interference ability, and a large number of connected nodes. The company that developed this bus was the German company Bosch. What kind of role Bosch plays in the modern auto industry, I believe you know it without me having to say more.

As the power bus of the car, CANBUS is equivalent to the nervous system of the car. Any movement of the car will generate corresponding CANBUS data. Conversely, if we can obtain CANBUS data, we can know what the car has done by comparing the bus protocol. So how can we get the CAN data of the car? The conventional method is to connect a USBCAN analyzer to it and watch the monitoring through a laptop connection. However, this is clear, but not very convenient. If we can monitor it with our mobile phones, that would be awesome. As a result, the CAN to Bluetooth tool came into being.

The CAN to Bluetooth tool can realize the mutual conversion between the CAN bus data and the Bluetooth signal. We connect it to the car CAN line, and the generated CAN data will become the Bluetooth signal received by the mobile phone, and then converted into the corresponding information data . Of course, the above monitoring method is more suitable for projects with a relatively small amount of CAN data, and projects with a large amount of data often use a higher-speed transmission mode.
