The New Filtering Function of GCAN Bluetooth to CAN Device
Bluetooth to CAN module firmly occupies a place among the dazzling CAN bus converter devices with its unique convenience. For example, GCAN-203 device as a very mature Bluetooth to CAN product can realize data transmission between Bluetooth and CAN bus. Users can access CAN node and read data from it only by using handheld mobile device(Mobile phone/PAD). In difficult physically connected CAN network, it will be very convenient to use GCAN-203 Bluetooth to CAN module to exchange data from CAN network through wireless terminal. So the filtering function is very important.
However, the communication speed of Bluetooth is slower than CAN bus, so the Bluetooth to CAN device on the market can’t be connected to CAN bus with large amount data(such as automobile CAN bus system). If connected,some data must lost certainly.
In view of the widespread existence of this problem, engineer Sun of a car parts manufacturer contacted us to say whether CAN data filtering function could be added to the existing Bluetooth to CAN module. In order that the handheld mobile terminal they developed could be connected to automobile CAN bus monitoring the real-time parameters of some car internal sensors.
With the hard work of Guangcheng technology enbineers, the filtering fuction of GCAN-203 Bluetooth to CAN device was finally born. Here’s some new functions below:
1.The filtering function of GCAN-203 only filters data sent from CAN to Bluetooth,not filters the data sent from Bluetooth to CAN.
2.The filtering function filters according to CAN data which can set single ID or ID segment, up to 10 groups filtering can be set.

The new filtering function can directly solve the problem which Bluetooth couldn’t deal with the large amount data of CAN bus.If the customer knows the data ID he need, he can configure the Bluetooth side only receiving data needed. Filter settings can be adapted to varieties of situations and used flexibly. When the customer want to set up GCAN-203 devices in batches, he can save the Bluetooth configuration files then configures the Bluetooth devices in batches, saving time and improving efficiency.
