See CAN data on a smartphone, via a WiFi-gateway

April 16, 2014 // By Julien Happich
With IPEhub2 and the IPEmotion App, Ipetronik enables users to visualised CAN data on a smartphone or tablet using a WiFi connection. IPEhub2 acts as CAN-WiFi-Gateway and transfers CAN bus data (from the company’s CAN modules or the vehicle CAN bus) using WiFi.

Two CAN bus data streams are converted to encrypted WiFi data and wirelessly transferred to a tablet or smartphone running the IPEmotion App according to WiFi Standard 802.11 a/b/g/n. IPEmotion 2014 features an IPEmotion App export, so custom IPEmotion configurations can be used in the Android application conveniently.

Data visualisation type and extent (curve, bargraph, alphanumeric, LED) are to be set individually via IPEmotion App. Parallel to wireless data transfer, traffic data are stored on the FIFO of the SD card included in IPEhub2. Customers can choose between SSID (Service Set Identifier) and WPA2- (WiFi Protected Access 2) encryptions; WPS- (WiFi Protected Setup) function is supported for initial setup.

The IPEhub2 module measures 106x43x62 mm, is protected to IP54 and can operate in the -40 to +85°C temperature range. It runs from a 9 VDC to 36 VDC voltage supply, drawing 4.0W typically. Two multi colour status LEDs indicate operating states of WiFi (signal strength) and data storage (memory usage). IPEhub2 also supports Access Point functionality with DHCP server and a CAN2 terminating resistor that can be connected via software.
