1. Overview
1.1 Introduction
The CAN WIFI odule is a hybrid device with two co pletely separate sub-syste s connected internally
via a UART interface.
One side is the CAN interface with the COM port interface hard-coded to 921,600N81 with RTS/CTS flow
control enabled. The CAN interface can send and receive CAN essages on an ISO11898 CAN network.
The other side consists of the xPICO WiFi odule. The configuration for this odule is done via an Internet
browser. Once the unit has established a connection via its own unique SSID, the browser can be used to
login to the xPICO directly and perfor configuration.
The CAN side is based on an ARM Cortex-M3 32-bit icrocontroller, providing 100 MIPS of processing
power with an extre ely efficient instructions set.

1.3 CAN Network
Before trying to send co ands to the CAN WiFi, ake sure the unit is attached to a valid CAN network
with at least one other node attached and running. Without another node on the network, the CAN WiFi will
atte pt to trans it the essage indefinitely (as per CAN 2.0A/B specifications).
Make sure there are ter inating resistors on the network. A ter inating resistance of 120 oh s is
appropriate for ISO11898 drivers. Atte pts to co unicate over the CAN network without ter inating
resistors can lead to erratic behavior and any long hours of trouble shooting.
CAN ISO11898 specifies a three wire bus: CAN_H, CAN_L, and GROUND. Failure to provide a co on
ground between network nodes will create so e weird behavior. CAN_H and CAN_L for a differential
pair and each one ust be referenced to ground in order to work properly.
