The plug & play 2xCAN/LIN logger records timestamped CAN data (Classical/CAN FD) to the extractable 8 GB industrial SD card.

The small device connects via WiFi access points (e.g. WLAN or 3G/4G routers) to securely push data to your server. Further, the device can be updated over-the-air.

Ideal for telematics, R&D field tests, diagnostics and predictive maintenance.

Software/APIs are free & open source - with no subscription fees or vendor lock-in.

DATA LOGGING
SD Card 8 GB extractable Class 10 industrial micro SD (SDHC) included (optional 32GB) - read at 80 MB/s  
 i 

Parallel CAN/LIN Record data from up to 2 x CAN channels + 2 x LIN channels, simultaneously
Real-Time Clock Yes - CAN frames are date & timestamped with 50 microsecond resolution (battery backup)
The RTC can be configured to match local time zones (default: UTC)
Log File Format Log data in industry standard binary MF4 (easily convert to e.g. CSV, ASC, pandas, MATLAB, ...)
Data Compression Configurable embedded log file compression (~50-80% size reduction)
Silent Mode Configurable silent mode: Restricted (acknowledge only) or monitoring (zero transmission)
Filters 128/64 regular/extended ID filters per channel (range, mask, acceptance, rejection)
Prescaling Prescale CAN frames to record e.g. by time (per X ms) or by data (e.g. if byte X or Y changes)
Transmit Transmit lists of CAN frames per channel (single-shot/periodic) - e.g. for OBD2 requests
CAN Error Frames Support for logging CAN error frames (bit-stuffing, form, CRC, bit, acknowledgement)
LIN Error Frames Support for logging LIN error frames (checksum, receive, synchronization, transmission)
Remote Frames (RTR) Support for logging/transmission of remote CAN frames (RTR)
Cyclic Logging Optional cyclic logging mode (oldest log file is deleted when SD card is full)
Advanced Triggers Control signal lets you start/stop logging based on custom CAN IDs & data thresholds
CAN Heartbeat Optionally transmit heartbeat CAN frame with device status, storage used & RTC time
File Split Configurable log file split size (by size: 1-512 MB and/or by time period: 0-86400s)
Power Safe 100% power safe data logging - no file corruption when disconnected
Unique Device ID Each device has a globally unique ID ensuring unique log file naming
Data Encryption Log files can be encrypted at rest on the SD card for security/GDPR/CCPA (incl. integrity check)
WIFI
Transfer Modes Station mode: Connects to a WiFi access point (e.g. a router or 3G/4G hotspot) to transfer data
Protocol HTTP/HTTPS: Stable and secure transfers - ideal for big data telematics
Access Points Add 1-5 WiFi access points. Prioritized order. Condition on signal strength
Over-The-Air (OTA) Configuration & firmware over-the-air (COTA/FOTA). Configurable sync rate. Optionally disable
WiFi Heartbeat If enabled, the CANedge2 periodically "checks-in" by uploading a small device status file
Data Upload State Optionally disable/enable upload of log files (e.g. via over-the-air configuration)
Range Strong range via external WiFi antenna
