CAN Bus Bolt Connects Industrial Machinery And Devices to Wireless Networks, WiFi And Bluetooth
Posted by on
HMS Networks introduced its Anybus Wireless Bolt CAN gateway, providing CAN Bus communication via WiFi or Bluetooth. The device builds on the success of Anybus Wireless Bolt, which is applied to wireless Ethernet access. Like its predecessor, the gateway for bolt-on-machine mounting is suitable for heavy-duty machinery and demanding industrial applications. Applications include warehouse installations and AGVs (Automated Guided Vehicles) for food production, mining, and other rugged outdoor purposes.
The wireless bidirectional communication is performed via WiFi or Bluetooth using a TCP/IP link. A standard use case is the wireless access to SAE J1939-based in-vehicle data of an industrial vehicle. The gateway transmits CAN data wirelessly to a handheld tablet, providing the operator the required control and visibility of the continuing process. The device is transparent regarding the transmitted CAN data. Consequently, it suits any CAN-Bus-based higher-layer protocol, including CANopen. One possible application is to create mobile automation islands in a manufacturing process. The gateway will bridge them to the CANopen line wirelessly.
On the CAN Bus side, the device supports bit-rates from 10 kbit/s to 1 Mbit/s. In addition, up to 28 customizable CAN Bus receive pass-through filters are available. A web-based device configuration is supported via a wireless link or LAN. A CLI (Command-Line Interface) is available for configuration and diagnostics tasks. The gateway package comes with a connector, communication processor, and integrated antenna in the same unit rendering an industrial IP66/IP67 protection class.
ESP32 WiFi, Bluetooth Classic, BLE, CAN Bus Module
The ESP32 board comes with an onboard ESP32 WROOM-32 WiFi, Bluetooth Classic, BLE Module, and a CAN Bus port with a transceiver. Also, onboard is an RGB LED, IO pins on a 0.1" pad.
Programming is accomplished through the popular Arduino IDE connected to the USB-to-Serial converter with USB-C connector, automatic bootloader, and reset.
The ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated WiFi and dual-mode Bluetooth. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in dual-core and single-core variations and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules.
