BLE 5.0 Bolt Adapter
3-Second Engineer Understanding
CAN / RS485 / RS232 → BLE 5.0 wireless bridge (plug-and-play, no firmware change required)
Short Introduction
Industrial BLE 5.0 Bolt Adapter for converting CAN / RS485 / RS232 field bus to Bluetooth wireless, enabling safe, long-distance, cable-free equipment access and control.
Product Description
The BLE 5.0 Bolt Adapter serves as a professional bridge between industrial field buses and Bluetooth wireless networks. It seamlessly converts CAN, RS485, and RS232 bus data to Bluetooth signals and vice versa, acting as an ideal cable replacement solution.
Any standard BLE wireless device can connect to the field bus through this adapter to communicate and interact with bus devices. It is especially suitable for hard-to-reach scenarios such as confined spaces, locked cabinets, or hazardous areas, allowing operators to access and control equipment remotely and safely.
With a rugged enclosure and unique bolt-style design, the adapter can be mounted on any flat surface via a 50mm through hole. Paired with basic protection accessories, it performs reliably in harsh factory automation environments.
The adapter supports three data conversion modes for CAN bus: transparent transmission, transparent with marker, and Modbus RTU conversion. For RS485 and RS232 communication, it provides direct transparent transmission. All parameters can be easily configured via Bluetooth.
