Converts the communication between Bluetooth Low Energy(BLE) and RS-485/RS-232 interfaces.
BLE Certification: IFD8540 is Bluetooth 5.0 certified and utilizes 2.4GHz Frequency-hopping Spread Spectrum(FHSS) technology, providing higher transmission speed and wider signal coverage compared with conventional Bluetooth devices. It also adopts AES-CCM 128-bit encryption with higher security level.
BLE Protocol: in addition to common GATT(Generic Attribute Profile) protocol supported by most mobile devices, IFD8540 also offers two kinds of mesh networks to maximize the flexibility in planning an IIoT application.
- SIG Mesh: standard Bluetooth mesh protocol with 15Kbps speed within 50m distance
- GATT: standard Bluetooth protocol which is backward compatible to Bluetooth devices of older versions. It offers up to 2Mbps speed within 50m distance in a point-to-point scenario. Users can use Delta’s Android App (Delta SmartViewer) to perform the functionality available in GATT mode.
Configurable by software or hardware switches for basic parameters such as station ID, BLE group ID, RS-485 baud rate and factory default. Saves configuration time in manufacturing and project commissioning process.
Built in communication indicators (BLE, COM) for easier troubleshooting
Full isolation between communication and power circuits to achieve higher noise immunity
