Datasheet

connectBlue release an easy-to-use Bluetooth dual-mode device, the RBS421s, that supports both Classic Bluetooth and Bluetooth low energy and can be used as a Bluetooth Smart Ready client for any host. The robust and water proof Rugged Bluetooth Serial Port Adapter provides a plug-and-play solution to replace conventional serial cables up to 300 meters.

Supporting both Classic Bluetooth v2.1+EDR and Bluetooth low energy v4.0, the RBS421s is a Bluetooth dual-mode device commonly referred to as a Bluetooth Smart Ready device. Connecting to any Bluetooth low energy device, such as a sensor, the RBS421s can access the device’s standard services or other implemented custom services. Based on the Generic Attribute Profile, these Bluetooth low energy v4.0 services stipulate what type of task a Bluetooth device is to perform; for example, a Battery Service or an Automation I/O Service. The RBS421s can also be used in applications where a smart phone, tablet or laptop is to connect to a serial device, such as a Programmable Logic Controller.

Compliant with EMC, Safety and Medical standards, the Bluetooth qualified RBS421s replaces conventional serial cables up to 300 meters and is radio type approved for USA (FCC Part 15), Europe (ETSI R&TTE), Japan (MIC - formerly TELEC) and Canada (IC RSS). The robust and water proof RBS421s also features embedded Classic Bluetooth stack (SPP, DUN and PAN profiles), Bluetooth low energy stack with connectBlue Low Energy Serial Port Service, serial RS232/422/485 interface, and support for 7 slaves connected at the same time.

The Rugged Bluetooth Serial Port Adapter also incorporates sophisticated technical features for enhanced performance including Wireless Multidrop that allows up to seven devices to communicate simultaneously, Extended Data Mode for individual control of the channel data, and easy configuration by AT commands and configuration over Bluetooth technology.

Rolf Nilsson, CEO of connectBlue, commented: “What this means is that since the new RBS421s is dual-mode it can easily read periodic real-time data from small sensors via Bluetooth low energy and simultaneously use Classic Bluetooth for higher throughput connectivity with other devices. This feature gives you the option to choose the best Bluetooth technology for any particular situation and this feature is also true for our Bluetooth Dual-mode Serial Port Module OBS421.”
