The robust and water proof RBS421s provides a plug-and-play solution to replace conventional serial cables up to 300 meters.

Since the Rugged Bluetooth Serial Port Adapter RBS421s supports Classic Bluetooth v2.1+EDR and Bluetooth low energy v4.0, it is a Bluetooth dual-mode device commonly referred to as a Bluetooth Smart Ready device. The RBS421s can connect to any Bluetooth low energy device, such as a sensor, to get access the device’s standard services or other implemented custom services. These Bluetooth low energy v4.0 services are based on the Generic Attribute Profile (GATT) and stipulate what type of task a Bluetooth device is to perform; for instance, 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, for example a Programmable Logic Controller (PLC).


The robust and water proof Rugged Bluetooth Serial Port Adapter 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 RBS421s is also compliant with EMC, Safety and Medical standards, and Bluetooth qualified. Further, the Serial Port Adapter has 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.

Besides the above mentioned features, the Rugged Bluetooth Serial Port Adapter RBS421s 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.
