connectBlue is expanding its Bluetooth module range with the Bluetooth Serial Port Module OBS421 which is designed for Bluetooth v4.0 featuring Bluetooth low energy technology. The ready-to-embed OBS421 module is a mid-range module tailored for the especially tough demands of industrial and medical applications.

The new Bluetooth Serial Port Module OBS421 replaces the Bluetooth Serial Port Module OEMSPA331. Compared to the former device, the OBS421 offers greater throughput and higher receiver sensitivity. The module has a small form factor, a low build height, and initially supports Bluetooth 2.1+EDR. Since the hardware supports Bluetooth v4.0, the OBS421 can be upgraded with Bluetooth low energy technology through an upcoming firmware upgrade.

“Besides supporting the Bluetooth low energy feature – the very latest in Bluetooth technology – the new OBS421 module offers several upgrade advantages,” says Rolf Nilsson, CEO of connectBlue. “For instance, customers using short range modules with external antennas would gain cost savings and design improvements when upgrading to the OBS421 which has an internal antenna. In addition, the upgrade would also give these customers the opportunity to communicate with up to seven slaves simultaneously which typically would only be achieved through the use of more complex and higher cost modules.”

The new Bluetooth Serial Port Module OBS421 provides a mid-range (0-300 meters) wireless transparent serial link using an embedded Bluetooth stack with Bluetooth profiles GAP, SPP, DUN, and PAN. Key features include high throughput, low latency, high receiver sensitivity, Android support, and high speed UART. The OBS421 also supports Apple iOS connectivity with firmware for use by Apple MFi licensees.

Besides the above mentioned features, the OBS421 complies with all industrial and medical requirements including full radio type approval (FCC, IC and R&TTE); EMC, Safety and Medical standards; and Bluetooth qualification. The module 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, easy configuration by AT commands and configuration over Bluetooth technology.
