Key features

The OEM SERIAL PORT ADAPTER™ 411 series is a Bluetooth™ module with support for the Serial Port Profile (SPP) for fast and secure transparent serial data transmissions. The module has a small form factor and low build height, and supports the Bluetooth™ 2.1+EDR standard for enhanced data rates (Bluetooth 3.0 prepared via firmware upgrade). Since the Bluetooth stack is embedded in the module it does not require any driver or stack in your host so that you can be up and running in the shortest possible time. It is fully Bluetooth™ qualified and radio type approved for Europe, US and Canada, and has the connectBlue™ standard interface for compatibility over time and radio technologies.

  • Embedded Bluetooth stack (SPP, DUN, PAN)
  • Customer developed applications can be embedded
  • Bluetooth 2.1+EDR
  • Bluetooth 3.0 prepared via firmware upgrade
  • High Speed UART (SPI, I2C, GPIO on request)
  • Very high throughput and low latency
  • Easy configuration by AT commands
  • Radio type approved for Europe, US and Canada
  • Compliant with EMC, Safety and Medical standards
  • connectBlue Low Emission Mode™
  • Wireless Multidrop™ with up to 3 slaves
  • Extended Data Mode™ for separated multipoint data channels
  • Internal or external antenna
  • Industrial and Automotive temperature range -30°C to +85°C
  • Possible to load customer specific configuration in production
  • Individually tested in production
