WRAP THOR 2022-1 Bluetooth Module

The WRAP THORTM 2022-1 is a robust, configurable Bluetooth surface mount module optimized for embedded applications. The surface mount module enables device manufacturers to easily add secure, robust, and globally accepted wireless standards into new or existing applications with reasonable development and manufacturing effort. The Bluetooth surface mount module supports several different mobile integration designs:

  • With a host utilizing Bluetooth as a modem, the module acts autonomously (iWRAPTM ASCII based Interface)
  • With host running an upper layer Bluetooth stack (Host Command Interface, HCI)
  • With I/O lines where the module samples or analyzes the I/O operations autonomously
  • With external Codec via the PCM Interface for audio applications

Key features

  • Surface mount module for embedded applications
  • Bluetooth® 1.1 and 1.2 compliant
  • Class 1, 100-meter range (output power 18 dBm, sensitivity -85dBm)
  • iWRAPTM ASCII based interface for controlling connections and configuring the module (Serial Port Profile, unified Master and Slave)
  • Radio signal strength measurement (RSSI)
  • Seamless Bluetooth® networking with Bluegiga’s WRAP Access ServerTM
  • All Bluetooth Power save modes supported (park, sniff, hold, deep-sleep)
    • Link active min: 7mA, max: 150mA
    • Link active in sniff mode: 1.5mA
    • Link active in park mode: 1.6mA
    • Idle with deep sleep: 1.3mA
  • PIO and SPI interfaces for hardware integration
  • Supports custom applications inside the module
  • Several pre-programmed firmware options and custom firmware production available
  • Full industrial temperature range -40 to +85 Celsius
  • Compact size: 25.6 x 14 x 2.5mm
  • Bluetooth, FCC and CE certified

The WRAP THOR Module is a completely integrated Bluetooth solution. The module facilitates a 100-meter communication range and the line of sight reaches a 200-meter range. The module is available with several different firmware options for data and audio communications. Bluegiga also provides custom firmware production services thus eliminating the need for OEMs to perform any module flashing in the production line. This provides significantly more cost effective production rather than manufacturing based on Bluetooth ICs or standard Bluetooth modules.


  • Cable replacement Between Bluetooth enabled devices
  • Cable replacement for up to 21 Bluetooth devices when using Bluegiga’s WRAP Access Servers as a router
  • Point-of-sales systems (Barcode readers and pay terminals)
  • Telemetry and machine-to-machine interfaces
  • Logistics and transportation systems and fleet management
  • Automotive inspection and measurement systems
  • Medical systems
  • Fitness and sports telemetry
  • PDAs and other portable terminals
  • Industrial PCs and Laptops
  • RS232 Cable Replacers

By using Bluegiga WRAP THOR Modules, Bluegiga world-class Radio Frequency laboratory and Bluetooth support, OEMs ensure that products reach the market cost-effectively in relation to time and resources. Bluegiga develops in-house Bluetooth protocol stacks and module hardware enabling a single point of contact for all Bluetooth-related activities.

Available Firmware / Software for WRAP THOR Modules
