For more information about firmware version 1.33, please see the Release Notes.

The RN4020 is a fully-certified, Bluetooth Version 4.1 low energy module for designers who want to easily add low power wireless capability to their products.  The small form factor, surface mount module has the complete Bluetooth stack on-board and is controlled via simple ASCII commands over the UART interface.  The RN4020 also includes all Bluetooth SIG profiles, as well as MLDP (Microchip Low-energy Data Profile) for custom data.  Developers can utilize the scripting feature to enable standalone operation without a host MCU or Processor.  The RN4020 can be remote controlled by another module over a secure connection and can be updated via the UART interface or over-the-air.
   
The RN4020 has a built-in high performance PCB antenna optimally tuned for long range, typically over 100 meters.  The compact size, 11.5 x 19.5 x 2.5mm, enables ease of integration in size-constrained applications.  The RN4020 can be used with any low cost microcontroller for intelligent Bluetooth Low Energy applications.  The RN4020 is fully-certified, has the complete Bluetooth stack on-board the module, and is controlled via a simple ASCII UART interface, making it a true drop-in solution that is easy to use, and easy to prototype, greatly speeding time to market.
