Looking for an easy way to add low power wireless capability to your project? Look no further than the RN4020. This compact Bluetooth Version 4.1 low energy module features surface mount module and comes with the complete Bluetooth stack on-board. Controlled via simple ASCII commands over the UART interface, this device includes all Bluetooth SIG profiles along with MLDP (Microchip Low-energy Data Profile) for custom data. You can even move to a standalone operation without a host MCU or Processor by simply applying the scripting feature. Better still, the RN4020 can be remotely controlled by another module across a secure connection, and you can update it via the UART interface or over-the-air.
