Overview
The SPBTLE-RFTR is a Bluetooth Low Energy (BLE) module developed by STMicroelectronics. It is compliant with Bluetooth v4.1 and supports both master and slave modes, allowing for multiple roles to be supported simultaneously. This module is designed for low-power applications and is integrated into various development boards, such as the Nucleo series. However, it is important to note that the SPBTLE-RFTR has replaced the SPBTLE-RF, with the main difference being the packaging format (Tape & Reel for SPBTLE-RFTR).
