With the increasing popularity and use of single-mode Bluetooth® low energy in automotive, home office, medical and health, sports and fitness, and mobile and PC accessories, Texas Instruments Inc. (TI) released its newest BLE-Stack™ 1.3 software to support continued development and enhancement of Bluetooth low energy. TI’s BLE-Stack 1.3 includes over-the-air firmware downloads (OAD), which enable updates to CC2540/1 firmware to be downloaded from a central device, such as a phone, tablet or PC onto the CC2540/1 system-on-chip (SoC) directly over the RF link.
