CC2640: Upgrade Scheme

user5861925

Part Number: CC2640

Hi:

The product I designed USES CC2640. I need to ask you two questions：

（1）What is the existing OTA remote upgrade scheme of CC2640?

（2）Can we download the firmware of Bluetooth MCU through our module, and then upgrade Bluetooth MCU through UART?

Thank you

Hi,

You could either use off-chip OAD (with external flash) or using bootloader and do it from a connected MCU.
