Over the Air Download (OAD)¶
This section serves as a guide to the Texas Instruments Over-the-Air Download (OAD) ecosystem including the custom profile specification, application architecture, drivers, and middleware. OAD is a device firmware upgrade method that allows the firmware image running on a device to be updated over the air using a Bluetooth low energy connection while providing power loss protection.
Updating the device firmware over serial (UART or SPI) connection from a host MCU using the CC26xx embedded ROM Serial Bootloader (SBL) is covered in application note CC2538/CC26xx Bootloader Interface (SWRA466).
