Legacy OAD Versions

Prior to the BLE-Stack v2.2.0 release, there were three versions of OAD supported by the SDK:
1. Off chip OAD with preserved page 0 using BIM
2. Off chip OAD without preserved page 0 using Baseloader
3. On chip OAD using BIM
In BLE-Stack SDK versions prior to 2.2.0, the SensorTag embedded project supported the baseloader
(Method 2) from above. In conjunction with the embedded project, the SensorTag mobile applications
(iOS, Android) only supported the baseloader method (Method 2). This method has been discontinued*
as of BLE-Stack v2.2.0, all projects (including the SensorTag) have now standardized on Methods 1 and 3.
This guide (and its previous versions) will describe the BIM based on On-chip and Off-chip methods
(Method 1 and Method 3 above).
*The baseloader method has been discontinued because there is a risk where a device may become
bricked (require wired JTAG access to recover) if a power loss is experienced while updating page 0*
1.3

Supported OAD Downloaders

As mentioned above, the SensorTag mobile applications supported the baseloader method prior to BLE-
Stack v2.2.0. These applications are in the process of being updated to support BIM based methods. For
the best out of box experience, TI recommends that customers use BLE Device Monitor v2.1.5 or later as
their OAD downloader, as it supports all OAD methods mentioned above.
