Part Number: CC2541. I made device based on CC2541 and ble_sdk_18.104.22.168 (OAD is enabled). Device work fine. OAD feature works fine when i use windows application "BLE device monitor" for upload firmware . I can upload any image( A or B image); Currently i try to implement ability for updating firmware through OAD from android. CC2541. GitHub Gist: instantly share code, notes, and snippets.

The CC2541DK-MINI development kit provides a working reference design for software development of single-mode Bluetooth low energy (BLE) applications based on the Texas Instruments CC2541. The included "keyfob" board operates as a BLE peripheral device, and contains modifiable software that can be tailored towards different applications. An Arduino library for creating custom BLE peripherals with CC2541. It enables you to create more customized BLE Peripheral's providing a 2 way communication. This library interacts with the CC2541 Image (TI "BLE Bridge" Example). The related data transfer algorithm is described here: ![Gitter](http ... 1) TI has not tested or developed the CC2541 SDK or reference code to work in any other IDE except the IAR version noted above. You can use the search function to see if others have been able to port their projects to another IDE. 2) I can't determine from the description presented.
