   The current version of the library files are in folder "Google Ref RCU For ATV/Pro_Lib".

2. Download the .a files and copy them into the folder "proj_lib" under the SDK directory "Google_ATV_RCU_Reference_SDK".


========== Instructions for building the SDK ==========

1. cd into the "8271_ble_remote" directory under the SDK root directory "Google_ATV_RCU_Reference_SDK".

2. Type "make" to build the SDK or "make clean" to clean the project.

3. Two bin files will be created in current directory after a successfull build:

3.1. The normal bin file "8271_ble_remote.bin" is the one without encription.

3.2. The file "8271_ble_remote_enc_sign.bin" has been encripted and signed with the default key file "FW_ENC_TEST_KEY".
     This bin file created with the default FW_ENC_TEST_KEY" is just for example purpose and
     is not able to pass the OTA process if encription is enforced.

**********!!!!! Important !!!!!**********

3.3. Vendors need to contact Google for two key files "FW_ENC_KEY" and "priv.pem" and
     copy them into the build directory "8271_ble_remote" to build a right encripted bin file
     "8271_ble_remote_enc_sign.bin" that can pass an OTA process with encription enforced.
