Hello All, Trying to find out if there are build options someplace in the Standard SDK to compile a BLE beacon bit the RTL8720dn rtlduino , BW16 module ? There none that I see in the ‘examples’ directory. Am very illetierate on this,and if there are some examples would like to try and learn a little more on this. Thanks ---

the BLE beacon example can be enabled by using make `menuconfig -> config BT -> BT beacon`. the specific example files are located at `\component\common\bluetooth\realtek\sdk\example` ---

Hi wyy, As soon as i enabled the BLE-\> Beacon and saved as alternate file. Then done a make all in the project\_hp directory am now getting the following error: ```auto mbd_sdk/ambd_sdk/project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/asdk/../../../../../component/soc/realtek/amebad/fwlib/usrcfg/rtl8721dhp_intfcfg.c:46:2: error: #error "You should allocate flash sectors to for FTL physical map as following, then set FTL_MEM_CUSTEM to 1. For more information, Please refer to Application Note, FTL chapter. " #error "You should allocate flash sectors to for FTL physical map as following, then set FTL_MEM_CUSTEM to 1. For more information, Please refer to Application Note, FTL chapter. " ``` I did look in the application notes PDF at the FTL chapter but dont really know what to do,to circumvent the error that is showing here? Thank You ---

Ok, Got through the previous error.and done as recommended in the Appication Notes PDF. Now am getting the following error( after enabling BLE-\> beacon.) ```auto /home/brcisna/MyPrograms/ambd_sdk/ambd_sdk/project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/asdk/../../../../../component/common/api/at_cmd/atcmd_bt.c:977: undefined reference to `bt_beacon_app_init' /home/brcisna/MyPrograms/ambd_sdk/ambd_sdk/project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/asdk/../../../../../component/common/api/at_cmd/atcmd_bt.c:985: undefined reference to `bt_beacon_app_deinit' collect2: error: ld returned 1 exit status make[1]: *** [Makefile:358: linker_image2_ns] Error 1 make[1]: Leaving directory '/home/brcisna/MyPrograms/ambd_sdk/ambd_sdk/project/realtek_amebaD_va0_example/GCC-RELEASE/project_hp/asdk' make: *** [Makefile:17: all] Error 2 ``` ---

It is my mistake, you are right that the BT beacon example has not been released in the current GitHub version of the SDK. The examples currently available are central, peripheral, scatternet and config. ---

Hi @Cool , Can I check what example are you running and can you screenshot what error etc? Would you mind sharing the code that you are building? Thank you. ---
