I mean how to fetch the result from scanning completion? 案例Gapm_scan_active： 案例GAPM_SCAN_PASSIVE： { EXECUTE_CALLBACK_VOID(app_on_scanning_completed); }

Your question is a bit vague; perhaps you could explain what you mean by "fetch the result..". What result?
thanks for the reply. after scanning, I want to get a list of devices which are found, furthermore , get the device name, rssi, address etc. 顺便说一下，我在gapm_adv_report_ind中设置了一个断点，但没有看到它被达到。
把你在gapm_adv_report_ind_断点handler() in the app_task.c file and you will be able to extract the members of the adv_report struct. If you still dont get an indication you can take the DSPS host implementation (make the changes you require) and place a break point at the same function, just to make sure that you successfully configured your host application.
actually, I have placed a breakpoint at the gapm_adv_report_ind_handler() in the app_task.c file, but it wasn't reached. by the way, I am using the latest sdk5, could you please point me to "DSPS host implementation" ( the folder path), just make sure we are talking the same thing.
I downloaded dsps, the difference is that I am using latest sd5, and **msg->mode = GAP_OBSERVER_MODE** mode, I didn't see the break point was reached. PLEASE help.
I also changed role from GAP_OBSERVER_SCA to GAP_CENTRAL_MST and backwards, but still not work. please help, it has taken me days, please help. static const结构gapm_configuration user_gapm_conf = { //.role = GAP_OBSERVER_SCA, .role = GAP_CENTRAL_MST, .irk = {0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00}, /// Device Appearance (0x0000 - Unknown appearance) //Fill in according tohttps://developer.bluetooth.org/gatt/characteristics/Pages/Characteristi... .appearance = 0, .appearance_write_perm = GAPM_WRITE_DISABLE, .name_write_perm = GAPM_WRITE_DISABLE, /// maximal mtu. .max_mtu = 23,

SDK 3中的dsp实现,没有implementation of a scanner in the SDK 5, i ve changed the app_scanning() function to operate under GAP_OBSEREVER_MODE and i was able to catch the advertising indication. Can you please place your breakpoint in the gapm_adv_report_ind_handler() at the if statement and check again. Also please try to disable duplicate packets filtering to check if this gives you any trouble. About the acting as scanner besides setting your scanning parameters, have you set the configuration (role) of your device to act as a Central ? If you cant catch the advertise indication with the DSPS application maybe something is wrong with the advertising. Please try to run the a simple peripheral application and catch the advertising string with the dsps host application.
This is what i ve tested with the SDK5 template:
1) Go to user_config.h and change the .role to GAP_OBSERVER_SCA
2) In the user_callback_config change the default on_config_complete function with a custom function that will start scanning.
3) Take the scanning function directly from dsps application.
by the way,i can get advertise message by using sniffer tool,so it shouldnot be advertise side problem, i will check the snippet tool,happy weekend and thanks
The window indicates how long the scanner will scan and it must less than the interval (how often your device will scan), if you set your window larger than your interval (interval 10, window 50 or 500) wont get anything. The interval is your scan window plus the time that your device will stay idle between scanning different channels.

嗨achao，
SDK 3中的dsp实现,没有implementation of a scanner in the SDK 5, i ve changed the app_scanning() function to operate under GAP_OBSEREVER_MODE and i was able to catch the advertising indication. Can you please place your breakpoint in the gapm_adv_report_ind_handler() at the if statement and check again. Also please try to disable duplicate packets filtering to check if this gives you any trouble. About the acting as scanner besides setting your scanning parameters, have you set the configuration (role) of your device to act as a Central ? If you cant catch the advertise indication with the DSPS application maybe something is wrong with the advertising. Please try to run the a simple peripheral application and catch the advertising string with the dsps host application.
This is what i ve tested with the SDK5 template:
1) Go to user_config.h and change the .role to GAP_OBSERVER_SCA
2) In the user_callback_config change the default on_config_complete function with a custom function that will start scanning.
3) Take the scanning function directly from dsps application.
4）我能够抓住广告迹象
您还可以使用Smart Spippets工具检查您的应用程序是否扫描。

thanks,can you email me your codes?

谢谢，最后，得到它的工作.
还有一个问题：
如果我改变了“msg->窗口= 5;”（设置为5，工作）到“msg->窗口= 50;”或者“msg-> window = 500”，它没有捕获adv指示，但立即调用user_scanning_completed（在用户回调文件中定义），为什么？窗口在这里是什么意思？
app_easy_timer(300, scan_cb);
struct gapm_start_scan_cmd * msg =（struct gapm_start_scan_cmd *）ke_msg_alloc（gapm_start_scan_cmd，task_gapm，task_app，gapm_start_scan_cmd）;
// Maximal peer connection
msg->mode = GAP_OBSERVER_MODE;
msg->op.code = GAPM_SCAN_PASSIVE;
msg->op.addr_src = GAPM_PUBLIC_ADDR;
//msg->filter_duplic = SCAN_FILT_DUPLIC_EN;
msg->filter_duplic = SCAN_FILT_DUPLIC_DIS;
msg->interval = 10;
msg->window = 5;
ke_msg_send(msg);
Hi achao1104,
The window indicates how long the scanner will scan and it must less than the interval (how often your device will scan), if you set your window larger than your interval (interval 10, window 50 or 500) wont get anything. The interval is your scan window plus the time that your device will stay idle between scanning different channels.
