Hi Dialog,
I am trying to define my function for the scanning the package over the air, I have checked the document and made my function as the following. My question, where and how should I degine my White List for the scanning?
void scanner(void)
{
struct gapm_start_scan_cmd * cmd = ke_msg_alloc（gapm_start_scan_cmd，
task_gapm，task_app，
gapm_start_scan_cmd);
cmd->op.code = GAPM_SCAN_PASSIVE;
cmd->interval = 4000; //10s
cmd->window = 4000; //10s
cmd->mode = GAP_GEN_DISCOVERY;
cmd-> filt_policy = scan_allow_adv_wlst;
cmd->filter_duplic = SCAN_FILT_DUPLIC_DIS;
ke_msg_send(cmd);
}
设备：
Hi liuluan002,
Please have a look at the RW-BLE-GAP-IS for the GAPM_WHITE_LIST_MGT_CMD this way you can manage the devices you have in your with list. You can use something like the following snippet
void manage_white_list(void)
{
uint8_t white_addr[6] = {0x01, 0x00, 0x00, 0xCA, 0xEA, 0x80};
struct gapm_white_list_mgt_cmd * cmd = ke_msg_alloc_dyn（gapm_white_list_mgt_cmd，
TASK_GAPM,
TASK_APP,
gapm_white_list_mgt_cmd,
sizeof(struct gap_bdaddr));
cmd->操作= gapm_add_dev_in_wlist;
cmd->nb = 1;
memcpy((void *) &cmd->devices[0].addr, (void *)white_addr, BD_ADDR_LEN);
ke_msg_send(cmd);
}
谢谢mt_dialog.
thank you. One more questions.
When I try to make the broadcasting from the following functions: by broadcasting different package into the air each 10ms. Is it possible to make the broadcasting different package faster than 10ms? Is there any influence to make the broadcasting process fails, if I make it broadcasting out quite quickly? Is it a problem for the receiving side scan to get it?
void set_adv_func(struct gapm_start_advertise_cmd *cmd,uint8_t *data, uint8_t len)
{
if ( len > 26 )
{
len = 26;
}
cmd-> op.code = gapm_adv_undirect;
cmd->op.addr_src = GAPM_PUBLIC_ADDR;
cmd->intv_min = 16; // 32*0.625 =20ms;
cmd-> intv_max = 16;//
cmd->channel_map = 0x01;//channel 37
cmd->info.host.mode = GAP_GEN_DISCOVERABLE; //General Discoverable Mode
// / * ----------------------------------------------------------------------------------
//*Set the Advertising Data and the Scan Response Data
// * -------------------------------------------------------------------- * /
cmd->info.host.adv_data_len = APP_ADV_DATA_MAX_SIZE;
cmd-> info.host.scan_rsp_data_len = 0;//没有响应扫描
if（（数据！= null）&&（len> 0））
{
memcpy (cmd - > info.host.adv_data +2, data, len);
cmd->info.host.adv_data_len = len+2;
cmd->info.host.adv_data[0] = len + 1;
}
else
{
#if debug_log2.
printf_string("\r\nEmpty input so load Data1:");
UART2_INIT（UART_BAUDRATE_115K2,3）;
#endif
memcpy (cmd - > info.host.adv_data +2, data, 26);
cmd-> info.host.adv_data_len = len + 2;
cmd->info.host.adv_data[0] = len + 1;
}
//update the data for broadcasting each 10*1ms
ke_timer_set(APP_DYNAMIC_ADV_DATA, TASK_APP, 1);
返回;
}
嗨对话框，
我用以下代码测试了白色列表
In the app_task.c, I have write the following:
void app_scan（void）
{
manage_white_list();
struct gapm_start_scan_cmd * cmd = ke_msg_alloc（gapm_start_scan_cmd，
task_gapm，task_app，
gapm_start_scan_cmd);
cmd->op.code = GAPM_SCAN_PASSIVE;
cmd->间隔= 4800;
cmd->窗口= 4800;
cmd->mode = GAP_GEN_DISCOVERY;
cmd-> filt_policy = scan_allow_adv_wlst，
cmd->filter_duplic = SCAN_FILT_DUPLIC_DIS;
//Send the message
ke_msg_send(cmd);
}
When I try to call the app_scan, the first time it works, the second time it does not works, the third time works.... I have found it only works for the odd times. For the even times, it does not works. Could you please help?
Hi liuluan002,
What do you mean when you say that "it doesn't work", it retruns any device advertising at the moment or it doesn't return anything ? I am issuing scans via external interrupts using a button using your scan configuration, the device seems to be returning the device in the white list in every press (please check it by using a break point in the advertising indication user_on_adv_report_ind() function). Also i would advice you, not to place the addition of the a new device in the scan request function. Every time you are issuing a scan i suppose that you are adding the same device (i am not aware if this can cause you any trouble). Please have a look at the keyboard reference design in the app_white_list.c file, it uses the white list feature, perhaps you will find it usefull.
谢谢mt_dialog.
Hi Dialog,
我的意思是“没有工作”是扫描不返回任何东西。如果我在每次运行时将函数“manage_white_list（）”放入我的“app_scan（）”，第一次扫描正常，计时器重置后的第二次“ke_timer_set（app_switch_role_timer，task_app，250）;和ke_timer_set（app_switch_role_timer，task_app，20）;“似乎扫描没有返回任何东西。此外，这保持继续返回下次用于扫描的工作，下次下一次没有用于扫描（这种现象继续持续）。
如果我只使用“manage_white_list()函数“for once, the next time after I GAPM_RESET by the timer"ke_timer_set(APP_SWITCH_ROLE_TIMER, TASK_APP, 250);"and reload the "app_scan()" function, it will return back nothing. The next, when I do the GAPM_RESET again, then use the "app_scan" still return back nothing.
这是我的代码的一些部分
In the app_task.c:
//device configuration updated
CASE GAPM_SET_DEV_CONFIG：
{
if（param-> status！= gap_err_no_error）
{
assert_err（0）;// 意外的错误
}
else
{
if( 0 == current_role)
{
//Advertisement
EXECUTE_CALLBACK_VOID(app_on_set_dev_config_complete);
}
else
{
//扫描
app_scan（）;
}
if( 0 == current_role)
{
ke_timer_set(APP_SWITCH_ROLE_TIMER, TASK_APP, 20);
}
if( 1 == current_role)
{
ke_timer_set(APP_SWITCH_ROLE_TIMER, TASK_APP, 250);
}
}
}
break;
void manage_white_list(void)

sizeof(struct gap_bdaddr));
cmd->操作= gapm_add_dev_in_wlist;
cmd->nb = 1;
memcpy((void *) &cmd->devices[0].addr, (void *)white_addr, BD_ADDR_LEN);
ke_msg_send(cmd);
}
volatile uint8_t white_flag;
void app_scan（void）
{

{
manage_white_list();
white_flag = 5;
}
struct gapm_start_scan_cmd * cmd = ke_msg_alloc（gapm_start_scan_cmd，

cmd-> filt_policy = scan_allow_adv_wlst，
cmd->filter_duplic = SCAN_FILT_DUPLIC_DIS;

}
In app.c, we have:

Hi liuluan002,
由于您在角色之间交替，我不确定这是由白色列表引起的东西，请删除白色列表管理并尝试扫描并返回您可以找到的BD地址。当您在第二次尝试时，您无法找到您的设备的任何广告，您根本可以扫描吗？我的代码意味着您的设备配置为每秒钟和外设无法扫描的外设（如果）user_gapm_conf.role是A.GAP_PERIPHERAL_SLV).
谢谢mt_dialog.
Hi Dialog,
I did not use the GAP_PERIPHERAL_SLV, when it is scanning, My role switching function is written as the following:
volatile uint8_t current_role = 1; //0±íʾÔÚ×ö¹ã²¥£¬1±íʾÔÚ×öɨÃè
static struct gapm_set_dev_config_cmd* app_easy_gap_dev_config_create_msg(void)
{
//Allocate a message for GAP
if（set_dev_config_cmd == null）
{
struct gapm_set_dev_config_cmd* cmd;
cmd = app_gapm_configure_msg_create();
set_dev_config_cmd = cmd;
if(USER_CONFIG)
{
cmd->操作= gapm_set_dev_config;
if( 1 == current_role ){
cmd->角色= user_gapm_conf.role;
current_role = 0;
}别的
{
cmd->角色= gap_central_mst;
current_role = 1;
}
cmd->appearance = user_gapm_conf.appearance;
cmd->appearance_write_perm = user_gapm_conf.appearance_write_perm;
cmd->name_write_perm = user_gapm_conf.name_write_perm;
cmd->max_mtu = user_gapm_conf.max_mtu;
cmd-> con_intv_min = user_gapm_conf.con_intv_min;
cmd->con_intv_max = user_gapm_conf.con_intv_max;
cmd->con_latency = user_gapm_conf.con_latency;
cmd->superv_to = user_gapm_conf.superv_to;
cmd->标志= user_gapm_conf.flags;
memcpy(cmd->irk.key,user_gapm_conf.irk,KEY_LEN);
}
else
memcpy（（void *）cmd，（void *）和default_set_dev_config，sizeof（struct gapm_set_dev_config_cmd））;
}
return (set_dev_config_cmd);
}
现在我试图改变只运行扫描的代码，但有时它在扫描期间无法获得任何东西。然而，大多数时间都可以从扫描中获得结果。
CASE GAPM_SET_DEV_CONFIG：
{
if（param-> status！= gap_err_no_error）
{
assert_err（0）;// 意外的错误
}
else
{
if( 0 == current_role)
{
EXECUTE_CALLBACK_VOID(app_on_set_dev_config_complete);
}
else
{
app_scan（）;
position11++;
}
if( 0 == current_role)
{
ke_timer_set（app_switch_role_timer，task_app，0）;
}
if( 1 == current_role)
{
ke_timer_set(APP_SWITCH_ROLE_TIMER, TASK_APP, 250);
}
}
}
break;

Hi Dialog,
您有一个例子是否在白色列表中添加了3个地址？
How to do it?
Thank you
Hi liuluan002,
最小间隔根据广告BLE spec is 20ms, the stack wont let you advertise in 10ms. I assume that you stop the advertsing using the timer and you issue an app_adv_start when the timer elapses. That has nothing to do with the specified interval. If you want to trasmit faster (you are out of the BLE spec so we aren't able to know what problems might occur) you could wait for a BLE advertising event to finish, stop the advertising, change the string, and start once more. You can check how this is done (track the end of an advertising event) by checking the beacon reference design in the app_asynch_trm() function.
谢谢mt_dialog.
此外，当我尝试使用主动扫描测试时，系统将在扫描一段时间后重新启动。它也弹出一些全部零的包。
void app_scan（void）

cmd->mode = GAP_GEN_DISCOVERY;
cmd-> filt_policy = scan_allow_adv_wlst，

Hi liuluan002,
From your initial code i can see that whenever you issue a GAPM_RESET_CMD you are changing roles between the user_gapm_conf.role (what is the value of this if not GAP_PERIPHERAL_SLV ? ) and GAP_CENTRAL_MST depending on the current_role variable that changes to the opposite role every time you have a reset. You mentioned that the white list works in every odd number and you get some data back, in order to narrow down the problem please dont use the white list but try to scan all the available devices that are advertising at the moment in order to make sure that you are scanning indeed.
问题可能是您的UART打印（如果您使用Arch_printf（）函数以打印数据），则在Arch_Main.c文件中的Schedule_While_ble_On（）中尝试将代码放在片段中并删除如果（app_async_trm（））中断;和ARCH_PRINTF_PROCESS（）;
if (app_asynch_trm())
{
继续;
}
else
{
arch_printf_process();
break;
}
Regarding your issue that sometimes you dont get any advertising, are you certain that your device is advertising ? and also i ve noticed that your scanning window is as long as your interval, that means that you listen to only one advertising channel for a quite long period, try to reduce your window and your interval in order to listen to all three channels of advertising frequently since there might be confilicts at that particular channel at the time you are scanning. Also as i allready mention this might occur due to UART printing, please try to catch the advertising indications using break points instead of UART printing in order to be sure. Finally perhaps at the time you are performing the scanning there is two much air activity and no advertising can reach your receiver intact so you dont get any indications.
About the zeros you are getting, are data from the scan request you are sending to the peripheral, those are the scan response data of your peripheral device.
谢谢mt_dialog.
我删除了白色列表，并开始扫描和检查而无需在扫描期内丢失，似乎它有效。问题我猜这是您为White List提供的功能可能导致问题。
Do you means 14583 may go into the mode not GAP_PERIPHERAL_SLV, and either not GAP_CENTRAL_MST, which do you means may triggers it can not scan anything from the broadcasting package?
If I use white list, it seems it works for the 70% of the period, some periods can not scan anything.(now it is not even and odd problem)
我今天测试了以下代码，似乎没有有助于改善扫描中丢失的包。
if (app_asynch_trm())
{
继续;
}
else
{
arch_printf_process();
break;
}
Is it possible that you can help us to check part of the code please? May I get your email and send it to you?
你的意思是gap_peripherwal_slv
Hi liuluan002,
In your device you are changing roles, from GAP_CENTRAL_MST to something else defined in your configuration file, what is the other role that you instruct your device to turn into after it gets the reset, what is the other role user_gapm_conf.role in this variable ?
if(USER_CONFIG)
{
cmd->操作= gapm_set_dev_config;
if( 1 == current_role ){
cmd->角色= user_gapm_conf.role;
current_role = 0;
}别的
{
cmd->角色= gap_central_mst;
current_role = 1;
}
Also regarding the white list, there is an implementation of the white list in the keyboard reference design in the app_white_list.c in the send_white_list_mgt_cmd() function, you can have a look at this.
谢谢mt_dialog.
我认为它是Gap_peripheral_slv，我在user_config.h中找到了以下内容。

Hi liuluan002,
To be honest i haven't understand what you are trying to do, you are performing role switching between to roles the one is central and the other is a peripheral, the peripheral cant execute the scanning procedure. So since you are only scanning why you need this extra code of the role switching. Even with the role switching in an attemp to replicate your problem i ve made a device that issues a role switch on a button press, the scanning procedure included the white list didn't show any kind of manfunctions and always returned the proper device. Please try to make a simple scanner with no role switching based on the DSPS host application and then you can apply the white list and test it.
谢谢mt_dialog.
Hi,
我正在执行角色切换是因为我想制作一个用于扩展广播包的距离的转发器。当我从扫描中获取广告包时，我只需通过向下的角色交换机重复我。
