I am using Codeless example for development. I have a function in user_cmd_interpreter that parses UART for 'SN' and will change the local name to something in the form SN123456 for example. The problem I am having is that I have to connect, disconnect and reconnect for the name to update. I have tried calling user_advertise(), but that does not work. I have read that app_easy_gap_update_adv_data() needs to be called. I have searched for that function and I can not find it in the ble_app_barebone files. My two questions are would calling app_easy_gap_update_adv_data() resolve the problem I'm having, and what is the code for app_easy_gap_update_adv_data().

Hi ant777222,
谢谢你的问题在线。只是为了确保无附加版本：DA14580是DA14580所用版本的依氏_v_5.380.5.4.0
>>> “will change the local name to something in the form SN123456 for example”
你的意思是BLE设备名称？如果是，则设备名称被定义为user_device_name宏（ser_config_580.h标题文件），然后将存储到nvds_data_storage结构的nvds_tag_device_name项中。
因此，设备的名称是通过NVDS_TAG_DEVICE_NAME提供的，这是输入广告字符串中的内容。为了改变它，您必须自定义广告功能。und向量_advertise_start_create_msg（）是填充邮件参数的函数，默认默认来自nvds_tag_device_name的名称。您可以在SDK中留下该值空白，使用App_easy_gap_undircated_advertise_get_active（）用所有相应的值分配消息，然后针对包含广告字符串的成员并应用您想要的名称。此外，您必须使用0x09闪存标记名称，以便其他设备知道这是设备的名称。
如果您正在启动新的设计/项目，我们将强烈建议首先以DA14531或DA14585 / 586产品和我们最新的SDK6.0.14开始，因为它更加提高。雷电竞官网登录我们有很多代码示例和改进的文档，还有软件路线图支持。DA14580产品系列和SDK5没有软件路线图支持。

这是我正在使用的版本。我正在更改GAP_AD_TYPE_COMPLETE_NAME和GAP_AD_TYPE_MANU_SPECIFIC_DATA，我在USR_CMD_INTERPRER中拥有以下代码
else if ((input_cmd_type == AT_CMD_SN)&&(cmd_source == CMD_SRC_LOCAL)){
for(uint8_t i = 0; i <= 40; i++){
if（（cmd_rx_buffer [i] =='s'）&&（cmd_rx_buffer [i + 1] =='n'））{
UINT8_T Advertisement_Data []
= {
17，GAP_AD_TYPE_MANU_SPECIFIC_DATA，0x07，0x4D，0xE4，0x00，0x00，0x00，0x00，
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
//蓝牙设备名称
9，gap_ad_type_complete_name，cmd_rx_buffer [i]，cmd_rx_buffer [i + 1]，cmd_rx_buffer [i + 2]，cmd_rx_buffer [i + 3]，
cmd_rx_buffer[i+4],cmd_rx_buffer[i+5],cmd_rx_buffer[i+6],cmd_rx_buffer[i+7] };
for (uint8_t a = 3 ; a < 8; a++) {
广告_data [2 + a] = 0x00;
}
for (uint8_t a = 8; a < 16; a++) {
advertisement_data [2 + a] = cmd_rx_buffer [a + i-8];
}
Memcpy（＆Dodeless_env.service_uuid，＆广告_data [2]，16）;
memcpy（＆dodeless_env.addata，＆广告_data，sizeof（广告_data））;
Codeless_env.addata_len = sizeof（广告_data）;
//无扫描响应数据
Dodeless_env.resp_data_len = 0;
//将无附件设置为可连接。
Dodeless_env.is_connectable = true;
//初始化输入命令索引到零。
console_env.input_cmd_char_index = 0;
//初始化Parser标志
console_env.parser_flag = char_parser_not_active;
user_advertise（）;
send_to_local（cmd_arguments.cmd_buffer）;
break;
}
}
}
这是有效的，但我需要连接一个并断开名称更改的连接。无需连接，我需要名称要更改。
Hi ant777222,
是否有可能澄清以下声明？
> > >”这个工作,但是我需要连接和阀瓣onnect for the name change to take place. I need the name to change without having to connect.”
谢谢，PM_DIALOG.
The command comes in that changes GAP_AD_TYPE_COMPLETE_NAME and GAP_AD_TYPE_MANU_SPECIFIC_DATA. I connect to the BLE device with a phone using lightblue. These fields are unchanged. I disconnect from the BLE device then reconnect and the fields are changed to what the command specified. I need the fields to change immediately without having to connect, disconnect, and reconnect.
Hi ant777222,
You should set up a TIMER in order to update the advertising data. Please have a look at the ble_app_sleepmode example of the SDK and check the app_adv_data_update_timer_used timer. Upon its expiration the adv_data_update_timer_cb() is getting triggered and updates the advertising data.
谢谢，PM_DIALOG.
