问题描述

我有一个自定义的GATT服务器，在Linux上使用BlueZ 4.101作为插件工作.我现在正在尝试设置自定义扫描响应广告数据.我在iOS上使用LightBlue调试我的GATT服务器和广告参数.我尝试了以下代码，LightBlue可以看到广告有效负载和设备名称，但看不到扫描响应"数据.如何使用BlueZ设置自定义扫描响应数据?谢谢.

I have a custom GATT Server working as a plugin using BlueZ 4.101 on Linux. I am now trying to set custom Scan Response advertising data. I am using LightBlue on iOS to debug my GATT Server and advertising parameters. I tried the following code, and LightBlue can see the Advertising Payload and Device Name, but not the Scan Response data. How do I set custom Scan Response data with BlueZ? Thanks.

# BLE Name
echo "<GATT SERVER> Setting BLE Advertising Name..."
btmgmt -i $BLUETOOTH_DEVICE name "My-Test-Device"

echo "<GATT SERVER> Starting BLE Advertising..."
hciconfig $BLUETOOTH_DEVICE leadv

# Adv Packet
echo "<GATT SERVER> Setting BLE Advertising Packets..."

推荐答案

您用于设置发现响应的命令没有任何意义.这是一个例子:

Your command to set discovery response does not make any sense. Here is an exemple :

hcitool -i hci0 cmd 0x08 0x0009 14 13 09 74 68 65 20 70 69

  hcitool -i hci0 cmd 0x08 0x0009 : set discovery response
  14 : total payload length
  13 : info payload length
  09 : info type == name
  74 68 65 20 70 69 : info payload => the name in ascii. here "the pi"

请注意，如果您的设备不可连接，则此操作将无效.

Please note that this won't work if you device is not connectable.
