用作外围设备时的静态引脚

你好,

I am working on a heart rate sensor application and I have put together an app which is working well. ie, I am able to connect and view HR using any standard android BLE app.
I am using the BASIC development kit as peripheral slave for this purpose.

Now, I want to add some security so that only a user with a pin can connect to the peripheral. I know that this is vulnerable to brute force attack but that is okay.
这些是我对同样的变化。

void app_sec_init_func(void)
{
#if(ble_app_sec)
app_sec_env.auth =(gap_auth_req_mitm_bond);
#endif
}

void app_send_pairing_rsp_func(struct gapc_bond_req_ind *param)
{
struct gapc_bond_cfm * cfm = ke_msg_alloc(gapc_bond_cfm,ke_build_id(task_gapc,app_env.conidx),task_app,gapc_bond_cfm);

cfm->请求= gapc_pairing_rsp;
cfm->接受= true;

// OOB信息
cfm->data.pairing_feat.oob = GAP_OOB_AUTH_DATA_NOT_PRESENT;
//加密密钥大小
cfm->data.pairing_feat.key_size = KEY_LEN;
// IO capabilities
cfm->data.pairing_feat.iocap = GAP_IO_CAP_DISPLAY_ONLY;
//身份验证要求
cfm->data.pairing_feat.auth = GAP_AUTH_REQ_MITM_BOND;
//安全要求
cfm-> data.pairing_feat.sec_req = gap_sec1_auth_pair_enc;
//Initiator key distribution
cfm->data.pairing_feat.ikey_dist = GAP_KDIST_ENCKEY;
//响应者密钥分布
cfm-> data.pairing_feat.rkey_dist = gap_kdist_enckey;

KE_MSG_SEND(CFM);
}
由于CFM-> Data.pairing_feat.iocap = gap_cap_display_only;,Android设备应该弹出键盘时配对时输入引脚。
收到绑定请求时,应调用app_send_tk_exch_func()将设置静态引脚。

Now,the android when I try to pair using android device, the android device just says key mismatch without keyboard popping up. Also, I dont get GAPC_TK_EXCH request gapc_bond_req_ind_handler() for this case.

只要检查到CFM-> Data.pairing_feat.iocap = gap_cap_kb_only时;然后,当配对android设备显示应在外围设备(按预期上输入的随机配对代码时。但是,这不是我需要的。

你能告诉我什么是错的吗?

Thanks in advance.

嗨Ashwin Rao.

嗨Ashwin Rao.

If i understand correctly you would like to connect to your device by using a passkey which will be entered by the keyboard of your host (phone). Well, you can try changing the IO_Capabilities of your host to “Keyboard Only” in order to accomplish something like that. The device’s IO Capabilities should be NoInput/NoOutput since the device isn’t going to have any buttons and the PIN number would be fixed. The “Display capability” you mentioned I don’t think that will force the android device to display the keyboard.

谢谢mt_dialog.

你好,

你好,
谢谢你的回应。

根据
https://developer.bluetooth.org/TechnologyOverview/Pages/LE-Security.aspx
我提到的设置是正确的。

在您的帖子中,您提到的“设备的IO功能应该是noinput / nooutput,因为设备不会有任何按钮,并且PIN数将是固定的。”
But according to the above link, if that is done, then just works authentication mode will be used which is not what I need.

I am reading through this

我正在阅读这篇文章,寻求帮助/提示我如何能够做到这样的事情:

--On the peripheral, press a button, and for the next 2 seconds, broadcast and allow a connection from ANY android device that is scanning (looking for my service's UUID).
--Once that bond is established, turn off braodcasting, and now in the future, allow ONLY that android device to reconnect without the button press.
- 这似乎非常简单,但我找不到关于如何做到这一点的良好建议。
- 我已经在外设工作中拥有其他一切,只想添加它。

我应该在对话中提到你们的人,如果可能的情况,如果可能的情况下,如果可能的情况,您可能会更有帮助,并且可以在论坛中完全回答问题。我在这里读过的大部分帖子都没有得到答复,最终帖子来自对话主持人,他们说的是“我要脱机送你的东西......”我意识到有时候没有容易的答案对于你们所获得的许多问题,但它让我们遇到了一堆死胡同。

Hi klim, thanks for your

嗨Klim,谢谢你的反馈。我同意离线采取东西不是理想的:有时它是必要的(因为问题的长度/复杂性意味着它不能在这里处理),但总体而言,您的情绪是正确的,非常感谢:在线更好。我将有一个团队展望您的要求,我们会反馈。

谢谢&br je_dialog

谢谢je_dialog,我很高兴

谢谢je_dialog,我很高兴that you didn't see this as a negative comment, it was not meant to be. I will keep an eye on this thread and see if you guys have something that will point me in the right direction.

Hi Klim9531, Our initial

Hi Klim9531, Our initial thought is that :

  • DA14580cannot distinguish between iOS or Android. So there has to an App which writes to a custom characteristic to tell it that it is an Android phone.
  • Once the above step is performed, one can retrieve the peer device’s BD address and add it to the white list.

Do you need to distinguish between an android and iOS device ?

这可以从键盘参考设计(剥离)构建。我们有一个关于我们可以分享的白名单的内部注意事项(这表明如何将设备添加到白名单中,有效地将制作已知连接列表,并且仅连接到白名单的那些)。

嗨je_dialog,

嗨je_dialog,

感谢输入,这里有一些澄清:

——客户端设备是否都无所谓Android or iOS (I currently have a fully functioning android app to interface with the device, I intend to built an iOS app soon). The android app scans for advertising devices and if it finds one with my name/service, I begin data transfer. This design is based on the Serial Port Service app.

你的想法。在DA14580中获取设备的蓝牙地址并在DA14580中与我的需求有关。这是我想要的序列:

1. DA14580 is powered on, has never before connected to a peer device (Android or iOS).
2. User presses a button on DA14580 (resets the whitelist, however this list is empty at first power-up).
3.用户启动Android / iOS应用程序,2.5秒内应用程序开始扫描任何BT设备,找到我的命名服务,并开始双向通信(此部分当前正在工作)。
4. DA14580查询Android / IOS设备并获取BD地址,然后在白名单中存储该地址。
5.通信继续,直到DA14580断电。
6.重新启动DA14580后,它现在只允许与白名单中的设备进行通信。
7.如果再次按下DA14580上的按钮,则清除白名单中的Android / IOS设备,DA14580重复上述#2。

如果您可以发布对话框的内部注意事项的链接 - 如何查询设备,然后将其BD地址添加到白名单 - 然后可以帮助我对此进行排序。

我会等你的回复,同时这样做,看看键盘参考设计。

谢谢你的帮助,klim9531
