Overview of the NanoBeacon Mobile App (iOS)

NanoBeacon移動(dòng)應(yīng)用程序(iOS)的概述


There are a few UI and functional differences between the iOS and Android versions of the mobile app due to the limitations and differences between the two operating systems. Still, most of the functionality should be very similar.

由于兩個(gè)操作系統(tǒng)的限制和差異,iOS和Android版本的移動(dòng)應(yīng)用程序之間有一些UI和功能的差異。不過(guò),大部分功能應(yīng)該是非常相似的。


In this tutorial, we will be focusing on the Android app.

在本教程中,我們將專注于Android應(yīng)用程序。


After launching the mobile app, you will be presented with the Scanner view:

啟動(dòng)移動(dòng)應(yīng)用程序后,你將看到掃描器視圖:


e37c6f8a-fa93-11ed-ba01-dac502259ad0.png

The different buttons within this view are:

該視圖中的不同按鈕是:

1.Filters: allow you to filter out and only display devices that match specific filters.

1.過(guò)濾器:允許你過(guò)濾掉,只顯示符合特定過(guò)濾條件的設(shè)備。

2.Clear:clears the list of discovered devices.

2.清除:清除已發(fā)現(xiàn)設(shè)備的列表。

3.Scroll to Top: this allows you to scroll to the top of the list when the number of discovered items extends beyond a single-screen view.

3.滾動(dòng)到頂部:當(dāng)發(fā)現(xiàn)的項(xiàng)目數(shù)量超出單屏視圖時(shí),這允許你滾動(dòng)到列表的頂部。

4.Resume Scanning: the difference between this andRescan is that it does not clear the list of discovered devices.

4.恢復(fù)掃描:這和重新掃描的區(qū)別是,它不會(huì)清除已發(fā)現(xiàn)的設(shè)備的列表。

5.Enable Scrolling: this enables automatic scrolling to always show the latest discovered devices.

5.啟用滾動(dòng):這將啟用自動(dòng)滾動(dòng),以始終顯示最新發(fā)現(xiàn)的設(shè)備。


Filter Options篩選選項(xiàng)


When clicking the Filter options button (three sliders icon), you’re presented with the following view and options:

當(dāng)點(diǎn)擊過(guò)濾選項(xiàng)按鈕(三個(gè)滑塊圖標(biāo))時(shí),你會(huì)看到以下視圖和選項(xiàng):

高級(jí):允許你按廣播數(shù)據(jù)中包含的原始數(shù)據(jù)、公司名稱等進(jìn)行過(guò)濾。在安卓系統(tǒng)上,也可以通過(guò)藍(lán)牙地址進(jìn)行過(guò)濾。

Minimum RSSI: this allows you to filter out devices that are discovered with an RSSI lower than the set value.

最小RSSI:這允許你過(guò)濾掉那些發(fā)現(xiàn)的RSSI低于設(shè)定值的設(shè)備。

Hide unnamed devices: this allows you to hide devices that do not advertise a device name.

隱藏未命名的設(shè)備:這允許你隱藏那些沒(méi)有公布設(shè)備名稱的設(shè)備。

Only show project configuration matches: allows you to only show devices that match the imported IN100 configuration (via scanning the QR code from the NanoBeacon Config Tool app).

只顯示項(xiàng)目配置匹配:允許你只顯示與導(dǎo)入的IN100配置匹配的設(shè)備(通過(guò)掃描NanoBeacon配置工具應(yīng)用程序的QR碼)。

Sort by RSSI: this allows you to sort the list of devices by detected RSSI (starting with the device with the strongest signal).

按RSSI排序: 這允許你按檢測(cè)到的RSSI對(duì)設(shè)備列表進(jìn)行排序(從信號(hào)最強(qiáng)的設(shè)備開(kāi)始)。

類型:允許你只顯示iBeacon、Eddystone UID和Eddystone TLM廣播設(shè)備的任何組合,如下所示:

e38ada16-fa93-11ed-ba01-dac502259ad0.png

The other view (accessible from the bottom section of the app) is the “Configuration” view:

另一個(gè)視圖(可從應(yīng)用程序的底部部分訪問(wèn))是 "配置 "視圖:


e3904af0-fa93-11ed-ba01-dac502259ad0.png

QR Code Scan button allow you to scan the QR Code that the NanoBeacon Config Tool displays to import the IN100 configuration into the mobile app:

QR代碼掃描按鈕允許你掃描NanoBeacon配置工具顯示的QR代碼,將IN100的配置導(dǎo)入移動(dòng)應(yīng)用程序:


e398badc-fa93-11ed-ba01-dac502259ad0.png

Once the configuration is imported into the mobile app, the Configurationview will show the details of the configuration:

一旦配置被導(dǎo)入移動(dòng)應(yīng)用程序,配置視圖將顯示配置的細(xì)節(jié):


e3d61a6c-fa93-11ed-ba01-dac502259ad0.png

To import a new configuration, you can delete the existing one by clicking the Trash icon.()After that, the QR Scan and Import Configuration buttons will become visible on the screen.

要導(dǎo)入一個(gè)新的配置,您可以通過(guò)點(diǎn)擊垃圾桶圖標(biāo)()刪除現(xiàn)有的配置。之后,QR掃描和導(dǎo)入配置按鈕將在屏幕上可見(jiàn)。


Let’s run through a couple of test cases to show how this works!

讓我們通過(guò)幾個(gè)測(cè)試案例來(lái)說(shuō)明這是如何工作的!


Test Case #1: One Advertising Set (iBeacon)

測(cè)試案例#1:一個(gè)廣播集(iBeacon)


Let’s first start by configuring the IN100 in the NanoBeacon Config Tool application on the PC. We will configure it with the following:

讓我們首先在PC上的NanoBeacon配置工具應(yīng)用程序中配置IN100。我們將對(duì)其進(jìn)行如下配置:

One Advertising Set (Continuous)

一個(gè)廣播組(連續(xù))

iBeacon type

iBeacon類型

UUID: E2C56DB5DFFB48D2B060D0F5A71096E0 (randomly generated, you can generate your own UUID here)

UUID: E2C56DB5DFFB48D2B060D0F5A71096E0(隨機(jī)生成,你可以在這里生成你自己的UUID)

Major: 0011

Minor: 2233

Tx Power: -30 dBm

e3f733be-fa93-11ed-ba01-dac502259ad0.png

Make sure your IN100 development and programmer boards are connected together and to the PC. Next, you’ll want to Probe and Connect to the device within NanoBeacon Config Tool. Finally, click the “Run in RAM” button.

確保你的IN100開(kāi)發(fā)板和編程板連接在一起并與電腦連接。接下來(lái),你要在NanoBeacon配置工具中探測(cè)和連接到設(shè)備。最后,點(diǎn)擊 "在RAM中運(yùn)行 "按鈕。


Now, to import the configuration into the mobile app, we will use the new QR Code button available in NanoBeacon Config Tool. To import, navigate to the Configuration view and click the QR Code Scanner (or the Load Configuration) button.

現(xiàn)在,為了將配置導(dǎo)入移動(dòng)應(yīng)用程序,我們將使用NanoBeacon配置工具中的新QR碼按鈕。要導(dǎo)入,導(dǎo)航到配置視圖,點(diǎn)擊QR碼掃描器(或加載配置)按鈕。


Once the configuration is imported, we can see the settings on the screen:

一旦配置被導(dǎo)入,我們就可以看到屏幕上的設(shè)置:

e3ffb2d2-fa93-11ed-ba01-dac502259ad0.png

e412921c-fa93-11ed-ba01-dac502259ad0.png

Now we can switch to the Scanner view to discover our device.

現(xiàn)在我們可以切換到掃描器視圖來(lái)發(fā)現(xiàn)我們的設(shè)備。


In the Scanner view, you’ll likely see many discovered devices, which makes it difficult to find your specific device. One way around that is to look for the device that shows “Configuration Match” in its title:

在掃描器視圖中,你可能會(huì)看到許多已發(fā)現(xiàn)的設(shè)備,這使你很難找到你的特定設(shè)備。解決這個(gè)問(wèn)題的一個(gè)方法是尋找標(biāo)題中顯示 "配置匹配 "的設(shè)備:


e421726e-fa93-11ed-ba01-dac502259ad0.png

But the more straightforward method is to apply the filter “Only show project configuration matches,” which will filter out all other non-matching devices.

但更直接的方法是應(yīng)用過(guò)濾器 "只顯示項(xiàng)目配置匹配",這將過(guò)濾掉所有其他不匹配的設(shè)備。


e432db1c-fa93-11ed-ba01-dac502259ad0.png

Once applied, you’ll get a much better view:

一旦應(yīng)用,你會(huì)得到一個(gè)更好的視圖:


e44d9614-fa93-11ed-ba01-dac502259ad0.png

You can then click on the area (in the red box below) with the device information to view more details:

然后你可以點(diǎn)擊有設(shè)備信息的區(qū)域(在下面的紅框內(nèi)),查看更多細(xì)節(jié):


e4651384-fa93-11ed-ba01-dac502259ad0.png

e4790d76-fa93-11ed-ba01-dac502259ad0.png

For even more details (especially for types other than iBeacon), click on the “View Data” area (in the redbox below):

要想了解更多細(xì)節(jié)(尤其是iBeacon以外的類型),請(qǐng)點(diǎn)擊 "查看數(shù)據(jù) "區(qū)域(在下面的紅框內(nèi)):

e49f517a-fa93-11ed-ba01-dac502259ad0.png

e4c359c6-fa93-11ed-ba01-dac502259ad0.png

Test Case #2: Three Advertising Sets (iBeacon, Eddystone, Custom Data)

測(cè)試案例#2:三個(gè)廣播集(iBeacon、Eddystone、自定義數(shù)據(jù))。

For a more advanced test case, let’s set up three advertising sets:

對(duì)于一個(gè)更高級(jí)的測(cè)試案例,讓我們?cè)O(shè)置三個(gè)廣播集:


1.iBeacon(same as in Test Case #1):

1. iBeacon(與測(cè)試案例#1相同):


e4d9901a-fa93-11ed-ba01-dac502259ad0.png

e4e80064-fa93-11ed-ba01-dac502259ad0.png

2. Eddystone UID

2. Eddystone UID

Modify the Bluetooth Address to something different than what’s set in Advertising Set #1. This is necessary for the mobile app to be able to distinguish between the different advertising sets and display them as separate “devices.” This setting can be found under “Advertising Parameters.”

將藍(lán)牙地址修改為與廣播集#1中的設(shè)置不同的內(nèi)容。這是必要的,以便移動(dòng)應(yīng)用程序能夠區(qū)分不同的廣播集,并將它們顯示為獨(dú)立的 "設(shè)備"。這個(gè)設(shè)置可以在 "廣播參數(shù) "下找到。

Measured Tx Power: -25 dBm

Beacon ID:

① 10-byte Namespace: 00112233445566778899

① 10字節(jié)的名稱空間:00112233445566778899

② 6-byte Instance: 010203040506

② 6字節(jié)的實(shí)例:010203040506


Here are screenshots showing this configuration in NanoBeacon Config Tool:

下面是在NanoBeacon配置工具中顯示此配置的截圖:


e51369d4-fa93-11ed-ba01-dac502259ad0.png

e52f6b16-fa93-11ed-ba01-dac502259ad0.png

3. Custom Type(Triggered)

3. 自定義類型(觸發(fā)式)

Modify the Bluetooth Addressto something different than what’s set in Advertising Set #1. This is necessary for the mobile app to be able to distinguish between the different advertising sets and display them as separate “devices.” This setting can be found under “Advertising Parameters.”

將藍(lán)牙地址修改為與廣播集#1中的設(shè)置不同的內(nèi)容。這是必要的,以便移動(dòng)應(yīng)用程序能夠區(qū)分不同的廣播集,并將它們作為獨(dú)立的 "設(shè)備 "顯示。這個(gè)設(shè)置可以在 "廣播參數(shù) "下找到。

Device Name:“IN100”

Manufacturer Specific Data:

· Company ID: 0505 (InPlay)

· 公司ID: 0505 (InPlay)

· VCC

· VCC

· Internal Temperature

· 內(nèi)部溫度

Triggered Advertising:

觸發(fā)式廣播:

We will be configuring this advertising set as aTriggeredtype.

我們將把這個(gè)廣播集配置成一個(gè)觸發(fā)式的類型。

This will ensure that the advertising packets are only sent when specific conditions are met.

這將確保廣播數(shù)據(jù)包只在滿足特定條件時(shí)發(fā)送。

We will set a High Threshold Trigger to 25 degrees Celsius (Internal Temperature), meaning that when the internal temperature reaches 25 degrees C, this specific advertising set will be triggered and will then show up in the mobile app.

我們將把高閾值觸發(fā)器設(shè)置為25攝氏度(內(nèi)部溫度),這意味著當(dāng)內(nèi)部溫度達(dá)到25攝氏度時(shí),這個(gè)特定的廣播集將被觸發(fā),然后在移動(dòng)應(yīng)用程序中顯示出來(lái)。

To configure this, do the following:

要配置這一點(diǎn),請(qǐng)執(zhí)行以下操作:

Navigate to Global Triggersettings → For Trigger #2, modify select Internal Temperature as the source → set the High Threshold to 2500 (this translates to Threshold * Unit,whereUnit is found in the On-Chip Measurement Units settings).

導(dǎo)航到全局觸發(fā)器設(shè)置→對(duì)于觸發(fā)器#2,修改選擇內(nèi)部溫度作為來(lái)源→將高閾值設(shè)置為2500(這轉(zhuǎn)化為閾值*單位,其中單位在On-Chip MeasurementUnits設(shè)置中找到)。

Next, we need to modify the Advertising Mode to be of the Triggeredtype → under the "Advertising Mode” tab, select “Triggered Advertising,” and under “Sensor Trigger Source,” check the box next to “High Trigger 2”.

接下來(lái),我們需要將廣播模式修改為觸發(fā)式→在 "Advertising Mode"標(biāo)簽下,選擇 "Triggered Advertising",在 "傳感器觸發(fā)源 "下,選中 "高觸發(fā)器2 "旁邊的方框。

Here are screenshots showing these configuration settings within NanoBeacon Config Tool:

下面是在NanoBeacon配置工具中顯示這些配置設(shè)置的屏幕截圖:


e558bb06-fa93-11ed-ba01-dac502259ad0.png

Bluetooth Address (Adv Set #3)

藍(lán)牙地址(Adv Set #3)

e604991c-fa93-11ed-ba01-dac502259ad0.png

Now, we’re ready to run the configuration, import it into the mobile app, and start testing!

現(xiàn)在,我們已經(jīng)準(zhǔn)備好運(yùn)行配置,將其導(dǎo)入到移動(dòng)應(yīng)用程序,并開(kāi)始測(cè)試了!


Once you’ve imported the configuration, you should see the following in your Configuration view:

一旦你導(dǎo)入了配置,你應(yīng)該在你的配置視圖中看到以下內(nèi)容:


e610c796-fa93-11ed-ba01-dac502259ad0.png

e632c65c-fa93-11ed-ba01-dac502259ad0.png

e6438cc6-fa93-11ed-ba01-dac502259ad0.png

e65683f8-fa93-11ed-ba01-dac502259ad0.png

After importing the configuration, we are now ready to start scanning. Let’s switch to the Scannerview.

導(dǎo)入配置后,我們現(xiàn)在準(zhǔn)備開(kāi)始掃描。讓我們切換到掃描器視圖。


We’ll also double-check to make sure that the “Only show project configuration matches” is enabled. The scanner should now show us the two advertising sets (#1 & #2), the iBeacon and Eddystone advertising sets:

我們還將仔細(xì)檢查,以確保 "只顯示項(xiàng)目配置匹配 "被啟用。掃描儀現(xiàn)在應(yīng)該向我們顯示兩個(gè)廣播集(#1和#2),即iBeacon和Eddystone廣播集:


e678a42e-fa93-11ed-ba01-dac502259ad0.png

And we can navigate into the detailed views each of these advertising sets:

而且我們可以瀏覽到這些廣播集的每一個(gè)詳細(xì)視圖:


e68c6ea0-fa93-11ed-ba01-dac502259ad0.png

e68c6ea0-fa93-11ed-ba01-dac502259ad0.png

Notice the third advertising set (which is configured for a Triggered Custom Advertising Data Type) does not show up in the list. This is because the current internal temperature reading is under 25 deg C (at room temperature, around 21 deg C).

注意第三個(gè)廣播集(它被配置為觸發(fā)式自定義廣播數(shù)據(jù)類型)沒(méi)有顯示在列表中。這是因?yàn)楫?dāng)前的內(nèi)部溫度讀數(shù)低于25攝氏度(在室溫下,大約21攝氏度)。


To test out the triggered advertisements, I will apply some heat to the IN100 chipset on the development board (by simply pressing down on it for a few seconds). Once the temperature reaches 25 deg C, we start seeing the third advertising set in the list:

為了測(cè)試觸發(fā)式廣播,我將對(duì)開(kāi)發(fā)板上的IN100芯片組施加一些熱量(通過(guò)簡(jiǎn)單地按下它幾秒鐘)。一旦溫度達(dá)到25攝氏度,我們就開(kāi)始看到列表中的第三個(gè)廣播集:


e6b4d994-fa93-11ed-ba01-dac502259ad0.png

Let’s go into the detailed view to look at the advertising data:

讓我們進(jìn)入詳細(xì)視圖,看看廣播數(shù)據(jù):


e6c522e0-fa93-11ed-ba01-dac502259ad0.png

Notice that the data is actually parsed into a human-readable format and not just hex values! This is the power of using our mobile app in combination with the IN100.

請(qǐng)注意,數(shù)據(jù)實(shí)際上被解析成了人類可讀的格式,而不僅僅是十六進(jìn)制的數(shù)值!這就是使用我們的移動(dòng)應(yīng)用程序與IN100相結(jié)合的力量!


We also see that the Internal Temperature value has crossed the 25 deg C mark confirming the functionality of the Triggered Advertising Mode.

我們還看到,內(nèi)部溫度值已經(jīng)超過(guò)了25攝氏度,證實(shí)了觸發(fā)式廣播模式的功能。
