将 SenseCAP T1000 连接到 Helium
设备配置
在连接到 Helium 之前，您需要在 SenseCAP Mate APP 上配置设备的基本参数，详情请查看开始使用。
- 将平台设置为
Helium，然后复制Device EUI/APP EUI/APP Key。
Helium 控制台配置
Helium 控制台不再对新账户开放。这里保留了如何将 T1000 连接到 Helium 控制台的说明， 供已有账户的用户使用。对于新用户，请参考上面的 ChirpStack LNA 步骤，或根据这里的两个现有示例 确定您特定 LNA 的必要步骤。
添加新设备
登录您的 Helium 控制台，然后转到 Devices 部分并点击 Add device 按钮。
填写必填字段，如设备名称、LoRaWAN 凭证等。
然后点击 Save Device 按钮。
创建解码器函数
下一步是设置将原始字节解码为人类可读形式的函数。
转到左侧面板的 Function 选项卡。然后点击 Add New Function 按钮并为其命名：
复制以下代码然后保存更改。

检查数据
当设备尝试连接到网络时，呼吸灯会闪烁。如果设备成功加入网络，呼吸灯会快速闪烁，并发出轻快的旋律。
然后您可以在 Helium 控制台上查看数据。
注意事项
note
对于在 EU868/RU864 区域运行的用户：
不建议将上传间隔设置为少于 4 分钟。
如果您设置的上传间隔少于 4 分钟，您可能会注意到设备上行链路与当前时间之间的时间戳不对齐。
原理如下：
鉴于 EU868 中 1% 占空比 的限制，设备必须耐心等待大约 4 分钟才能进行每次上行链路传输。此外，Helium 网络仅在累积了 20 个连续的上行链路数据包（ADR 位设置为 1）后才启动数据速率和功率校正。
因此，如果您设置的上传间隔少于 4 分钟，实时数据将暂时存储在 RAM 中，并保持到 Helium 网络触发数据速率和功率校正后再上传。
ChirpStack LNS
对于新用户，要从 Helium 网络上的设备接收数据，必须将其与 LNS（LoraWAN 网络服务器）关联，通常使用公共 LNS 之一，其中许多使用 ChirpStack，但也可以将自己的 LNS 连接到 Helium。
对于熟悉一般流程的用户，简化步骤如下：
- 使用适当的区域和编解码器创建设备配置文件（见下面的源码）
- 使用
devEUI、appKey和包含 AppEUI 的app_eui变量创建设备，这三个值都来自SenseCraft应用
添加设备配置文件
第一步是将 T1000 跟踪器的设备配置文件添加到您的 ChirpStack LNS。 这告诉 LNS 如何解码从 T1000 接收的数据包以及许多其他设置。
在 ChirpStack 仪表板中选择 Device Profiles 并点击 Add device profile。
在常规选项卡中，输入您可以识别的设备配置文件名称并选择适当的区域参数。
LoRaWAN MAC 版本：1.0.4
也可以设置预期的上行链路间隔，它主要控制 LNS 用户界面何时显示设备为活动状态与非活动状态。它对通过 LNS 传递数据包没有影响。
在编解码器选项卡中选择 JavaScript functions 并输入编解码器：
tip
添加应用程序和您的设备
下一步是创建应用程序并向其添加实际设备。
转到 Applications 部分并添加新的应用程序。
然后将设备添加到应用程序并输入之前在 SenseCraft 应用中捕获的 devEUI。
在变量选项卡中添加名为 app_eui 的变量，其值为 SenseCraft 应用中的 AppEUI：
点击提交将显示一个页面，要求输入 AppKey，同样是之前使用 SenseCraft 应用捕获的：
查看设备连接
在 LoRaWAN frames 选项卡中，您将看到一个加载器，然后数据包会在接收/发送时显示出来。
按下 T1000 跟踪器的按钮使其进行测量并发送 join request 连接到 LNS。
发生这种情况后，您应该看到类似这样的内容：
一旦执行了加入过程，T1000 就会发送数据。LNS 会回传一些关于网络频率等的信息，但随后应该只有包含数据的上行链路。
