The Things Network LoRaWAN Stack V3 学习笔记 2.6 新增一个 CN470 子频段

前言

目前 Stack 在 CN470 采用的是 FSB_11 子频段，手头的网关大多使用 FSB_1，本篇笔记演示如何为 Stack 新增一个子频段。

小能手这段时间在学习 The Things Network LoRaWAN Stack V3，从使用和代码等角度对该 Stack 进行了分析，详细可点此查看。

1 现有的频段处理

TTN 默认是抓取了自己的 github 仓库。

// DefaultFrequencyPlansConfig is the default config to retrieve frequency plans.
var DefaultFrequencyPlansConfig = config.FrequencyPlansConfig{
	URL: "https://raw.githubusercontent.com/TheThingsNetwork/lorawan-frequency-plans/master",
}

2 Fork仓库进行修改

Fork 了 TTN 的仓库来做修改，主要是新增 CN_470_510_FSB_1.yml，并且在 frequency-plans.yml 进行登记。

3 stack 配置环境变量

将频点计划的 URL 改为我的 github 。

export TTN_LW_FREQUENCY_PLANS_URL=https://raw.githubusercontent.com/twowinter/lorawan-frequency-plans/master
