ESP32 LoRa TTNv3

ESP32-LORA-TTNV3

这个示例平台项目每分钟都会每分钟发送“ Hello Lora fcnt = nnn'通过Lorawan到Thethingsnetwork。这是TTNV3的测试代码

初始化构建环境

./INITIALIZE_BUILD_ENVIRONMENT.sh将配置config到private目录。

在./private/AppConfig.h中进行所有私人设置

LMIC项目设置

在

.pio/libdeps/<board name>/MCCI LoRaWAN LMIC library/project_config/lmic_project_config.h

例如#define CFG_eu868 1 for Europe 868MHz发件人/接收器

Docker

如果您没有或想安装平台环境，但是您可以运行Docker引擎。进入docker -Directory

1. ./build.sh-基于ubuntu 20.04构建platformio-esp32 docker图像
2. ./run_platformio.sh- runns platformio两次
3. 查找固件.pio/build/heltec_wifi_lora_32/firmware.bin
4. 通过esptool上传固件

TTNV3有效载荷格式

在TTNv3目录中查找JavaScript有效载荷格式。
