ESP32 LoRa TTNv3

ESP32-LORA-TTNV3

這個示例平台項目每分鐘都會每分鐘發送“ Hello Lora fcnt = nnn'通過Lorawan到Thethingsnetwork。這是TTNV3的測試代碼

初始化構建環境

./INITIALIZE_BUILD_ENVIRONMENT.sh將配置config到private目錄。

在./private/AppConfig.h中進行所有私人設置

LMIC項目設置

在

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

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

Docker

如果您沒有或想安裝平台環境，但是您可以運行Docker引擎。進入docker -Directory

1. ./build.sh-基於ubuntu 20.04構建platformio-esp32 docker圖像
2. ./run_platformio.sh- runns platformio兩次
3. 查找固件.pio/build/heltec_wifi_lora_32/firmware.bin
4. 通過esptool上傳固件

TTNV3有效載荷格式

在TTNv3目錄中查找JavaScript有效載荷格式。
