O objetivo deste BLOG é demonstrar como é possível utilizar o RTOS Mynewt para programação do WISOL LOM204. Foi utilizado o Starter Kit LOM204 para o teste. O exemplo permitirá via linha de comandos o acesso à rede LoRaWAN e então será enviado um texto "HELLO" via OTA, AU915, ao servidor LoRaWAN CHIRPSTACK.
BETA - EM TESTES - APENAS PARA PROGRAMADORES COM mynewt RTOS
Baseado no B-L072Z-LRWAN1
Compilado no MYS2 (Linux no Windows)
Módulo
Ênfase na compilação no WSL2 (Ubuntu)
O que é ChirpStack
ChirpStack é um Servidor de Rede LoRaWAN de código aberto que pode ser usado para configurar redes LoRaWAN. O ChirpStack fornece uma interface web para o gerenciamento de gateways, dispositivos e inquilinos, bem como para configurar integrações de dados com os principais provedores de nuvem, bancos de dados e serviços comumente usados para lidar com dados de dispositivos. O ChirpStack fornece uma API baseada em gRPC que pode ser usada para integrar ou estender o ChirpStack.

Fácil de usar
Componha, ajuste e crie sua imagem em horas ou até minutos.
- Inicialização de hardware em arquivo de configuração única para o BSP escolhido
- Inicialização de parâmetros de serviço em um único arquivo de configuração para o módulo escolhido, e. Controlador BLE
- Gerenciamento inteligente de pacotes e construção usando a ferramenta Newt
- Auditorias automáticas de configuração usando o Newt Tool
LOM204A e o Apache Mynewt
Como o módulo LOM204A é baseado no chip STM32L0 (CPU), será possível rodar o Apache Mynewt sem problemas. O usuário deve dar atenção ao mapeamento de GPIOS de acesso ao SX1276 (Semtech LoRa).

Configuração do APP (Credenciais)
Antes de criar o aplicativo e ingressar em uma rede LoRaWAN, você precisa de uma conta em um provedor de back-end LoRaWAN. Em seguida, crie um aplicativo LoRaWAN e registre seu dispositivo. Como este aplicativo foi fortemente testado com o backend fornecido pelo CHIRPSTACK. Assim que seu aplicativo e dispositivo forem criados e registrados, você terá várias informações (fornecidas pelo provedor LoRaWAN).
Assim que seu aplicativo e dispositivo forem criados e registrados, você terá várias informações fornecidas pelo provedor LoRaWAN:- O tipo de procedimento de JOIN: ABP (Ativação por personalização) ou OTAA (Ativação Over The Air)
- O dispositivo EUI: uma matriz de 8 bytes
- A aplicação EUI: uma matriz de 8 bytes
- A chave do aplicativo: uma matriz de 16 bytes
- O endereço do dispositivo: uma matriz de 4 bytes, necessária apenas com o procedimento de junção ABP
- A chave de sessão do aplicativo: uma matriz de 16 bytes, necessária apenas com o procedimento de junção ABP
- A chave de sessão de rede: uma matriz de 16 bytes, necessária apenas com o procedimento de junção ABP
- Depois de obter essas informações, edite o Makefile adequadamente ou use os comandos set/get no shell do aplicativo de teste.
