MÓDULOS E KITS LoRa/LoRaWAN, LoRa MESH - PRIMEIROS PASSOS: LSM110A - CONEXÃO LoRaWAN - SDK STM32

Objetivo

Este documento é um guia básico (resumo) sobre instalação do STM32CubeIDE para a módulo LoRa/SigFox LSM110A LoRa/Sigfox da Seongji então gerar o APP EndNode, bem como os primeiros acessos à rede LoRaWAN e envio de pacotes. Também é mostrado como configurar para trabalhar em uma faixa de frequências e região.

Baseado no Software do oficial da STM, modificado para rodar no LSM110A, também faz a conexão com o servidor CHIRPSTACK ao pressionar o botão e permanece enviando a temperatura para o servidor a cada 30 segundos.

Há também funções de SLEEP , WAKE UP, BAIXO CONSUMO.

Utiliza uma STATE MACHINE.

Colaboração de um cliente SmartCore

STM32CubeWL-smartcore.7z

PS: tive que criar a pasta

C:/STM32Cube/Repository/STM32Cube_FW_WL_V1.3.0/Drivers/STM32WLxx_HAL_Driver/Src/stm32wlxx_hal_i2c.c \
C:/STM32Cube/Repository/STM32Cube_FW_WL_V1.3.0/Drivers/STM32WLxx_HAL_Driver/Src/stm32wlxx_hal_i2c_ex.c \

e copiar os drivers do SDK STM32 para lá.

PS: drivers podem ser copiados daqui

C:\STM32CubeWL-smartcore\Drivers\STM32WLxx_HAL_Driver

e comentar linhas do main.c

//#include "declareFunctions.h"

O projeto é

LSM110A Starter KIT

Módulo

O LSM110A é um módulo de última geração que integra o STMicroelectronics STM32WL.

Baixando o SDK

STMicroelectronics/STM32CubeWL: STM32Cube MCU Full FW Package for the STM32WL series - (HAL + LL Drivers, CMSIS Core, CMSIS Device, MW libraries plus a set of Projects running on boards provided by ST (Nucleo boards) (github.com)

PS: no caso, baixe o ZIP acima, STM32CubeWL-smartcore .7z

No caso, foi realizado via Prompt de Comando, com o GIT já instalado no Windows, mas você pode baixar em ZIP do repositório e descompactar.

C:\>git clone https://github.com/STMicroelectronics/STM32CubeWL.git

PS: no caso, baixe o ZIP acima, STM32CubeWL-smartcore .7z

Compilação do Firmware

Para gerar o firmware para o LSM1x0A, será necessário que você instale o STM32CubeIDE em sua máquina.

Compilando

Este aplicativo conectará o LSM110A com CHIRSTACK e enviará dados após a conexão com um gateway LoRaWAN®.

Passo 1. Visite o repositório STMicroelectronics/STM32CubeWL: STM32Cube MCU Full FW Package for the STM32WL series - (HAL + LL Drivers, CMSIS Core, CMSIS Device, MW libraries plus a set of Projects running on boards provided by ST (Nucleo boards) (github.com) e baixe como um arquivo ZIP

PS: no caso, baixe o ZIP acima, STM32CubeWL-smartcore .7z

pir

Etapa 2. Extraia o arquivo ZIP e navegue até C:\STM32CubeWL\Projects\NUCLEO-WL55JC\Applications\LoRaWAN\LoRaWAN_End_Node\STM32CubeIDE
Etapa 3. Clique duas vezes no arquivo .project

Etapa 4. Clique com o botão direito do mouse no projeto e clique em Properties

pir

Etapa 5. Navegue até C/C++ Build > Settings > MCU Post build outputs, marque Convert to Intel Hex (-O ihex) e clique em Apply and Close

pir

Etapa 6. Clique em Build 'Debug' e ele deve compilar sem erros

construir

pir

Etapa 7. A região LoRaWAN® padrão é EU868, você pode modificá-la, definindo a definição de macro ACTIVE_REGIONemLoRaWAN/App/lora_app.h

 // LoRaWAN/App/lora_app.h
/* LoraWAN application configuration (Mw is configured by lorawan_conf.h) */
/* Available: LORAMAC_REGION_AS923, LORAMAC_REGION_AU915, LORAMAC_REGION_EU868, LORAMAC_REGION_KR920, LORAMAC_REGION_IN865, LORAMAC_REGION_US915, LORAMAC_REGION_RU864 */
#define ACTIVE_REGION LORAMAC_REGION_AU915 //<=====================
//lorawan_conf.h#define LORAMAC_SPECIFICATION_VERSION                   0x01000300 //<=====1.0.3
#define REGION_AU915

pir

Passo 8. Após as modificações acima, rebuild o exemplo e programe para o seu LSM110A. Abra STM32CubeProgrammer, conecte o ST-LINK ao seu PC, segure RESET Buttonseu dispositivo, clique Connecte solte RESET Button:

Conectando S-TLINK V2 no LSM110A Starter KIT, via SWD, Reset antes de gravar

pir

Etapa 9. Certifique-se de que a proteção de leitura esteja AA, se for exibida como BB, selecione AAe clique em Apply:

pir

Etapa 10. Agora, vá para a Erasing & Programmingpágina, selecione o caminho do arquivo hexadecimal (por exemplo: C:\STM32CubeWL-smartcore\Projects\NUCLEO-WL55JC\Applications\LoRaWAN\LoRaWAN_End_Node\STM32CubeIDE\Debug\LoRaWAN_End_Node.hex), selecione as opções de programação conforme a imagem a seguir e clique em Start Programming!

pir

Você verá a mensagem Download verificado com sucesso , assim que a programação terminar.

Etapa 11. Se o seu LoRaWAN® Gateway e CHIRPSTACK estiverem configurados, o LSM110A será conectado com sucesso após a reinicialização!

Alterando BAND MASK

Em RegionAU915.c, a máscara utilizada para compatibilizar com configuração utilizada no Gateway LoRaWAN

// Initialize channels default mask
            /* ST_WORKAROUND_BEGIN: Hybrid mode */
.

.
.
#else
            RegionNvmGroup2->ChannelsDefaultMask[0] = 0xFF00;
            RegionNvmGroup2->ChannelsDefaultMask[1] = 0x0000;
            RegionNvmGroup2->ChannelsDefaultMask[2] = 0x0000;
            RegionNvmGroup2->ChannelsDefaultMask[3] = 0x0000;
