AWS S3 OTA Update HTTPS para Arduino com ESP32

Inspirado em: AWS_S3_OTA_Update e em httpUpdateSecure

Propósito

Executar uma atualização OTA no ESP32 de um arquivo localizado no Amazon S3 usando HTTPS com framework arduino-esp32

Preparando o arquivo na Amazon S3

1. Faça o upload do arquivo binário para sua conta do Amazon S3, em um bucket de sua escolha
2. Uma vez carregado, dentro do S3, selecione o arquivo bin >> Mais (botão no topo da lista de arquivos) >> Tornar público
3. Sua URI do S3 deve ser algo assim: https://bucket-name.s3.ap-south-1.amazonaws.com/sketch-name.ino.bin
4. Copie a URI dispare-a no seu navegador ou faça o curl curl -I -v https://bucket-name.ap-south-1.amazonaws.com/sketch-name.ino.bin para validar o mesmo

Build e Upload

1. Carrege o arquivo para seu sketch do arduino
2. Configure com seu WIFI_SSID, WIFI_PASSWORD e a URI do arquivo .ino localizado na Amazon S3
3. Compile(build)
4. Carrege(upload) o sketch para o módulo
5. Use o monitor serial para ver a saída

Saída esperada
