U-BLOX NINA B112 FAZENDO ADVERTISING - ESPRUINO (JAVASCRIPT)
O objetivo deste BLOG é demonstrar como é possível utilizar a ESPRUINO (JAVASCRIPT) para programar o módulo U-BLOX NINA B112 e transformá-lo em um dispositivo BLE para "data advertising". Foi utilizado o módulo NINA B112 para o teste.
Advertising allows devices to broadcast information defining their intentions.
O exemplo criado no NINA B112 lê a um SWITCH e detecta SHORT, LONG, SHORT SHORT, SHORT LONG, SHORT LONG SHORT, LONG SHORT LONG.
O exemplo criado no NINA B112 lê a um SWITCH e detecta SHORT, LONG, SHORT SHORT, SHORT LONG, SHORT LONG SHORT, LONG SHORT LONG.
Conforme a sequência, será enviado via advertising os valores 0x80, 0x81, 0x82, 0x83, 0x84 e 0x85.
Também é enviado a tensão da Bateria (VDD) aplicado no NINA B112 e MAC do NINA B112.
Adquirimos então os seguintes componentes
-Botão de RESET;
-Botão de Modo BOOTLOADER (W102);
-Plugável no PROTOBOARD;
-Acesso às várias GPIOS;

Abaixo o roteiro para você seguir:
Espruino é um intérprete de JavaScript para microcontroladores que torna o desenvolvimento de software embarcado rápido e fácil. O intérpretador Espruino é um firmware de código aberto que roda em uma variedade de microcontroladores diferentes.
O Espruino em si não é apenas o firmware ou hardware do interpretador - há também o IDE da Web, ferramentas de linha de comando, documentação, tutoriais e módulos que formam uma solução completa para desenvolvimento de software embarcado..

Grave o código HEX usando o utility J-FLASH LITE ou NRFGO STUDIO no NINA B112 (EVK-NINA-B1)
espruino_2v07.30_nrf52832_mdk.hex
Resete o NINA B112
Instale o ESPRUINO IDE (Native)
Instale o USB DONGLE CSR 4.0 (drivers)
Mas atenção!
Para o Windows 8.1 e posterior
O IDE é capaz de usar os drivers BLE do próprio Windows. A única configuração necessária é que você vá para as configurações de Bluetooth do seu sistema e clique em Conectar (Parear no Windows 10) no seu dispositivo NINA B112. Isso expõe ao sistema e garante que ele apareça no IDE da Web.
Para o Windows anterior ao 8.1
Como as versões do Windows anteriores à 8.1 não suportam Web Bluetooth no sistema operacional, o noble (que o Espruino IDE usa) precisa acessar diretamente o adaptador BLE - portanto, é necessário garantir que o driver WinUSB seja carregado para ele (como oposição a um driver específico do fabricante).
Baixe o Zadig e execute-o - é apenas um executável
Vá para Opções -> Listar todos os dispositivos
Escolha o seu adaptador BLE (o meu é CSR8510 A10)
Certifique-se de que o WinUSB esteja definido como o driver
Agora, quando você executar o IDE da Web nativo e clicar em "conectar" no canto superior esquerdo, deverá ver uma lista de dispositivos BLE conectáveis.
Execute o ESPRUINO IDE (Native)
Faça o SCAN para encontrar o NINA B112
Conecte ao NINA B112

Execução
No Pino GPIO 2 do módulo foi colocado um SWITCH, o qual aterrará o pino quando pressionado.
Ao pressionar o SWITCH, é monitorado se é SHORT, LONG, SHORT SHORT, SHORT LONG, SHORT LONG SHORT, LONG SHORT LONG
Conforme a sequência, será enviado via advertising os valores 0x80, 0x81, 0x82, 0x83, 0x84 e 0x85.
Ao executar o programa no NINA B112, execute um o APP com BLE SCAN
Para executar depois do BOOT
reset();save();
