COMPILANDO JAVASCRIPT ESPRUINO PARA U-BLOX NINA B302 NO WSL
(UBUNTU NO WINDOWS)
O objetivo deste BLOG é demonstrar como é possível interpretar programas codificados em JAVASCRIPT (ESPRUINO) no módulo U-BLOX NINA B302 (BREAKOUT).
Ênfase na compilação no WSL2
Adquirimos então os seguintes componentes
-Botão de RESET;
-Botão de Modo BOOTLOADER (W102/106);
-Acesso às várias GPIOS.

Espruino é um intérpretador 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.

O que é WSL2
O Windows Subsystem for Linux (WSL) 2 permite você executar qualquer binário compilado para Linux diretamente no Windows. Eles traz melhorias significativas se comparado ao WSL como uma melhor performance de leitura e escrita em disco e acompanha até um kernel Linux!
Compilando
Uma vez instalado o WSL2 no WINDOWS, abra o PROMPT do UBUNTU e execute
ubuntu@ubuntu:~$ mkdir javascript
ubuntu@ubuntu:~$ cd javascript/
ubuntu@ubuntu:~/javascript$ git clone https://github.com/espruino/Espruino.git

Resete o U-BLOX NINA B302
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 U-BLOX NINA B302. 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 U-BLOX NINA B302
Conecte ao U-BLOX NINA B302
Transfira o SCRIPT JAVASCRIPT abaixo
//variavel on com valor inicial ON
var on = false;
//cria função que é chamada a cada 100ms
setInterval(function() {

//escreve no D13
D13.write(on); //GPIO 1
}, 100);
P0.13 = D13 = IO1 (JAVASCRIPT)
O LED mudará de estado a cada 100ms
