U-BLOX NINA B302 e WIFI - ARDUINO - AT COMMANDS
O objetivo deste BLOG é mostrar um exemplo em ARDUINO que permite o NINA B302 se transformar num webserver WIFI, utilizando o W102 (COMANDOS AT) COMO COPROCESSOR WIFI 802.11.
Utilize a programação clássica com Sockets do Arduino! Compilei a última versão dos comandos AT disponível. Alguns pequenos bugs revolvidos!

COPROCESSOR PARA O NINA B302
MONTAGEM
Adquirimos então os seguintes componentes
-Botão de RESET;
-Botão de Modo BOOTLOADER (W102);
-Plugável no PROTOBOARD;
-Acesso às várias GPIOS;
Pequena
Abaixo o roteiro para você seguir:
Baixe e instale o Arduino IDE
Inicie o Arduino IDE, vá em Preferências e adicione
https://www.adafruit.com/package_adafruit_index.json
Abra o Boards Manager no menu Tools -> Board e instale o "Adafruit nRF52 by Adafruit"
Selecione sua placa nRF5 no menu Ferramentas -> Placa
Adafruit Bluefruit nRF52 Feather
OBSERVAÇÃO: Durante a instalação, o Arduino IDE leva alguns minutos para extrair as ferramentas após o download, por favor, seja paciente.
Use o gravador SEGGER JLINK para gravar o BREAKOUT com módulo NINA B302, conecte nos pinos do SWCLK (pino 7) e SWDIO (pino 9) do SEGGER JLINK nos pinos SWDCLK e SWDIO do BREAKOUT (pinos nas laterais, próximo à antena). Não esquecer de ligar os GND do BREAKOUT no GND do SEGGER JTAG, bem como alimentar o BREAKOUT com 3.3V.
Ligue os pinos SWD DIO e CLK ...
...nestes pinos da placa BREAKOUT
Você pode também usar o ST-LINK V2
Abra J-FLASH lite e grave o bootloader da Adafruit
O mesmo se encontra em
....\packages\adafruit\hardware\nrf52\0.19.0\bootloader\feather_nrf52840_express
Compile depois para o NINA B302
https://github.com/adafruit/Adafruit_nRF52_Bootloader
Com ele, você poderá transferir programas via DFU USB. Maiores detalhes sobre este bootloader
https://learn.adafruit.com/introducing-the-adafruit-nrf52840-feather/update-bootloader
Segundo a documentação, se você pressionar o reset, o módulo aguardará por um certo tempo se há algo sendo enviado pelo Arduino, ou seja, o programa a ser gravado via DFU.
ATENÇÃO, o bootloader usa USB para gravação do NINA 302, OU SEJA, CRIA UMA COMM VIRTUAL, TAMBÉM PARA SER A SERIAL PADRÃO DO ARDUINO
INSTALE OS DRIVERS
https://github.com/adafruit/Adafruit_Windows_Drivers
Conecte na USB + e USB - um cabo USB, AGUARDE INSTALAR OS DRIVERS
Aqui você encontra variant.cpp e variant.h e boards.txt
https://ricardoadulis.sharepoint.com/:f:/r/sites/smartcore/Shared%20Documents/---%20SmartCore%20-%20tecnico%20publico/NINA%20B302/Arduino_variant?csf=1&web=1&e=7URfTD
Ao copiá-los e executar o ARDUINO teremos o NINA B302 na lista.
ÓTIMA REFERENCIA PARA PINOS DO ARDUINO E PINOS (GPIOS) DO NINA B302
https://www.u-blox.com/sites/default/files/NINA-B3_DataSheet_%28UBX-17052099%29.pdf
Ligue os pino do NINA B302 no NINA W102
INSTALE LIB AT WEBSERVER - EXEMPLOS QUE USAM AT COMMANDS (ESPRESSIF)
BREAKOUT B3 | BREAKOUT W102 | ||
TXD | IO23 | TXD | IO22 |
| RXD | IO22 | RXD | IO23 |
| GND | GND |
INSTALE LIB AT WEBSERVER - EXEMPLOS QUE USAM AT COMMANDS (ESPRESSIF)
Thanks to Khoi Hoang to help to port AT to NINA B302
Compile o programo AdvancedWebServer e pressione o botão para gravar.
Ao aparecer a mensagem "Upgrading target on COM...", pressione imediatamente o botão de reset do módulo NINA B302
Como podem observar, o programa será transferido!
