FAZENDO PROPAGANDA DE DADOS BLE SEM CONEXÃO COM NINA B112
Numa comunição BLE, normalmente os periféricos fazem propaganda da sua existência, para que a central se conecte e solicite a leitura de dados. As vezes os dados podem ser enviados sem conexão, ou seja, os periféricos ficam mandando continuamente e via (scanner) central, podem obtê-los.
Foi utilizado o EVK-NINA-B1 para testes.
O exemplo abaixo, desenvolvido no SEGGER STUDIO é um exemplo. Foi criada um variável Propaganda que é incrementado todas vez que o dado (Advertising) deve ser atualizado. Propaganda é inserido no campo Manufacturer o qual faz parte do pacote de Advertising.
