Olá Pessoal, estou trabalhando em um projeto pessoal e nele estou usando a lib
PN5180-Library, para leitura do sensor FreeStyle Libre. O código funcionava sem esse erro há uns 2 meses atrás, voltei a trabalhar nele e agora esta dando o seguinte erro.
O que estou usando: ESP32, PN5180 com a lib mencionada a cima.
