  • Yes, I am using Serial1.

    I2C1.setup({scl: B6, sda: B7}); // NFC module
    Serial1.setup(9600, { rx: A3, tx : A2 }); // BLE module
    

    e; will try both when i get back home;
    e2; while thinking about it a bit closer, the error might have came up when i tried Serial2, because Serial1 wasn't giving me any response.
