    Hi user4206464,

    The schematic looks good to me. 

    Sifos hasn't released the BT test suite with passing and failing report. Are you using Sifos AT test suite? 

    If that's the case, you are expected to see some failures as the IEEE802.3bt standard has different spec for detection classification time. 

    Regarding your specific issue, what configuration of TPS23881 is set? Can you send me your command to configure PSE registers? 0x12, 0x29 especially. Thanks.

    Best regards,

    Penny
