    Hi Joey,

    The following is my feedback:

     SDA and SCL data lines need 10k pull up resistors. Please make sure to add them if it isn't there already.

    Does this mean that there were spikes in the data line? Please clarify. Adding pull up resistors on the SDA and SCL may help with this.

    Best,
