One bug was fixed in HDLC_ICEC_LIB_CK.py:

def bit_destuffing(IN):
    OUT=np.arange(256)
    k=0
    num=0
    for i in range(256-8):
        if IN[i+8]==0:
            # if num == 5:
            if (num==5 and list(IN[i+8:i+8+8]) != [0,1,1,1,1,1,1,0]):
                # print("bit de-stuffing")
                num=0
            else:
                num=0
                OUT[k]=0
                k=k+1
        elif num==6:
            #print("done")
            break;
        else:
            num=num+1
            OUT[k]=1
            k=k+1
    return OUT[0:k-6]
