runtime error index out of range

[jzarca01]

hi there,

every time I try to run the program, it immediately crashes with this error

decode-vanmoof-blt-packages \
    -encryptionKey "5825xxxxxxxxxxxxx" \
    -bikeId "ax:xx:xx:xx:xx" \
    -file "bt_snoop.log" <-- exported from PacketLogger as btsnoop
panic: runtime error: index out of range [1] with length 1

goroutine 1 [running]:

main.main()
