Abstract
A method enables digital, serial communication over an interface between an electronic device (,) and a battery (,) attached thereto. The digital, serial communication comprises transmission of bytes (,) consisting of a number of bits. The method comprises the steps of transmitting a byte from a first one of said electronic device and said battery, receiving said byte in the other of said electronic device and said battery, and retransmitting said received byte unchanged. Hereby, it is possible to compare the contents of the returned byte with the contents of the byte originally transmitted, and thus ensure that the byte was transmitted correctly. This simple procedure makes other error handling procedures such as parity bits unnecessary.
