A method enables digital, serial communication over an interface between an electronic device (102) and a battery (103) attached thereto. The digital, serial communication comprises transmission of bytes (300) 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.

L'invention concerne un procédé permettant la communication numérique série par une interface entre un dispositif électronique (102) et une batterie (103) fixée à ce dernier. La communication numérique série consiste en la transmission d'octets (300) constitués d'un certain nombre de bits. Ledit procédé consiste à transmettre un octet du dispositif électronique, à recevoir ledit octet dans ladite batterie, ou à le transmettre de la batterie et à le recevoir dans le dispositif électronique, et à retransmettre ledit octet inchangé. Il est ainsi possible de comparer le contenu de l'octet renvoyé au contenu de l'octet transmis à l'origine, et de vérifier que l'octet a été transmis correctement. Cette procédure simple rend inutiles d'autres procédures de traitement des erreurs, telles que l'utilisation de bits d'imparité.
