Communication methods in a bicycle electronic system

A bicycle-implemented communication method, applied in a bicycle electronic system comprising a plurality of electronic components, each electronic component of the bicycle electronic system having zero or more pieces of information attributable thereto and candidate to communication within the bicycle electronic system, each of said attributable pieces of information comprising an identifier which is unique in the bicycle electronic system, the bicycle-implemented transmission method comprising:

• forming, by a first electronic component of the bicycle electronic system, a payload comprising an attributable piece of information and an identifier of an instruction executable by an addressee electronic component,
• setting, by the first electronic component, a value of a characteristic of a Bluetooth Low Energy (BLE) service of a Generic Attribute Profile (GATT) server of a BLE network architecture to said payload, wherein the payload is formatted according to an application-level protocol defined above the GATT layer and independent of GATT attribute semantics;
• transmitting, by the first electronic component, the characteristic to a receiver electronic component to which the addressee electronic component is directly or indirectly connected,
• interpreting, by the receiver electronic component, the instruction identifier and/or the unique identifier of the attributable piece of information contained in the payload independently of the GATT characteristic type;
• and
• forwarding, by the receiver electronic component, the payload to the addressee electronic component or to a different component to which the addressee component is directly or indirectly connected, based on the instruction and/or the identifier of the attributable piece of information, thereby routing the payload across at least one electronic component of the bicycle electronic system beyond a single BLE client-server relationship.
