Communication method and apparatus for hydrogen fueling based on interoperability

A communication apparatus for hydrogen fueling deployed in a hydrogen fueled mobility, comprising:

• a memory storing at least one instruction;
• and
• a processor executing the at least one instruction,
• wherein the processor, is configured to:
• discover a dispenser that supplies hydrogen to the mobility, and performing at least a part of a paring process by exchanging at least one message with the dispenser, based on a first communication protocol common between the dispenser and the mobility;
• and
• perform, one or more of a first process sequential to the at least the part of the pairing process or a subsequent process to the first process, using a second communication protocol determined to replace the first communication protocol in the first process,
• wherein the second communication protocol is a fallback protocol of the first communication protocol, and is supported commonly by the mobility and the dispenser.
