The specification of the raw data format is incomplete. It explains how the raw packet is structured, with all bytes after byte 9 being the “Advertising Data” - but it does not break down the advertising data. Where, for example, is the MAJOR and MINOR stored? (note: I can find documentation for the JSON format used with MQTT, but not for the RAW format used in HTTP Client mode).
Please check the link for advertising data
