How this entity was disambiguated

This entity first appeared as the object of triple T8610722 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Bluetooth L2CAP
Context triple: [HSP, requires, Bluetooth L2CAP]

A. BLE
BLE is the abbreviation for the German Federal Agency for Agriculture and Food, a government authority responsible for implementing agricultural, food, and rural development policies.
B. Bluetooth
Bluetooth is a short-range wireless communication technology standard used to connect and exchange data between devices such as phones, computers, headphones, and peripherals.
C. Bluetooth SIG
Bluetooth SIG is the industry consortium that oversees the development, standardization, and licensing of Bluetooth wireless technology.
D. Bluetooth A2DP
Bluetooth A2DP is a wireless audio streaming profile that enables high-quality stereo sound transmission over Bluetooth connections from a source device to headphones, speakers, or other audio receivers.
E. SCTP
SCTP (Stream Control Transmission Protocol) is a transport-layer network protocol designed to provide reliable, message-oriented communication with features like multi-streaming and multi-homing, often used for signaling and real-time data transmission.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
