Abstract

The invention discloses a projection interaction system. The interaction process of the projection interaction system comprises the steps that: a remote controller sends a Bluetooth pairing request to a projector, and a Bluetooth module of the projector completes the Bluetooth pairing connection with the remote controller based on the Bluetooth pairing request; the Bluetooth module of the projector transmits a pre-stored custom attribute to the remote controller in Bluetooth pairing connection through a GATT protocol; the remote controller receives the custom attribute and stores a chip manufacturer identifier in the custom attribute in a GATT transaction of the remote controller; the remote controller extracts the chip manufacturer identifier in the GATT transaction, synthesizes a power-on broadcast according to the chip manufacturer identifier, and broadcasts the power-on broadcast outwards as broadcast information; and when the Bluetooth module of the projector receives broadcast information and a main control chip successfully analyzes the broadcast information, a power button in the key board is triggered. The interactive compatibility of the remote controller relative to various projectors is improved.

Description

technical field [0001] The present application relates to the technical field of projector intelligent control, in particular to a projection interaction system. Background technique [0002] The bluetooth interaction between conventional projector and remote control, different bluetooth module chip manufacturers have different start-up broadcast formats, it is necessary that the bluetooth module of the projector and the bluetooth chip of the remote control are from the same manufacturer, one remote control can only be used For the control of projectors from the same Bluetooth chip manufacturer, the interactive compatibility of the remote control with respect to the projector is poor. Contents of the invention [0003] The main purpose of the embodiments of the present application is to provide a projection interaction system, aiming at solving the technical problem of poor interactive compatibility of the remote control with respect to the projector. [0004] In order to...
