Background

When the initial firmware for the LD2450 was released (May '23), the multiplayer mode wasn't fully available, being able to detect more than one person, but in the end keeping the most active target.

Hilink promised to provide this setting, and after a long wait, in mid-October '23, a new firmware and a new APP (HLKRadarTool V1.4.0) finally gave us multiplayer mode. As well as, in true Hilink style, a separate setup feature was turned on for the Bluetooth protocol.

We'll summarize some of the information we know here, along with an explanation from the Hilink developers. Hopefully this will help you understand the feature better.
