Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a walkie-talkie, an LCD screen walkie-talkie with bluetooth. Background technique [0002] At present, there is an urgent need for long-distance and fast communication equipment in the community, construction and groups. The common walkie-talkies on the market are all developed and short-distance. Many walkie-talkies can receive them, and information cannot be kept confidential. [0003] At the same time, it is very inconvenient for one person to carry two communication devices, a walkie-talkie and a mobile phone. At present, there is no one on the market that can have both of the above two devices at the same time. Therefore, it is urgently needed to develop a walkie-talkie that can have both requirements. Contents of the invention [0004] Therefore, in view of the above-mentioned problems, the object of the present invention is to provide a LCD screen interco...
