Indoor　positioning　refers　to　the　location　positioning　in　indoor　environment,　using　various　technologies　such　as　base　station　positioning　and　wireless　communication　to　determine　the　location　of　people　in　indoor　space.　In　this　paper,　we　propose　an　indoor　positioning　solution　using　fingerprint　technology　with　the　help　of　low-power　Bluetooth　technology　platform　to　address　the　shortcomings　of　the　current　fingerprint　positioning　technology,　and　carry　out　error　analysis　and　fingerprint　signal　filtering　in　the　offline　training　phase　and　online　positioning　phase.　The　aim　is　to　contribute　new　ideas　and　methods　to　the　research　in　the　field　of　accurate　positioning.　©　2021　ACM.
