In this project, we implement a BLE data collector/hub which plays as central(client) role and collects data from multiple peripheral(server) devices. Data is transmitted between BLE Producer and BLE Collector through customized BLE service data_transfer_service, besides, between BLE Collector and Host through USB.
The overall protocol for data transmission from BLE Producer(UWB Anchors) through BLE Collecotr(NRF52840 Dongle) to Host(PC) is shown as follows:
This project mainly deals with module BLE Collector, moreover, its data flow for Data/CMD/LOG channels is specified below:
