We're two mobile service researchers in Sweden who would need help with connecting bluetooth hardware. Our use case involves sending small data packets over 100 yards or more, several senders to a common receiver. We'd like some help with connecting two or more Arduino Nano BLE (SENSE) boards to a gateway computer as a receiver, typically with a USB dongle (like the Nordics nRF52840 Dongle).
You'll need two Arduino Nano 33 BLE SENSE, and one dongle + some kind of computer (linux) to act as gateway; such as a Raspberry Pi, Vero (OSMC) or similar.
(1) The sender needs to collect some data, and send it over Bluetooth with long-range settings, .i.e Coded phy. Sending its rssi value and hardware adress would be quite enough.
(2) The receiver listens, and picks messages up, sorted it based on the client ID respectively, and presents it in e.g. on a web page locally .
