RE: Bluetooth connection between Arduino NANO 33 BLE Sense and NRF52840 DK

[quote userid="98449" url="~/f/nordic-q-a/71761/bluetooth-connection-between-arduino-nano-33-ble-sense-and-nrf52840-dk"]I'd like to deliver the Arduino's sensor data to DK board via Bluetooth[/quote]

The whole point about Standards like BLE is that it is entirely independent of what hardware is used.

The communication is entirely defined by the GATT Characteristics and Services.

[quote userid="98449" url="~/f/nordic-q-a/71761/bluetooth-connection-between-arduino-nano-33-ble-sense-and-nrf52840-dk"]Is it possible to connect with the arduino BLE using the example ble_app_uart_c on the DK board?

You need to find out the GATT Characteristics and Services used by the Arduino - and use that.

If that happens to be the proprietary Nordic UART Service (NUS) then, of course, the NUS Central will work - and, if it's not, then it won't!

If NUS is used, it is just a "stream" of arbitrary data - so you will still need to consult the Arduino documentation to see how they've formatted/structured the sensor data over the NUS link.

For Arduino support, you will need to go to the Arduino forums, and/or the board manufacturer.
