So I tried loading the example code at this link:
https://docs.arduino.cc/tutorials/nano-33-ble-sense/ble-device-to-device/#testing-the-code
Its meant to connect the Nano 33 BLE to the Nano 33 BLE Sense and using two Nano 33 BLEs not one being a Sense. I believe the connection process should still work and there will be errors because there is a sensor on the Sense board that the Nano 33 BLE doesnt have.
I tried the code exactly as it is provided in the link and I cant get them to connect and I have tried removing anything to do with the sensor that I don't have and they still don't connect.
I also tried using nrfConect and I don't see the peripheral.
