The connection is not always successful at the first attempt, you can try again: close the auscultation window and open a new one by clicking on “New auscultation”, until the Bluetooth icon changes to
garnet. If the connection is successful, you will also see the blue acquisition LED light up.

If you have difficulty connecting via Bluetooth, change the connection mode: connect the device via USB and the connection will be made almost immediately via USB.

Be careful, if you change the connection mode of the device, you must remember to change it in the software configuration: Serial USB or Bluetooth
