If you are unable to create a characteristic object for yourīluetooth Low Energy device on Windows 10, try pairing your device on Windows before using ble to connect to it in MATLAB. To fix this, disconnect and then reconnect your On Windows, if a peripheral device has already been paired but the firmware thatĭefines characteristics and descriptors is changed, ble might fail toĬonnect the device to your computer. If you are trying to create a newīle object for the same device, specify the new UUID instead of the However, the name remains the same in theīlelist output. If your peripheral device powers off or disconnects, the UUID might change when it
If your device transmitsĪdvertisement data less often than once every three seconds, MATLAB might not capture it. The default timeout value is three seconds. For example,īlelist("Timeout",20) searches for nearby peripheral devicesįor 20 seconds. This increases the amount of time MATLAB scans for nearby devices. Try a larger value for the Timeout parameter inīlelist. If your device is already connected in anotherĪpplication or in MATLAB, it might not appear in the output. The output from blelist shows you only nearby devices that areĬurrently advertising data. Bring your peripheral device within range of your computer.ĭisconnect your peripheral device from any other devices or applications first.
