 For each discovered device a panel with device information is shown. It contains device name, connectable status, tx power (if available), RSSI value, mac address, advertised services, service data and manufacturer specific data.
 If the UUID of a service or the company ID in the manufacturer data is in the official Bluetooth list of assigned numbers, the official name will be shown.

 Depending on the properties of each characteristic different buttons get added to the text field. Those are Read, WriteCommand, WriteRequest, Notify and Indicate. Data from/to a characteristic gets displayed or entered into a text field, which is either read/write or read only. You can switch the presentation between HEX numbers or ASCII string. When set to ASCII, non-printable characters are displayed as a black square.
