Es gibt für Bluetooth Low Energy kein Standard Profile, welches die Übertragung von Daten wie z.B. mit dem Serial Port Profile beim klassischen Bluetooth unterstützt. Dies ist jetzt mit dem eigens hierfür entwickelten Lintech BLE SPP Profile möglich. Mit dieser App kann man eine serielle Datenverbindung über Bluetooth Low Energy zu Geräten aufbauen, die das LinTech SPP Profile unterstützen: - LinTech Bluetooth Low Energy RS232 Datenadapter - LinTech Bluetooth Low Energy USB Datenadapter - LinTech Bluetooth Low Energy SPP Testboard - LinTech BLE Module mit SPP Profile Die App kann Zeichen im ASCII/HEX Format, Kommandos oder einstellbare Byte-Blöcke zur Gegenstelle senden oder empfangen. Die ausgehenden Daten sind Schwarz, die eingehenden Daten sind in Magenta dargestellt. 1) Starten Sie die App und klicken Sie auf "Scan" um nach Lintech BLE SPP Geräten zu suchen 2) Wählen Sie aus der Liste das Gerät aus mit dem Sie sich verbinden möchten 3) Werden Sie aufgefordert sich mit dem Gerät zu koppeln, geben Sie den geforderten Passkey ein, da sonst keine Kommunikation möglich ist 4) Ist die Verbindung hergestellt, können Sie die Datenkommunikation testen Um die App sinnvoll nutzen zu können, ist es wichtig die Gegenstelle so zu verwenden, dass ankommende Daten auch gesehen werden. Sie können z.B. ein Terminal Programm verwenden, welches auf den Com-Port zugreift, an welchen das BLE SPP Gerät angeschlossen ist und so die Datenkommunikation verfolgen. Die App empfängt und versendet die Daten auch wenn Sie im Hintergrund läuft.
