...by a Arduino Uno with a GSM board on top. The GSM board should always wait for an incoming call. If there is a call, the GSM modul should take the call and forward the Audio signal to it´s Audio output. This output signal is then been taken to our amplifier and forwarded to an outdoor speaker. If the call is finished, the GSM board should hang up and wait for the next call. Actually the amplifier is always in stand by and an incoming audio signal ( from the GSM Modul ) will switch it to active. This should be changed later on, so that an output Pin of the Arduino will switch the amplifier to active. Another option would be to show the signal strength ( by an LED or similar ). That has to be defined later on. The boards are: Processor Board: ...

Hallo, wir arbeiten derzeit an einer mobilen Sensorbox, deren Messdaten über GPRS an einen Webserver geschickt werden. Die Box nutzt einen Arduino MKR GSM 1400 (SAMD Prozessor). Unser Problem ist die SSL Verschlüsselung, insbesondere von Arduino-Seite (eine unverschlüsselte Lösung haben wir bereits). Explizit geht es darum, einen Datenstring SSL-verschlüsselt an einen (Socket-)Webserver zu schicken. Das Projekt müsste in Zusammenarbeit mit unseren Adminis laufen (bzw. zumindest abgesprochen werden), da diese von der Serverseite aus alles absegnen müssen.
