 What can be seen is that after sending the "join" message, the LMIC stack waits
 5 seconds for the receive window and receives the acknowledgement from the LoRa gateway.
 
+## Example "periodic"
+Directory: /examples/periodic
+
+Modifications necessary: 
+
+File /examples/periodic/main.c:
+
+* Adapt "application router ID (LSBF)" like already described under examples/join.
+* Adapt "unique device ID (LSBF)" like already described under examples/join.
+* Adapt "device-specific AES key " like already described under examples/join.

+
+Added code that reads the CPU temperature of the RPi and returns it as a 2 byte integer
+value.
+
+This examples does a "joins" the network and then sends a sensor value (the CPU temperature)
+every 60 seconds as an unconfirmed message with a payload of 2 bytes.
