+is set up:
+
+```python
+import broadlink
+import base64
+
+devices = broadlink.discover(timeout=5)
+devices[0].auth()
+```
+
+For each code, the procedure is as follows:
+
+```python
+devices[0].find_rf_packet()
+# wait until this returns True
+
+devices[0].check_data()
+# this will return the code
+```
