+// stm32wlx_continuous.ino
+// -*- mode: C++ -*-
+// Example sketch showing how to start a continuous carrier wave transmission
+// for measuring power output. CAUTION: it may be illegal for you to transmit continuously
+// without a dummy load.
+//
+// In order to use the Arduino IDE to program the Wio-E5, you must
+// install the stm32duino package using these instructions:
+//   https://community.st.com/t5/stm32-mcus/stm32-arduino-stm32duino-tutorial/ta-p/49649
+// Tested with Wio-E5 mini. In Arduino, select:
+//   Tools -> Board -> STM32 MCU based boards -> LoRa boards
+//   Tools -> Board part number -> LoRa-E5 mini
+//   Tools -> U(S)ART support -> Enabled (generic Serial)
+// Caution: it is probably possible to damage your chip by setting high power levels
+// without a suitable RF termination.
