+// stm32wlx_server.ino
+// -*- mode: C++ -*-
+// Example sketch showing how to create a simple messageing server
+// with the RH_SX126X class. RH_SX126X class does not provide for addressing or
+// reliability, so you should only use on its own RH_SX126X if you do not need the higher
+// level messaging abilities.
+// It is designed to work with the other example stm32wlx_client or rf95_client
+// (dont forget to make sure the madulation schemes and frequencies are the same).
+//
+// 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)
+//
+// Program with eg ST-LINK V2 (a red USB dongle). See the instructions in RH_STM32WLx.h
+
+#include <RH_STM32WLx.h>
+
+// Single instance of the driver. The defaults will work for Seed WiO-E5 mini board, and other boards 
+// equipped with Seeed LoRa-E5 modules, such as NUCLEO_WL55JC1
+RH_STM32WLx driver;

+  // You can change the frequency:
+  //driver.setFrequency(868.0);
+
+  // You can change the modulation parameters with eg
+  //driver.setModemConfig(RH_SX126x::LoRa_Bw125Cr45Sf2048);
+  
+  // You can change the power level in dBm (-9 to +22 on the Wio-E5 mini)
+  // Default is 13dBm
+  //driver.setTxPower(0);
