+  RadioLib LR11x0 Transmit with Interrupts Example
+
+  This example transmits LoRa packets with one second delays
+  between them. Each packet contains up to 256 bytes
+  of data, in the form of:
+  - Arduino String
+  - null-terminated char array (C-string)
+  - arbitrary binary data (byte array)
+
+  Other modules from LR11x0 family can also be used.
+  
+  This example assumes Seeed Studio Wio WM1110 is used.
+  For other LR11x0 modules, some configuration such as
+  RF switch control may have to be adjusted.
+
+  For default module settings, see the wiki page
+  https://github.com/jgromes/RadioLib/wiki/Default-configuration#lr11x0---lora-modem
+
+  For full API reference, see the GitHub Pages
+  https://jgromes.github.io/RadioLib/
