 Changelog
 --------
+- 2019-10-09:    
+  - Tested LoRaWan with a single channel LoRaWan gateway.    
+  - Added support for single channel gateways    
+  - Added support for Insight SIP ISP4520 SoC (nRf52832 + SX1261/2 in one package)    
 - 2019-08-01: Added Espressif ESP8266 support
 - 2019-07-31: Added LoRaWan support (only partly tested)
 - 2019-07-28: Restructure of folders, added nRF52832 support

 Features
 --------
   - Support SX1261, SX1262 and SX1268 chips    
-  - Support of LoRa protocol and FSK protocol (theoretically, I did not test FSK at all)    
+  - Support of LoRa protocol and FSK protocol (theoretical, I did not test FSK at all)    
   - Flexible setup for different modules (antenna control, TXCO control)    
-  - Support LoRaWan node class A, B and C (theoretically, I have no LoRaWan gateway to test it at all)    
+  - Support LoRaWan node class A, B and C tested with single channel LoRaWan gateway

 sentence=Arduino library to use Semtech SX126x LoRa chips and modules to communicate
 paragraph=This library is for LoRa communication with Semtech SX126x chips. It is based on Semtech`s SX126x libraries and adapted to the Arduino framework for ESP32, ESP8266 and Nordic nRF52832. It will not work with other uC`s like AVR.
