I'm using 2 Lora e32 and 2 node MCU v3 to test send data with your example. However my receiver not receive what my transmitter send T.T
this is my transmitter code( I wire the same as in the code):
/*
* LoRa E32-TTL-100
* Send fixed transmission structured message to a specified point.
* https://mischianti.org
*
* E32-TTL-100----- Arduino UNO or esp8266
* M0 ----- 3.3v (To config) GND (To send) 7 (To dinamically manage)
* M1 ----- 3.3v (To config) GND (To send) 6 (To dinamically manage)
* TX ----- PIN 2 (PullUP)
* RX ----- PIN 3 (PullUP & Voltage divider)
* AUX ----- Not connected (5 if you connect)
* VCC ----- 3.3v/5v
* GND ----- GND
*

My receiver receive "Ok" not "Prova" and I'm struggle for days now T.T. I really need help
