Hello everyone, I am a Computer Science and Engineering student. My graduation project is an emergency communication system with Meshtastic via Arduinos!
I have started modifying the firmware for it and actually reset it. I’m trying to restore the original firmware, but I haven’t been able to do so yet. Currently, I’ve installed Wifi_LoRa_32_FactoryTest_V1.ino, but it’s not the same as the original firmware I had. I need the original one. That’s my first question.
My second question is, I’ve implemented a T9 keyboard on a 4x4 Arduino keypad with a 16x2 LCD screen. What do I need to do to communicate with my second Heltec device (by the way, I’ve reset its firmware too 
)?
Please don’t misunderstand me, I’m not very good with hardware stuff, don’t judge me, I need some help.
Thank you for your answers! Please respond to my questions in order. Have a great day!
