Hi, i started creating LoRa devices using arduino nano and sx1278 modules and GitHub - sandeepmistry/arduino-LoRa: An Arduino library for sending and receiving data using LoRa radios. .
I realized there are serious problems when i use a separated 3.3v voltage regulator.
Everything works perfect while i use the 3.3v output from arduino (ch340 output)
But problems come when i use an ams1117 3.3v regulator instead, stops receiving at the moment i transmit.
Any idea how to solve this?
