Hello, I use your library on arduino uno to make communication between 2 loras e22 900, and work fine. When i try on WEMOS D! esp8266 based it cant communicate, on serial monitor appears all the heads and shows on last line No response from device. I’m using the example code from librarie to get configuration. I’ve tried all pins, changing e testing wires but it doesnt work.
Hi Maykusel,
normally It’s a power supply problem, otherwise, try to reduce the pull-up resistor.

Yeah, I’ve noticed that about power suply, using only usb serial on pc it provide in digital pins 2.8v, then i use an external source. But nothing, i’ll try change the pull up resistors thank you
Renzo, Update,
I pick up an arduino uno, and i test my lora e22, w/ other code, using EBYTE.h a simple code, sending a struct from one devide from another, and works. In next test, i use LoRa_E22.h lib, example code get configuration, and stills saying to check connections. Other test was to use LoRa_E32.h lib and i got data size not matches. Thinking that the wiring is the same in all of this cases…
Hi Mayksuel,
the only thing you can put wrong It’s if you do a wrong configure of M0 and M1.
Bye Renzo
