@Lazar-Demin Great to see it working. If you need a gateway you can also use a ESP8266 NodeMCU board with another RFM95 module and configure and flash the https://github.com/things4u/ESP-1ch-Gateway-v5.0 firwmare on it, also see http://things4u.github.io/. Needs a little bit of fiddling around with the configuration and pinout; Also be aware that the EUI of the TTN gateway must be the one that the firmware spits out on startup (it's made up of the ESP8266's MAC address and two 0xff in the middle).
