2 years ago Kirill, Privyet! Good to hear from my comrades in Russia. I've had the pleasure of visiting Moscow a few times over the years, hopefully I can visit Russia again. Here's a photo of me at the Kremlin back in 2005. Thanks for sending the wiring diagram and I see the issue. the Rx line on the MCU must connect to the Tx line on the EBYTE. This is a strange, but the EBYTE transmitter sends data through the Tx line and the MCU receives through the Rx line. You will need to reverse the connections for your transmitter and reciever. Let's start there and see if that helps. Spi Ceba,
Kris Kasprzak
