Hi, I am having a problem in communicating between 3 nodes and 1 gateway. I place a gateway on the fourth floor of a building and far from 3 nodes (approximate 150m). I see that only one node can communicate with gateway (it is the nearest node) while others can't do it. I use UART Lora SX1278 433Mhz 3000m EBYTE E32-433T20D which can transmit s data 3000m long. (I have this problem when I test the communication between nodes and gateways at school)
There is a lot of information missing. Did you test this before setting it up? Can you post a simple schematic of each node and the gateway? Links to the hardware items giving technical information will help us help you.

Before testing, I place nodes next to a gateway and I see that they transmit and receive smoothly.
Cant say I am surprised.
Radio communications in buildings can be extremely restricted due to the nature of the walls and floors, which may contain metal sheet or screening.
LoRa modules,by default, may also not be configured for the longest range mode, but no-one knows how you have set yours up.
On the web page of the shop, we bought the modules, they say that using a software to config some parameter of the devices such as baud rate, address, parity, speed, output power.
