SX1278 Connectivity Issue

Using Arduino Networking, Protocols, and Devices
1

Hello Everyone!

I'm using two SX1278 Lo-Ra modules with Arduino, an UNO for transmitting and a Nano for receiving. The issue I'm facing is, When the transmitter initializes, the receiver fails to initialize, and vice versa. At one point, the transmitter started sending data, but the receiver couldn't receive it. Both modules are powered by their respective Arduinos, with the same frequency and settings configured. Wiring has been double-checked.

Has anyone faced this issue or have any suggestions for a fix? Thanks!

You posted in the uncategorised section where the description specifically says do not post here.

So I have moved your post here.

Please be more carful where you post in future.

How are the controllers powered?
It's a general rule not to use the controller as power supply.

The 'initialization' of a LoRa module does not depend on another LoRa module being present or nearby.

Post a schematic of your connections, details of the modules being used and your code for 'transmitter' and 'receiver'.

Post a complete schematic, showing the required logic level shifters.

which specific SX1278 lora modules are you using?
which LoRa library?
SX1278 module interfaces generally use 3.3V logic - take care interfacing to microcontrollers which use 5V logic
