Your LoRa init code should stay in `setup()`. Code in `loop()` is repeated continuously and is for when things have been set up (*chuckle*) and are working smoothly. Put the...

@IoTThinks's comment about high packet loss was maybe a little cryptic, but not random. In your code you added the transmitter code, commented out, for reference. Of course since it's...

Please format your code properly. Not 1 ` but 3, before and after the code. Like this: ``` void setup() { // put your setup code here, to run once:...

First thing I can is this: `SDA_OLED` and `SCL_OLED` are not defined anywhere, and the error message is complaining about `Can't init sda=1, scl=1`. Can you try the init code...

Indeed I have the same boards, bought them a long time ago. So I went dumpster diving and found some old code. I init the OLED like this: ```c SSD1306...

What are the radio settings of the SX1278? Frequency, SF/BW etc... These are important.

What's your preamble length? It's 8 by default, which would account for the extra 8 bytes.

It seems we have the same question popping up regularly here.1. Leave the pins alone. Do not try to set them up yourself.2. Your Arduino Uno is 5v. Your sx1278...

Hi again. It's not so much a problem of compatibility with the Arduino Uno itself – it's the 5V. I have a Chinese Arduino Uno clone that can be switched...

Yes. You need to set up `RegIrqFlagsMask`'s (0x11) bit 0 – `CadDetectedMask` – to set up Channel Activity Detection, and use `RegIrqFlags`'s (0x12) bits 0 (`CadDetected`) and 2 (`CadDone`) to...
