> any update @Kongduino ? I wasn't aware I was supposed to follow up on this... My answer is as complete as can be, given the circumstances.

Here's [an article about CAD](https://lora-developers.semtech.com/documentation/tech-papers-and-guides/channel-activity-detection-ensuring-your-lora-packets-are-sent/how-to-ensure-your-lora-packets-are-sent-properly) from the Semtech website. It's quite technical but explains CAD quite well – and it's from the horse's mouth, so to speak.

You don't set SF, BW, CR parameters, so they could be different on both devices.

You could do what LoRaWAN does, ie use different frequencies for sending and receiving. You keep everything else the same.

You should use CAD (Channel Activity Detection) to make sure that the other sender isn't already transmitting: what you are seeing is most probably interferences between both senders, which are...

Oh thanks I wasn't aware (OBVIOUSLY!)... How could I help with testing?

I have but they don't concern transmission. I use mostly ESP32 boards with LoRa sx1276 (sometimes stm32 boards too), and RAK boards (nRF52 or STM32) with sx1262. No issues whatsoever....

You provided photos and a connection diagram, which is nice. So many people forget lol. But the code would be nice too!
