Hi, Renzo. Thank you for the advice I’ll do exactly that, external 5V to Ebyte 32. and the logic still remains 3.3v so it won’t burn my esp32 right? ok, I’ll do it.
Hi, Renzo thank you for the reply, and I hope you get well soon. as you said it is the wire problem (again) and I think maybe some power problem too? I think that this device consumes a lot of power for esp32 size. it has worked now perfectly smooth. thankyou very much. ill try to power this device through an external source with 3.3v. I hope it can reach at least 1KM. once again thank you
Hi Renzo, can you help me out?
it worked for two-way communication I have figured it out. but still, sometimes I get the same problem but this time I can tell that the problem is only after the library tells me “timeout !!” and then the guru meditation error start. and the time out is always after the second message and my receiver don’t get any data even when the status said the success.I will really appreciate for your help.
starting when I want this lora to be two-way communication. at first, it was all just fine and then this happen when trying two-way communication and now it just continues to do that. but the two-way communication work if the error code not happening. when I unplug Lora there is no error code I try to switch the lora but it does the same.
Yes, I always get this error.

hi Renzo Mischianti. thank you for the replies, I’m currently building peer-to-peer communication for esp32 using Lora EBYTE e32 900T20D. I can’t find a way to make them talk to each other. like it only works for one-way communication, the other one cannot be a transceiver after it becomes a receiver. can you give me an example code for peer-to-peer communication for fixed transmission? it would be very useful. thank you
I’m using LoRa to help fishermen in my area to manage and handle their Fish Aggregating Devices. which is why I need two-way communication.
