#1

hi
I check the example in ESP32 repo:

and it doesnt build:

vscode shows errors:

any advices?

#2

Are you compiling for a V3 board or a pre-V3 board? This code looks like it’s intended for a pre-V3 board, which uses the SX1276 LoRa chip (and the LoRa library), rather than the V3 boards, which use the SX1262 LoRa chip (and the Radio library).

#3

actually I wanted to run this code on HTCC-AB02…

I saw that this example uses “LoRaWan_APP.h” module:

and thought that it is possible to run it on CubeCell device…

but now I realized that this module probably should come from this repo:

my VSCode+PlatformIO used some own LoRaWan_APP.h file and it seems change everything…
total mess…

#4

The WiFi_Kit_series is also based on the ESP32, so that probably won’t work either. You should probably be looking somewhere like:

it seems that LoRa library works in different way from Radio library.

“LoRa” lib allows to prepare LoRa packet with LoRa.beginPacket() method which declared in the LoRa.h module, and this allows make addresses for nodes.

But in the “Radio lib” for CubeCell (radio/radio.h) - there no similar method to do same thing…
