Radiolib 7.7 example LoRaWAN_ABP
Esp32 wroom32 or ESP32c3 supermini, sx1276, ChirpStack
Log:
Setup ...
Initialise the radio
Initialise LoRaWAN Network credentials
Ready!

Sending uplink
No downlink received
Next uplink in 300 seconds

What is wrong?

I see no error, what makes you think something is wrong?

[581225]

My device with arduino code example LoRaWAN_ABP from library did not connect to Chirpstack. I can't see my device even on the gateway Chirpstack with region eu868. At the LMIC library all OK

[StevenCellist]

Well, what did you try to find the problem? Did you try the Debug mode that is built into RadioLib?

[581225]

Should I include these lines in the examle sketch:
#define RADIOLIB_DEBUG_BASIC
#define RADIOLIB_DEBUG_PROTOCOL
#define RADIOLIB_DEBUG_LORAWAN?

[581225]

But when compiling the sketch I get errors: In file included from /home/victor/Arduino/libraries/RadioLib/src/TypeDef.h:6,

Sorry, I was wrong. You need to enable it.
#define RADIOLIB_DEBUG_BASIC (1) // basic debugging (e.g. reporting GPIO timeouts or module not being found)
#define RADIOLIB_DEBUG_PROTOCOL (1) // protocol information (e.g. LoRaWAN internal information)
#define RADIOLIB_DEBUG_SPI (1) // verbose transcription of all SPI communication - produces large debug logs!

[StevenCellist]

You got it. Just don't enable the SPI log because that is insanely overkill. Basic and protocol should be more than enough!

[581225]

I've been debugging and got the same thing:

Sending uplink
No downlink received

No debug logs at all. I'm sad. It all seemed simple to me. I took a simple example from the library, compiled it in Arduino, and then uploaded it to the device. But nothing works.

[StevenCellist]

For the Arduino IDE, it is much safer to enable these #defines in the file Documents/Arduino/libraries/RadioLib/src/BuildOptUser.h (the exact location depends on your own system, but typically it can be found at that location). Please try that instead of defining these in your example sketch.

The example is simple, but LoRaWAN unfortunately isn't that simple. There is a lot that can happen, which may already start with re-using FCnt values. Your device may be transmitting, but if the frame counter value is re-used, you won't see anything in the LoRaWAN frames tab, although it should appear in the Events tab with errors. But that's only one of the many things that may be different than expected.
