on Nucleo L476RG D0 and D1 are not connected by default:

SB 62/63 are opened by default as PA2 and PA3 are used by the STLink.

So that's the reason it didn't work before?

you dont get the message on the sigfox backend? are you sure the module its connected to the right Tx and Rx pins? your modules have leds to let you know when its transmitting?
also, you are using the wisol.send_rcv() funtion, if you dont have a downlink configured use wisol.send()


I ...

in your module you have a reset pin beside the Vcc pin (marked in blue in the graphic). connect that to the nucleo board on some free pin.
this pin its necessary to wake up the module after its put in sleep mode
load the code and push the user button.

I tried with several different ...

try this configuration:

HardwareSerial Serial3(USART3); //connect the modulo to serial3.
Tiny<HardwareSerial,HardwareSerial> wisol(&Serial3,&Serial,PA1,false); //change PA1 to match your reset pin.
.
.
.
#define btn PC13 //change this to PC13 the blue/user button on the nucleo
#define RXLED PA5 ...

a friend and i wrote a library for the wisol modules. we call it TinyFox. the blue pill example should be compatible with minimal modifications
you can find it here: https://github.com/TECA-IOT/Tinyfox
or at the library manager : )

just change
HardwareSerial Serial2(USART2); //this is the default ...

Try to disable the USB CDC as the Nucleo L476RG as no USB connector maybe the clock for USB is not properly configured.

Edit:
I've tested with USB enabled and it's failed due to clock init.
This will be fixed in the variant rework anyway simply disable USB as it is not required or redefine the ...

Could you shared all your config?
core version, Arduino IDE version, selected options...

Could you try to update the STLink FW?

I updated the firmware to version V2.J37.M26 using STM32 ST-LINK Utility, verified and uploaded the compiled code, but the problem persists.

I followed the getting started guide , selected the Mass Storage upload option ( since Nucleo boards integrate a ST-Link ), verified and uploaded blink example , but the LED doesn't blink. It works using the Mbed compiler. What am I missing or doing wrong? This is just for testing purposes.
