Arduino for STM32

Following the HardwareSerial example on the Wiki, I commented out SoftwareSerial and added:

HardwareSerial Serial1(PA10, PA9);

And changed lteSerial to:

if ( lte.begin(Serial1, 9600) ) {
Serial.println(F("LTE Shield connected!"));
}
Serial.println(F("Type a message. Send a Newline (\\n) to ...

Thanks for the reply.

Yes, LTE_SHIELD_SOFTWARE_SERIAL_ENABLED was defined. I added that to make sure as seen 1st line in 2nd code snippet.

Thanks for the link. I will give HardwareSerial a try. The problem there is I will have to jumper into the shield versus plugging it into the Arduino ...

I'm planning to use the Sparkfun LTE Shield on a Nucleo 64 board (Nucleo F401RE). I've installed the Sparkfun library and I am attempting to compile their SMS_Send example. This compiles fine for an Arduino Uno. When I try to compile for the Nucleo board, I'm getting an undefined reference during ...
