Problems initializing Zigbee S2C with STM board.

Hi Everyone,

I'm running into some problems with initializing a Digi XBee S2C with a NucleoF103RB board.

Currently I'm using the XBeeLib_Fixed from Lorenzo Maiorfi, though I've used Digi's official library as well.

I have my XBee connected to UART 2 (D0/D1) with the reset connected into D2.

Pinout to the F103 Board: https://os.mbed.com/platforms/ST-Nucleo-F103RB/

When I try to initialize Zigbee, it returns a fail and I can't for the life of me get it past the XBeeZB.init(); step.

I've configured my Zigbee through XCTU with API mode set to [1] as a coordinator, SM is set to [0]; It's currently flashed with function set "ZigBee TH Reg" on firmware version 4060.

Here is my code:

#include "mbed.h"
#include "XBeeLib.h"

using namespace XBeeLib;

Serial PC(USBTX, USBRX);

int main()
{
    XBeeZB xbee = XBeeZB(PA_2, PA_3);
    RadioStatus const init = xbee.init();
    if(init != Success){
        PC.printf("Zigbee could not be initialized properly, check pins!\r\n\r\n");
        }
    else
        PC.printf("Zigbee Successfully Initialized\r\n\r\n");

    wait(1);
    RadioStatus const reset = xbee.hardware_reset();
    if(reset != Success){
        PC.printf("Device was not successfully reset, check your reset pin\r\n\r\n");
        }
    else
        PC.printf("Successfully Reset XBee Device");
}

and the important parts of the config.h file

#define RADIO_TX D1
#define RADIO_RX D0
#define RADIO_RESET D2
#define DEBUG_TX USBTX
#define DEBUG_RX USBRX

EDIT: I realize that my code has a const condition for RadioStatus, however it does not initialize even if I remove the const before init and reset.

Pins:

Zigbee -->F103RB

Pin 1 (VCC)-> 3.3v

Pin2 (TX)-> D0 (RX)

Pin3(RX)-> D1(TX)

Pin5(RST)-> D2(GPIO)

Pin 10(GND)-> GND

If I'm missing any information, please feel free to mention it.

Thanks all!
