PingPong example from I-CUBE-LRWAN software not working on B-L072Z-LRWAN1

As I said in the title, I tried to test the PingPong example avaliable in the I-CUBE-LRWAN software expansion but it does not work on B-L072Z-LRWAN1 board.

After importing the project to SW4STM32 and running it (without doing any modifications), this is what I get in console:

What I see on board is 4 LEDs blinking all the time. If I am not wrong, the PingPong example should send the PING message directly and just turn on the blue LED. However, when I use a UART terminal, this is what I see (in a loop):

0690X0000060RnHQAU.pngThe PING message is not shown (I assume that the board is not even transmitting). When I try to debug the program to investigate the problem I get this error:

0690X0000060RnvQAE.png

I am working with a virtual machine with Windows 10 as host. I updated the ST-Link to the latest version and I am just using one B-L072Z-LRWAN1 board to verify that it transmits a message.

Does anyone have an idea of what is happenning?

You need to make sure not to enable Low Power mode for the build, as this will result in debugger disconnection. Make sure you have the define LOW_POWER_DISABLE

Sorry not using Eclipse or OpenOCD tools

The DISCO board has it's own Ping-Pong build, the examples worked in Keil as I recall, but you might have to adjust the project options/defines to reflect the Radio Band used in your jurisdiction. And the frequencies, bands, and radio settings would need to be coherent across all nodes.

I did it adding '#define DEBUG' in the debug.c file so the debug is enabled for different modes:

void DBG_Init(void)

{

#ifdef DEBUG

 GPIO_InitTypeDef gpioinitstruct = {0};

  

 /* Enable the GPIO_B Clock */

 __HAL_RCC_GPIOB_CLK_ENABLE();

 /* Configure the GPIO pin */  

 gpioinitstruct.Mode  = GPIO_MODE_OUTPUT_PP;

 gpioinitstruct.Pull  = GPIO_PULLUP;

 gpioinitstruct.Speed = GPIO_SPEED_HIGH;

  

 gpioinitstruct.Pin  = (GPIO_PIN_12 | GPIO_PIN_13| GPIO_PIN_14 | GPIO_PIN_15);

 HAL_GPIO_Init(GPIOB, &gpioinitstruct);

 /* Reset debug Pins */

 HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_RESET);

 HAL_GPIO_WritePin(GPIOB, GPIO_PIN_13, GPIO_PIN_RESET);

 HAL_GPIO_WritePin(GPIOB, GPIO_PIN_14, GPIO_PIN_RESET);

 HAL_GPIO_WritePin(GPIOB, GPIO_PIN_15, GPIO_PIN_RESET);

 __HAL_RCC_DBGMCU_CLK_ENABLE( );

 HAL_DBGMCU_EnableDBGSleepMode( );

 HAL_DBGMCU_EnableDBGStopMode( );

 HAL_DBGMCU_EnableDBGStandbyMode( );

  

#else /* DEBUG */

 /* sw interface off*/

 GPIO_InitTypeDef GPIO_InitStructure ={0};

  

 GPIO_InitStructure.Mode  = GPIO_MODE_ANALOG;

 GPIO_InitStructure.Pull  = GPIO_NOPULL;

 GPIO_InitStructure.Pin  = (GPIO_PIN_13 | GPIO_PIN_14);

 __GPIOA_CLK_ENABLE() ;  

 HAL_GPIO_Init(GPIOA, &GPIO_InitStructure);

 __GPIOA_CLK_DISABLE() ;

  

 __HAL_RCC_DBGMCU_CLK_ENABLE( );

 HAL_DBGMCU_DisableDBGSleepMode( );

 HAL_DBGMCU_DisableDBGStopMode( );

 HAL_DBGMCU_DisableDBGStandbyMode( );

 __HAL_RCC_DBGMCU_CLK_DISABLE( );

#endif

}

Thank you so much! The debugger is working now.
