NVM DATA RESTORED not working with STM32WLE5xB (fix included)

[Yoshi20]

I discovered that NVM_DATA_RESTORED is never shown after the context was saved (AT+CS) when using the AT slave firmware from STM32CubeWL_V1.3.0 on a STM32WLE5CB.

After (too many) hours, I discovered that in LoRaWAN/App/lora_at.c the LORAWAN_NVM_BASE_ADDRESS define is wrong for this microcontroller.

Workaround:

#define LORAWAN_NVM_BASE_ADDRESS                    ((void *)0x0803F000UL)

/* USER CODE BEGIN PD */
#undef LORAWAN_NVM_BASE_ADDRESS
// fix bug from ST => define addr 124k and not 252k for this uC (with 128k flash)
#define LORAWAN_NVM_BASE_ADDRESS                    ((void *)0x0801F000UL)
/* USER CODE END PD */
