WB05KN vs WB05KZ, custom firmware

Dadigno

Hi everyone,

I'm working with the WB05KN because I’d like to take advantage of the option to have the firmware preloaded during production.
However, I also want to make sure that I’ll be able to load a custom firmware in the future. Is this possible?

I tried flashing the BLE_TransparentMode_SPI and BLE_TransparentMode firmwares from the examples for NUCLEO_WB05KZ, but without success — the firmware gets stuck inside SystemClock_Config.

 

  if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    Error_Handler();
  }

 

 I understand that the two components have different part numbers, but my understanding is that the only difference is the pre-flashed firmware — or is there something else that differentiates them?
