Bluenrg-2 BCN002-V1 cannot be recovered after mass erase

[meba]

Hi,

 

I am starting to learn and use  Bluenrg-2 BCN002-V1 and tried to flash it using the example provided in stsw-bluetile-dk and Nucleo-F411RE. When trying to flash examples, I performed a mass erase and I cannot recover the board anymore i.e. the BCN002 board cannot be detected by ST RF application anymore, there is a constant green LED instead of blue light. Could it be that I have to flash something like bootloader or Ble stack before flashing the example application binaries? Could you please support me to solve this issue?

 

Best regards,

Mehrdad
