ERROR 12290 [Unknown error code] at (null):0

Hello,

  Please check this code for BLE disconnection.When peripheral tries to disconnect from the central , it is disconnect successfully the first time but second time it gives an unknown error and   the  whole controller resets.Please do reply to this.

Thanks & Regards,
