    Hello Kevin,

    When you say detect mode, do you mean receive mode? Can you explain what detect mode is and how you put the device in this mode?

    Also what is OTP mode? How is this a failure for the device?

    Lastly, after the CC2340 is placed in the oven and fails, does the device recover and operate as expected when taken out of the oven and placed at room temperature? 

    Providing information to the questions above will help us provide you with some suggestions as to what might be the issue. Thanks.

    Kevin,

    Can you measure the current consumption of the device when it is failing at 125C? If so, please provide the measured current consumption. Thanks.
