Hello,

How can we turn off the debug messages which are coming out of the TX_DBG pin of the CC2564C?

The messages coming out of this UART are a security issue.

Thank you and best regards,

Hi Ambroise,

I will check if it is possible to disable these messages. However, I don't think these messages are easily accessible without a direct connection to the TX_DBG pin on the CC256xCQFN-EM's P2 header.

Thanks,
Jacob

Hi Ambroise,

Unfortunately, you cannot turn off these messages. The customer should leave the TX_DBG pin as a test point and not directly connect it. It is always good to have a way to test the device in case there are issues later on.

Thanks,
Jacob
