CC2340R5: CC2340R5 : LP_EM_CC2340

Part Number: CC2340R5

Hi 

Im working with Basic_BLE peripheral code. In the code Im implementing API commands .After a while of constant transmission and reception of data from the module, Im observing UART hang issue. Can anyone help me where Im doing wrong in the code. Im using simplelink_lowpower_f3_sdk_7_10_00_35 sdk for my application. 

  • Hi Krishna,

    Could you please provide more details on the "UART hang issue" you are referring to? What are the symptoms? Is the rest of the system still properly working?

    In order to identify the issue, I would recommend to run the following tests:

    - check whether the issue could be caused by a memory leak by monitoring the memory usage of the task (see debugging guide)

    - check whether the issue can be triggered by the reception/transmission of a specific UART packet

    I hope this will help,

    Best regards,

  • Sorry for not proving the further details. Yes , the device itself is going to an unknown state , it is not advertising. It requires a power restart to function again. 

    Can you explain your second suggestion ? 

  • Hi,

    check whether the issue can be triggered by the reception/transmission of a specific UART packet

    I wanted to be sure the issue is not caused by overflowing the reception or transmission UART buffers.

    Regards,
