CC2642R: Device getting hang randomly while sending data

aditya jadoun

Part Number: CC2642R

Hi,

I am using simplelink_cc26x2_sdk_2_30_00_34 simpleperipheral example. As per my use case i am getting some data from UART and sending that data through notification to connected phones. But sometimes firmware getting hang randomly. After some debugging, i checked device is going in HWI exceptional handler when hang occured.

Can someone please suggest, how to debug this issue and find the cause of hang? Is there any register or API, i can use to get exactly where my code getting hang?

Hi Aditya,

The 2.30 SDK is for pre-release CC26x2R ICs. Neither the SDK nor the IC revision is supported any more. You must update to release version IC and use the latest SDK.

I assume you are not running on the same IC?

Hi Fredrik,

Yes I am aware of that with SDK V2.30 i was using Rev. C IC and now i have checked with Rev.E IC with SDKV3.20. I am getting same issues with both sdk.
