CC1310: Miss Rx Packet in Normal Run, but don't miss in debug mode

Trung Nguyen67

Part Number: CC1310

Helllo everybody

Now I have a problem with my custom board.

My code works well with CC1310 LaunchPad, but not well with my custom board.

My custom board receives Rx packets very well in Debug Mode in CCS. But when it runs normal, it miss Rx packets so many times.

My custom board also works very well with SmartRF Studio, it shows that the antena is good.

Does anyone know why?

Here is my schematic and my project in attach

Thanks you so much for your reading.

Hey Trung,

If you're code works with a LaunchPad, the issue may be from your board design. I'll review your schematic (and code if needed) and provide feedback within 4 days.

Please make sure that my board design works very well in Debug mode in CCS, and it also works very well with SmartRF Studio to Tx and Rx

I'm really looking forward to hearing your feedback.

Hey Trung,

Are you implementing any low power modes in your application?

In addition to my last question, when your custom board is in debug mode you are powering and communicating using a USB. Are you powering your custom board with the same USB cable when it is running normally and missing RX packets?

Trung,

Have you found any luck with resolving this issue?

Revisiting this again, I am assuming that when your custom board is running in debug mode, you are triggering the packet TX and RX. And when in normal mode, packets are being transmitted back to back. It may be missing Rx packets as the transmission rate is too fast.

How many packets per second are you transmitting? Have you tried decreasing the Tx rate?

No, now I just run my app in normal.

Yes. I'm powering it with the same USB cable.

I just test with the RF packet Tx and Rx example for my custom board. I use the defaut rate is 500ms.

Actually, my team have decided to choose the module CC1310 that other company makes it for the reliability of my custom board.

I hope I can get your help if I need from you in the future.

Thanks you for your help, Seong Kim.
