CC2642R: How to debug RF output for a ble device

john Doe

Part Number: CC2642R

Hi,

I'm working on integrating ble peripheral functionality on custom hardware which has a cc2642 chip. I've added the simple peripheral application files to a preexisting project. In my main.c file I can then run the simple_peripheral_task_ create function alongside the previous ICall initializations and the project runs as it should. I then tried to synchronize the ble task with the preexisting project tasks using a semaphore. When doing so the ble task will run but the device does not show up when I try scanning for it.

I wanted to ask how I should go about debugging the RF output and collect the ble traces for the project.

Thanks in advance,

John.

Hi John,

Thank you for reaching out. I have a few questions that will help us get to the bottom of the behavior you are seeing as efficiently as possible. Can you share the SDK version you are using? You mentioned that you are using a custom board, are you observing the same behavior when using a LaunchPad? I would also suggest submitting your design for a design review at SIMPLELINK-2-4GHZ-DESIGN-REVIEWS to allow some of our HW experts to take a look at your schematic and layout to provide some feedback on the design.

Does the unmodified simple_peripheral project work as expected on your custom board? We have a debugging guide available on the documentation that may be helpful here.

Best Regards,

Jan

The unmodified simple_peripheral works correctly, it even works fine with minor changes but when I start to construct the simple_peripheral task and run it alongside other threads its is no longer discoverable.

for this project I am using SDK version 3.10.0.53

Thanks again for the help,

John.

Hi John,

To be able to to view the output for rf I recommend you do the following

https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_6_40_00_13/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/debugging-index.html#debugging

From the information you provided it sounds as though you arent handling the threads properly. I would check if your application is getting help up (try debugging and stepping through your functions to see if and where it fails)

I would also suggest reading through the creating a BLE application section of the user guide.

https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_6_40_00_13/docs/ble5stack/ble_user_guide/html/ble-stack-5.x/the-application.html

Do a sanity check of your threads.

Kind Regards,

Rogelio
