RTOS/CC2640R2F: Connecting issue, after porting project with cc2650 to cc2640r2f

Part Number: CC2640R2F

Tool/software: TI-RTOS

I'm porting our project (based on project_zero) and now I have problems with connecting to our device.

Log from device below:

I have absolutely no idea how I should debug it. Can anyone give me advice?

Hi Roman,

After looking at the log, it appears that your device never responds to the LL_Connect_Update_Req sent by your master - try to revert back to the old L2CAP Connection Update Procedure. (Or disable this on your central side) For an example of how to turn off this feature take a look at the simple_peripheral example in the latest SDK and look for the USE_LL_CONN_PARAM_UPDATE define.

This should automatically be handled by the application, what modifications did you make to Project Zero?

Regards,
Rebel

Hi, A. Rebel

Thanks for your reply. I noticed that my problems arose when I added / deleted tasks. I can't imagine why this happens, but it seems I found a simple solution to the problem: I need to clear the project_zero_cc2640r2lp_stack_library before the assembly. I'm sorry if my question was stupid.

Regards,

Roman

Hi Roman,

It's possible that the some task's stack may have been overflown - just be careful when adding/removing tasks, and use the ROV viewer to verify that everything is still running smoothly:

The sniffer log definitely helped out - I'm glad you were able to figure out your issue!
