CC2640R2F: Question about TASK_STACK_SIZE

Part Number: CC2640R2F


Hi

My SDK is CC2640R2 1.30 and my project is base on the simple_peripheral_oad_offchip project.

I found a strong question about CC2640R2F's program. When I used the default TASK_STACK_SIZE  644 for my project, my broad could connected all smartphone stable. Of  course, if I add on more function to the task, it will be Instability.

When I add the TASK_STACK_SIZE to 1024, the task being stable for all add on function. But it couldn't connected a lots of smartphone, such as iphone7, Xiaomi note4 and so on.

I already check the documents such as SYS/BIOS (TI-RTOS Kernel) v6.50 User's Guide and Bluetooth Low Energy Software Developer’s Guide, but these didn't describe any informations about this. Can you tell me the relate about TASK_STACK_SIZE and the task's stable, or how to set the TASK_STACK_SIZE ?

Thank you~

  • Hello Kane,

    Do you have connectivity problems with the mentioned phones if you do not make any changes to the project? Do you see any issues if you use the ROV to Scan for BIOS errors?
