I am asking you to create a new DevZone thread.

Initially, I called xPortGetFreeHeapSize() and found that there was insufficient space, so I changed the value of configTOTAL_HEAP_SIZE. I found that this value cannot be increased by a lot, and can only be increased by a small amount above 4096.

This has nothing to do with threads. I can create and run threads without any issues.

But，When I increased the value of configTOTAL_HEAP_SIZE, all my log information disappeared.

Please make a new thread as this is likely not related to the original topic in this thread.

Could this be related to the burning of the Bluetooth protocol stack into the device?

When I was debugging just now, I found that the value of configTOTAL_HEAP_SIZE could be increased from 4096 to 4420, but not further. The program would get stuck at this statement during debugging. I am a beginner and do not understand assembly language. 0x0002528C 9906 LDR r1,[sp,#0x18]

I don't know, we need more information. But please make a new thread for it and explain more what you are using, what you have changed, how you are testing and what you have found from debugging

Why does the program stop running after changing the value of configTOTAL_HEAP_SIZE from 4096 to 8192? Before the change, there was not enough space.

Hi,

There is not enough information here to make any suggestions. Please describe in detail what you do and which error you get where. If it is not directly related to the original question I suggest you do so in a new question.

Hi,

That was strange. Increasing the total heap size in the projects FreeRTOSConfig.h (under <SDK>\examples\ble_peripheral\ble_app_hrs_freertos\config\) fixes this on my side.

You can compare with this modified HRS example from SDK 15.0.0 which adds an additional dummy task based on your question.
