RTOS/CC2640R2F: Heap memory issue while connecting IOS and android APP.

Part Number: CC2640R2F

Tool/software: TI-RTOS

Hi,

Stack used : v3.1.1 (SDK version 1.50.58)

Device : CC2640R2F.

Testing App : nRF Connect (Nordic semiconductor).

In my project i have 4 services with Bonding and Encryption enabled and 2 services having Extended MTU size of 65bytes.

If I use iOS and android phones as central device, the heap memory usage is more during the connection time (bonding+connection) (6K approx).

But if i use the launch pad with Host test program as a central device , the heap memory usage is very less during the connection time(bonding+connection) (approx 3.8K).

Since i am using the same peripherals device, why the Heap memory consumption is more for iOS and android phone?

Please provide some suggestions.

Thanks and Regards,

Hello,

This could be related to privacy. The mobile devices will be using an RPA and be in the Resolving List.

Could you try configuring the host_test device to use an RPA? With btool and GAP_ConfigDeviceAddr:

And re-run your test. Please let us know your results.

Thanks,

David

Hi David,
After configured the GAP_ConfigDeviceAddr with Peripherals address, Central (launch pad) is behaving same , it is not taking any Extra Heap memory .
Thanks

Hi Jayachandran R,

Ok, another thing we could try, is to disable the DLE feature. Maybe the DLE feature getting used and drawing down the heap due to large RX PDU buffer allocations.

Please let me know if that makes any difference.

Thanks,

David
