SDK 4.10.

A customer reported that, when using Simple Peripheral using HeapMem (HEAPMGR_CONFIG = 0x01 or HEAPMGR_CONFIG = 0x81), instead of the default (OSAL), some things stop working.

For example, HCI_RESET command does not respond with a HCI_CommandCompleteEvent, but it timeouts instead.

I was able to reproduce the issue by doing the following:

Working scenario:

1) Use  CC26x2 LaunchPad with out-of-the-box simple_peripheral example

2) Connect to the LP using BTool

3) Send HCI_Reset command (from the Advanced menu)

4) The LP responds with  HCI_CommandCompleteEvent

Error:

1) Use  CC26x2 LaunchPad with a modified simple_peripheral example, where HEAPMGR_CONFIG = 0x81 on the simple_peripheral_app.cfg file

2) Connect to the LP using BTool

3) Send HCI_Reset command (from the Advanced menu)

4) The LP does not respond and a timeout occurs.
