I'm going back to this topic because this problem occurs more and more often (I see several similar reports even outside this forum) and so far no one has indicated a possible recovery solution or at least a procedure that works to rewrite the entire flash (reverting to factory default)...

Hi,
I have the same issue here:

The same works fine on v4.2 release as well (ESP-IDF Github head: c40f2590bf759ff60ef122afa79b4ec04e7633d2 esp-nimble head: 95bd8644abf4a410dd3fb914468d3a23ac9bbec2 nimble-1.2.0-idf branch) Logs:

Hello @ESP_Hrishi,

I'm on TAG" v4.2" ( https://github.com/espressif/esp-idf/tree/v4.2/ ) not branch "release/v4.2":

I guess the correct way is to use the TAG which is associated to stable and "verified" version.

Anyway I will try to update submodule "nimble" to the commit you specifed.


Thanks!

@davdav

You don't need to file an issue. It is now tracked internally.

Quick fix: Can you please add the following line (in green) below ble_npl_callout_stop in the file esp-idf/components/bt/host/nimble/nimble/nimble/host/src/ble_hs_stop.c:

ble_npl_callout_stop(&ble_hs_stop_terminate_tmo ...

@davdav

Thank you for reporting the issue and for providing a simplistic code to recreate the same. Yes, this looks like a problem.
Just to give you some background, the NimBLE upstream does not yet have the stop/deinit support integrated. We have added this functionality to our port (esp-nimble ...

Hi everybody,

I'm trying to port our application which used Bluedroid to nimBLE. I'm working with esp-idf-v4.2.

In my opinion there is a memory leak when nimble is init and deinit if GAP advertizing is used.

I have written a simple code to test it (derived from "bleprph" example). Please find ...

libmbedtls.a also decreased by that amount.

Total image size:~1650794 bytes (.bin may be padded larger) 1598298 +52496

So you are down to around 50k which is probably expected for new features. A 3% increase.

Thanks @WiFive. That's OK to have 3% of increase.

Have a look at this too:

Thanks @boarchuz. I have checked difference and, although there is an increase in some of my source code(this is strange but could be related to change from "tcpip_adpater" to "esp-netif"? ), the main and relevant difference ...

idf.py size-components should give you more info

Thanks @WiFive. I have worked on menuconfig and removed some BLE features (in particular debug to save .bin size), so now I have a difference of 100KB. Below is size-components:
