Re: Private unique id?

The MAC adresses could be used as the base of a larger UUID, by multiplying it with another fixed large number? This would definitely make it less obvious as to where the UUID originates. However yes, this would be reasonably easy to figure out for someone who really wants to get into your system. A...

Re: Espressif Response to BlueBorne Vulnerability?

(Note: I am not a security researcher, or an espressif employee) From my understanding of the attacks so far: The vulnerabilities that relate to the exploitation of the BNEP service, and also the PAN profile of this service would not seem to affect the ESP32. As far as I can tell the ESP32 stack doe...

Re: Compile error with Compiler options - Optimization Level (Release (-Os))

Hi Angus, Thanks for the reply. I look forward to seeing this change making its way back into the github master. Thanks for the suggestion re: assersions. So to confirm, you suggest: For debugging: Enable all assertions For testing (some debugging): enable silent assertions For release: disable asse...

Re: What would you like to see in The Next Chip?

Great to see you are looking for feedback from your user base! I would like to see: - USB FS(12M) Device/Host. (HS, 480M, with internal phy if possible!) - 5Ghz WiFi, prefferably wifi AC (i know you are already working on 5GHz which is great!) - A package with a larger pin count, eg 48 or 64 pins. -...

Re: Compile error with Compiler options - Optimization Level (Release (-Os))

Hi all, We have run into this issue before. It seems to be related to (kind of recent) setting Copmpiler options --> Assertion level When this value is set to Disabled (an hence disables the asserts at the bottom of the offending functions), those two functions in the nghttp lib warn that there is a...

Re: BLE multi-connection procedure

Hi Weijian,

Thanks for the example. This confirms that what I have implemented is very close to what you have in the example!

Re: Power Saving via menuconfig?

I believe there will be power saving features baked into the upcoming v3.0 release of the idf.
So this doesnt really help you now. but hopefully in the future power-saving will be a more automated feature.

Custom module flash speed limitation

Hi All, We have designed an ESP32 module. We are currently going through some testing and have found that the chip will fail to boot properly if the SPI flash speed is set to anything above 20MHz. The module fails on boot with the error detected as "rst:0x10 (RTCWDT_RTC_RESET),boot:0x17 (SPI_FAST_FL...

Re: BLE Low Power Mode

Hi Abhiram,

This feature is currently not implemented.
I believe it is currently being worked on for the v3.0 release, but I could be wrong.

vTaskGetRunTimeStats Support

Hi all, Just wondering if vTaskGetRunTimeStats is supported with the current esp-idf? I see that is is in the version of freeRTOS that is used in the idf. However I don't think all the required options are enabled. I also don't think the higher resolution timer required for this is setup, at least i...
