Re: xQueue between cores takes long time

FWIW I have timed queue tx -> rx between cores to be 20us on average in my application (that does not do any heavy processing). Task notify is barely faster. In my case I'm sending from high priority task on Core 1 -> medium priority on Core 0. All wifi / network / sdk tasks are on core 0. Max laten...

Re: Mass mfg: Release efuse config?

Regarding #2: espsecure.py automatically parses whether the .pem file is a private or public key and derives the public key. Perhaps there is a method in espsecure.py for this already but for future reference to anyone with a similar question you can just do openssl rsa -in private_key.pem -pubout >...

Mass mfg: Release efuse config?

For a variety of reasons, we do not want the ESP32 to be self-encrypting during our mfg process. I have identified what I believe to be the right process for generating the flash enc key, flashing the secure boot v2 digest, and then flashing pre-encrypted binaries. But I would like to double check h...

pyBlufi - cross-platform Blufi library in python

I made a python library for Blufi to perform device provisioning from a PC (mac/linux/windows) using BLE. This makes use of the bleak python library. The main reason for this is to be able to speed up development of customizations to Blufi, instead of having to use a phone or simulator. This way you...

Re: ESP-IDF 1.0 Release plan

Just want to give a big CONGRATS to the Espressif team. :D I'm really impressed with everything you guys have compiled into this release, especially so soon after the general release of the chip. Compared to the SDK in the early days of the ESP8266, where even basic things like SPI were not well doc...

Re: ESP-IDF 1.0 Release plan

Well that would be sweet! Also -don't mean hijack, I can't send PMs- I've been experimenting with using AVRNaCl (https://munacl.cryptojedi.org/atmega.shtml) on the ESP8266. With that code it takes 500ms to do a crypto_box_open() running @160MHz. So too long for frequent use. Would your micro-ecc por...

Re: ESP-IDF 1.0 Release plan

Maybe a long-shot, but how about an optimized libsodium for Ed25519, or maybe even with hardware acceleration if that's possible? Probably not for 1.0 since it's less used, but it's becoming more popular.
