Espressif announced on 05/11/2015 the upcoming ESP32 chip: While the specs are impressive a lot of questions a rise : Support – Espressif is a small company as far as we knew – would they be able to support both chips in the long term? Compatibility with esp8266? – The new ESP32 will use the RTOS based SDK and most APIs are said to be compatible with the esp8266 SDK.

While working on a secure cloud for the gang of the esp8266 based devices we are developing we need SSL – real and secure. And this August is the month of the SSL issues , it seems , but thankful to the Espressifs’ quick support they are on the way out. SSL Memory Leak The latest SDK v1.3.0 introduced a bug that simply didn’t call the disconnect callback of esp connections under some circumstances and that in turn leaked memory.
Hi, I have signed the IoT Design Manifesto – if you are into IoT. You should too. Here is the link Sign The Manifesto. These are the highlights of it: We do not belive the hype! We design useful things! We aim for the win-win-win! We keep everyone and everything secure! We build and promote a culture of privacy! We are deliberate of what data we collect! We make the parties associated with an IoT product Explicit!
Engineering Internet Of Things Secure network for our upcoming IoT service. Goals: Security Redundancy End to End Security Secure Firmware Upgrades Threats: DoS Attacks DDoS Attacks DNS spoofing /don’t even think of DynDNS/ Sniffing man in the middle Security: Using a VPN -> takes the problem away and requires extra settup. Not user friendly. The only pro is that it can use an existing infrastructure if present.
I need a bigger flash and a breadboard friendly board. Quick research lead to the following variants, beside soldering a bigger flash on the ESP-XX series modules. NodeMCU board’s that have bigger flash and fit on a breadboard but have regulators and usb 2 serial on them. ESP-XX module with adapter, don’t like . MOD-WIFI-ESP8266-DEV And the winner is Olimex’s – MOD-WIFI-ESP8266-DEV . i got some of them:

Current focus is on the Internet Of Things hype. Why call it a hype? A lot of people were doing it for the past decades – just like anything that gets conquered by the internet. So now is time to connect it. What to connect: Your Door Bell Your presence at every room Your fridge Your car Your house Your appliances Your …. dog ?
