All things about Espressif's ESP8266 Internet of Things [IoT]

greetings!,

in conjunction to my https://www.istorya.net/forums/compu...ino-atmel.html here, I would like to ask fellow istoryans nga na-a experience ani nila. I really like to term them little WONDER modules/devices for IoT!

this chip came to my mind when blaklist25 commented

esp8266 wifi module boss.. 100 petot equivalent.. serial interface pwedi ra sab standalone

dugang raka 100 dina kailangan nimo arduino kadtong daghan pins na module imo paliton..

great thing ani nila kai daghan ka-ayo projects and good thing kai kasagaran kai stand alone modules!

so..., post/share your experience with these great chip!

I've used a few of these ESP-01 modules for wifi connectivity. Built libraries for STM32 MCU's that will talk to these ESP8266 chips via AT commands for TCP/IP connectivity. Built a BSD socket emulation layer on top of the AT api, you can find the source code from here https://github.com/vpcola/MikroChibiOS

Lately I have been using the more complete NodeMCU platform, but using the RTOS based SDK/GCC toolchain for my mini-projects (home automation, weather station). It was fun to use the ESP8266, but this micro-controller has some flaws.

- While there is a built-in AES and the chip can also connect to HTTPS servers, TLS and AES-256 is still a long way to go. In contrast, my LPC1768 microcontroller, although has no wifi (but has an Ethernet MAC), is capable of connecting via TLS using wolfSSL.

- The Xtensa LX106 is a power hungry MCU - compared to other ARM Cortex M0 or L0 variants, this chip eats a lot of power. I don't normally use these on battery powered devices. I think the Espressif manufacturer is releasing a newer version of this chip to address this issue.

I would have used this primarily on my hobby projects, but this is not for me, again for the reason stated above. These days, I'm using TI's CC3200 chip, its better in all terms, except for the cost.

nigawas na ang ESP-32 dual core nila, around 6 usd ang module it'll go down in a few months when production ramps up and other chinese manufacturer's makes there own module version.

wifi+BLE, dual core... firmware will be running with FreeRtos. Joined a workshop a last month man tali to..
