Yes.
No. It is the same as with the other products. Any developer with C/C++ knowledge can write libraries. Over time there will be more and more libraries.

This is very appealing. I've a big fan of Arduino and have implemented a lot of automation projects in my home (i.e., automated my blinds w/ an infrared remote control).
In the video, is the communication with the mobile totally over TCP/IP or is there some sort of serial connection? Really that was the most appealing part - the ability to integrate and interface an arduino with mobile apps.
I suspect this would be a lot easier that say b4i or b4a since there's no visual aspect to it.
I think what would be KILLER would be a b4r module that basically turns your Android or iOS device into a virtual shield - all the sensors totally available to your Arduino - OMG, drool

It is a simple TCP/IP connection. The USB cable is only for power (and logging).
About ESP8266, it shouldn't be difficult to support all boards that are supported by the Arduino IDE. Can you post a link to a popular ESP8266 board that can be programmed with Arduino IDE?
Well, there's a lot of ESP Modules (Wiki ESP modules / ESP modules); one of these (that I have) is the ESP-01 module:
What makes the ESP8266 so powerfull is that you can use it like a WIFI shield for Arduino or as standalone device (you can program directly with Arduino IDE).
As the ESP8266 has a fixed number of digital GPIO pins (even analogic pins --> in ESP-01, two GPIO if you're using serial comms but for ex: Wemos D1 mini has 11 digital GPIO and a lot of shields), these can be connected directly to a relay switch, temperature sensor, etc.. and use the several libraries avalaible (mqtt, http, etc..) to interact with this sensors: a real IoT solution
I don't know if at first release, you can include support for the wifi shield and the standalone device but it could be a great solution for B4R and B4X integration
The ESP-01 is the most popular version of the board. It has a printed antenna on-board and a header block for easy access to pin-outs.
- ESP8266 chip.
- 2 dedicated GPIOs.
- Serial comms (or 2 additional GPIOs).
- Pin connectors.
- Arduino-compatible.
- PWM, I2C, UART, OneWire.
- On-board WiFi + printed antenna, 802.11 b/g/n, 360m range.
- Able to become a wireless access point.
- Lua firmware available.
- Able to run a web server.
- Dimensions: 24.75 x 14.5mm.
- Power: 3.3v.

Hi Erel, ESP8266 would be without any doubt the perfect combination to match B4A and B4R. Here is the link of the library for using ESP8266 in Arduino.

Edit: The most wonderfull thing about it is that an ESP8266-01 cost is around $2-3 US.

If you use the ESP8266 as a remote sensor, you can do it very simple by using HttpUtils. Before you have to flash the ESP with this:

Example (using simple get methods to control the gpio/sensor)

But, if you have a Battery powered sensors ? Is 80 ma not too much ? I have sensors with HM-10 (BLE ), powered by 180 mA battery.
Unbelievable a basic interpreter for the ESP8266. This remember me good old Basic Stamp time. I can't wait to give it a try.
I hope to release a first 'alpha' version in a few weeks.
I bought 3 of them because of the very low price. When I got more time I will check it
Wow
well I can't wait! I'm a huge Arudino fan. So much can be done with it. It will be very valuable to use regex, maps, lists, and objects in generally in that environment.
There are very hard limits on what can be done in less than 2000 bytes of RAM.
There is no magic.
Regex is out of the question.
B4R will not use dynamic memory at all. I will post more information about this when B4R will be released. However it means that lists and maps will also won't be implemented, at least not in the first version.
