DeviceHive ESP8266 Firmware

Special firmware to use ESP8266 as a local web server with RESTful API and as a client of DeviceHive cloud. This repo consists of a few parts which can be used with other projects. Each project has dedicated readme file.

Photo above is a real photo of the demo device contructed with esp8266. See YouTube video.

Custom firmwares

There is a possibility to build custom firmware on top of this which sends some notifications to DeviceHive server periodically. In pauses firmware goes to deep sleep mode. Reimplement custom_firmware_request() method in custom_firmware.c file with reading of some sensors data. There are implementation for some sensors in sources/devices dir. Also, it is possible to create interaction with any sensor using interface implementation modules (dh/i2c, dh/spi, dh/onewire etc). See climate branch as an example.

Directory content

esp-utils

Simple utils for flashing and connecting to ESP8266.

examples-cloud

Simple web pages with JavaScript sample of sendind and receiving commands from device via cloud. Onewire DS18B20 examples use 0x33[SKIP ROM] command which means that examples work only with one currently connected device. Some browsers (for example Firefox) block cross domen requests even for local file. Allow temporary cross domain requests in setting or use another browser to run examples.

Local RESTful API samples are embedded to firmware. Sources of them can be found at firmware-src/pages directory.

firmware-src

Sources of DeviceHive ESP8266 firmware.

firmware-src/genbin.sh

Small utils which is written on bash and can be used on any OS. This util creates binary firmware files from crosstool-NG binary file output.

firmware-tests

Tests for firmware. You can find command samples in file requests.html. Each addtest() instance have boolean third parameter. If this parameters is true it means that command and parameters is written correctly and you can use it as a sample.

release

Scripts for generating binary releases.

sdk

SDK from chip manufactor. Included in this repo to make sure that we are using the same version of this SDK to avoid any surprises from changing APIs
