First steps with jeedom and mqtt


i’ve installed jeedom in a debian virtual machine for test, and add the mqtt plugins, don’t forget to configure the user name and the password and configure the correct network interface

then create a mqtt receiver called « essaialarme » and an info called « test_bis »

from a PC inside the network of the jeedom workstation , type

mosquitto_pub -h 192.168.xyz.zyx -u "login" -P "password" -t essaialarme/pix -m 50

or using python and mosquitto module :

import mosquitto
 
def on_message(mosq, obj, msg):
	print "%-20s %d %s" % (msg.topic, msg.qos, msg.payload)
	mosq.publish('pong', "Thanks", 0)
 
def on_publish(mosq, obj, mid):
	print "published"
	pass
 
cli = mosquitto.Mosquitto()
cli.on_message = on_message
cli.on_publish = on_publish
cli.username_pw_set("login", password="password")
cli.connect("192.168.xyz.zyx", 1883, 60)
cli.subscribe("essaialarme/test_bis", 0)
cli.publish ("essaialarme/test_bis","12345")

 

 

olimex A20 lime2 debian jessie image with 3.4.103 kernel, 2D & H264 acceleration


the current image available here https://www.olimex.com/wiki/A20-OLinuXino-LIME2
is a wheezy version limited to 4gb
– first, i copy the content of this image into a 16gb sdcard and resize the second partition
– boot the A20 LIME 2 card and copy the current kernel (3.4.90) configuration available in /proc/config.gz
– i cross compile the linux sunxi kernel (3.4.103) using the config and activate CONFIG_FHANDLE, because udev will request it during upgrade, for i use a linux mint 17 distro & this tuto https://olimex.wordpress.com/2013/11/05/building-the-ultimate-debian-sd-card-for-linux-with-kernel-3-4-for-a20-olinuxino-micro/
– install the new kernel & module into the sdcard
– edit the /etc/network/interface , to configure eth0 in dhcp and reboot
– edit the the source.list and replace each wheezy occurence by jessie
– apt-get update&&apt-get upgrade&&apt-get dist-upgrade (take many cup of coffee )
– install Xorg acceleration , using the https://linux-sunxi.org/Xorg
– install cedrus acceleration , https://linux-sunxi.org/Cedrus
– reboot
– test with mplayer / mpv & ffmpeg
have fun !

esp8266 flashing with nodemcu firmware (linux debian testing)


flashing the ESP-01 using node MCU

i use this thread http://www.esp8266.com/viewtopic.php?f=23&t=1062#p5963

kadamski « lead the way »

download esp open sdk

first clone the esp open sdk and compile it standalone (take a while), without root because i have access to this
cd /opt/Espressif/nodemcu
git clone https://github.com/pfalcon/esp-open-sdk.git
cd /opt/Espressif/nodemcu/esp-open-sdk
make STANDALONE=y
take a coffee 🙂 after that modify your path env variable
export PATH=/opt/Espressif/nodemcu/esp-open-sdk/xtensa-lx106-elf/bin:$PATH
after that download nodemcu
cd /opt/Espressif/nodemcu/nodemcu-firmware
git clone https://github.com/nodemcu/nodemcu-firmware.git

compile nodemcu

compile  nodemcu using the compiler
cd /opt/Espressif/nodemcu/nodemcu-firmware
make

upload nodemcu to the ESP-01

prepare the firmware and download it
cd /opt/Espressif/nodemcu/nodemcu-firmware
esptool.py elf2image app/.output/eagle/debug/image/eagle.app.v6.out
esptool.py write_flash 0x00000 app/.output/eagle/debug/image/eagle.app.v6.out-0x00000.bin 0x10000 app/.output/eagle/debug/image/eagle.app.v6.out-0x10000.bin
connect minicom to the card (9600baud 8N1) and then reboot the ESP , if its ok you will see that prompt
>NodeMCU 0.9.5 build 20150213 powered by Lua 5.1.4
lua: cannot open init.lua
>

upload init.lua file

works very well
