Jeedom on RaspberryPI with Arduino Uno on USB and remote Arduino pro mini

[technoant]

Dear All,
i'm doing a project with Jeedom and Mysensors.

Raspberry PI 2 B [Jeedom] ---(usb)---> Arduino Uno [Serial Gateway] ---(nrf24)--> 433Mhz <---(nrf24)--- Arduino pro mini Sparkfun ---> dht11

I use Mysensors Framework v2.1.1 for both Arduinos.

I hope to manage several Arduino pro mini through Jeedom.

I used tutorial Jeedom

* DESCRIPTION
* The ArduinoGateway prints data received from sensors on the serial link.
* The gateway accepts input on seral which will be sent out on radio network.
*
* The GW code is designed for Arduino Nano 328p / 16MHz
*
* Wire connections (OPTIONAL):
* - Inclusion button should be connected between digital pin 3 and GND
* - RX/TX/ERR leds need to be connected between +5V (anode) and digital pin 6/5/4 with resistor 270-330R in a series
*
* LEDs (OPTIONAL):
* - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs
* - RX (green) - blink fast on radio message recieved. In inclusion mode will blink fast only on presentation recieved
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or recieve crc error

Hi,

could you give us more info about your arduino pro mini node (how it is powered etc)? or a pic?
Looks like you may have a bad radio wiring..
Also, have you added a capacitor for nrf?
https://www.mysensors.org/build/connect_radio
This should work out of the box.

[technoant]

@scalz My Arduino pro mino is currently powered through USB-TTL with 3.3v as it is a 3.3v arduino pro mini.

I though it was a wiring issue but i re-wired it several time looking at the tutorial to connect radio and i had no chance to work.

I didn't put yet capacitor.

[technoant]

@scalz I have added capacitor on both nrf24 the one on the Arduino Uno [SerialGateway] and the one on Arduino pro mini.

I still have the same messages on the Arduino pro mini..

[technoant]

I removed the DHT11 from the Arduino pro mini and it seems to work.

I guess it is due to parallal plug on VCC for DHT11 and NRF24.

I successed to include the arduino micro in Mysensors plugin of Jeedom.

Now everything work.

I plugged the DHT11 vcc on FTDI Header vcc pin.

I plugged the USB ttl vcc on raw pin.

And now everything work fine.
