@Yveaux i try your advice to add pull up resistor in my code and it works immediately!!!!!!
THANK YOU VERY MUCH !!!!!!
i will never find the solution without your help.
@MasMat @mfalkvidd thank you too i keep in mind th flowvhart and resistors on the ethernet connector for next issues......
thank you very much for the answer, i will try your advice and i will make a return of experience.
hello, thank you very much for the quick answer.
i programmed my DHT node with the sketch that you given. below you can see the log of the node.
the MQTT gateway is switch on during the recording.
i build my sensors with arduino nano and DHT 11.
i ordered electronic boards from this web site MY RFX. i am sure of the node because when i program a serial gateway with the same MEGA + NRF2401 i can see datas on serial monitor.
the shield w5100 is ok because i used the same to send MQTT datas to the my brokers and i can see datas on the right topic.
the only thing not very clean is i used 5cm wires to connect NRF2401 on arduino MEGA, maybe i will try to reduce the length of these wires.
one more time thank you very much for your help.

}```hello everbody, i am a new with my sensors devices and i try to use MQTT gateway with Rpi broker (mosquitto)
i try to program MQTT gateway with
i alreday modify the power supply of the NRF2401 with adding 10µF parallel 100nF capacitors between GND and +3.3V
after thta i can ping the gateway with cmd window and i see on the log ( see below) that MQTT connection is OK so i conclude that the ethernet part is OK.
i took arduino's code on my sensors web site:

*******************************
*
* REVISION HISTORY
* Version 1.0 - Henrik Ekblad
*
* DESCRIPTION
* The W5100 MQTT gateway sends radio network (or locally attached sensors) data to your MQTT broker.
* The node also listens to MY_MQTT_TOPIC_PREFIX and sends out those messages to the radio network
*
* LED purposes:
* - To use the feature, uncomment WITH_LEDS_BLINKING in MyConfig.h
* - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
* - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
* - ERR (red) - fast blink on error during transmission error or receive crc error
*
* See http://www.mysensors.org/build/esp8266_gateway for wiring instructions.
* nRF24L01+ ESP8266
* VCC VCC
* CE GPIO4
* CSN/CS GPIO15
* SCK GPIO14
* MISO GPIO12
* MOSI GPIO13
*
* Not all ESP8266 modules have all pins available on their external interface.
* This code has been tested on an ESP-12 module.
* The ESP8266 requires a certain pin configuration to download code, and another one to run code:
* - Connect REST (reset) via 10K pullup resistor to VCC, and via switch to GND ('reset switch')
* - Connect GPIO15 via 10K pulldown resistor to GND
* - Connect CH_PD via 10K resistor to VCC
* - Connect GPIO2 via 10K resistor to VCC
* - Connect GPIO0 via 10K resistor to VCC, and via switch to GND ('bootload switch')
*
* Inclusion mode button:
* - Connect GPIO5 via switch to GND ('inclusion switch')
*
* Hardware SHA204 signing is currently not supported!
*
* Make sure to fill in your ssid and WiFi password below for ssid & pass.

the compilation and programmation of arduino mega is correct but when i looked the serial port to see the debug i have many lines of informations and i do not see information from my temperature and humidity sensor
I do not see where is the problem
