Please, need help getting RPi controller working with MQTT



  • I'm just starting out with MySensors and home automation in general. Been trying to get Home Assistant working with this gateway and an irrigation node. Had the gateway and node working fine using RPi ethernet build but could not get Home Assistant to recognize any nodes. After much trial and tribulation I decided to try out MQTT on the RPi (through GPIO, sans Arduino) using the config:

    ./configure --my-rf24-irq-pin=15 --my-leds-err-pin=12 --my-leds-rx-pin=16 --my-leds-tx-pin=18 --my-leds-blinking-inverse --my-rf24-channel=69 --my-rf24-pa-level=RF24_PA_LOW --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1
    

    I "sudo make" it and run "sudo ./bin/mysgw -d" and get the following output:

    mysgw: Starting gateway...
    mysgw: Protocol version - 2.2.0-beta
    mysgw: MCO:BGN:INIT GW,CP=RNNG--Q-,VER=2.2.0-beta

    mysgw: MQTT connected
    mysgw: Sending message on topic: mysensors-out/0/255/0/0/18
    mysgw: TSF:SAN:OK
    

    Perfect. "sudo make install", enable service and start it. I move over to the sensor with the arduino and load the attached (though much pared down) sketch.

    I'll omit the remainder of the code, as I don't THINK it's important for this issue (correct me if I'm wrong) and I don't want to make you guys waste your time crawling through a lot of unnecessaries. Here is the output that I get from the serial monitor. The gateway/controller is running about 2 ft away from the node.

    And on and on and on. Any ideas why I can't get this to connect to the parent? I had no problem with this part using the basic ethernet (non-mqtt) build. Thanks for looking! Yay first post.



  • Forgot to mention:
    I'm using an Arduino Nano.
    I'm using the development branch for MySensors Arduino library
    1.8.3 Arduino IDE
    The nrf module on the Pi is regulated using one of these:
    http://www.ebay.com/itm/5Pcs-DC-DC-4-5V-7V-to-3-3V-AMS1117-3-3V-Power-Supply-Module-Volt-Regulator-N24/401258780242?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
    modulated to 3.3V. These come equipped with SMD capacitors, so didn't think there would be a need for an electrolytic one as well.
    The nrf on the Arduino gets power from the 3v3 out and has a 104 ceramic cap on the power and ground.

    Can't think of any other important details for now..

    These come equipped with SMD capacitors, so didn't think there would be a need for an electrolytic one as well.

    @Ethan-Kalebaugh - NO REPLY indicates the radios can not find eachother or find the route to eachother. I would never skip the 4.7uF capacitor on the nrf module even though I have a 0.1 and 10uF cap helping the voltage regulator.



  • Alright I've soldered a 4.7uf cap across each nrf power and ground, but I am still getting the exact same behavior. Any more suggestions?
