I have reconnected it again and it did just starte to work as it should from the start. I changed nothing. Strange...

I still have it. I need to check how this is (not)working in single sensor environment. I will laso try not to set IT manually. Only if I get some tim to do it...

Anyone? RTFM is also accepted answer :)

Hi,

Why am I getting these:

Started!

0;0;3;0;9;send: 0-0-21-21 s=13,c=1,t=23,pt=0,l=0,st=fail:    

It can read from sensors:

0;0;3;0;9;read: 21-21-0 s=12,c=1,t=38,pt=4,l=4:4979
MyMQTT/21/12/V_VOLTAGE
0;0;3;0;9;read: 21-21-0 s=12,c=1,t=38,pt=4,l=4:5001

I switched radios but the result's the same. I also experience some problems with sending commands by hand: http://forum.mysensors.org/topic/921/strange-value-being-sent-from-controller-using-mixed-temp-relay-node/33

Do you have any clue what could be wrong?

Hi! I'm starting to play with relay and I experiencing somethings similar. I have 3 sensors (two of them works great, just temperature, volt, light and humidity) one is relay sensor. First of all it just doesn't react to my commands:

mosquitto_pub -p 1883 -h 10.0.0.11 -t MyMQTT/22/1/V_LIGHT -m "1"

serial shows just this:

connecting at 115200
repeater started, id 22
send: 22-22-0-0 s=255,c=0,t=18,pt=0,l=3,st=ok:1.4
send: 22-22-0-0 s=255,c=3,t=6,pt=1,l=1,st=fail:0
send: 22-22-0-0 s=255,c=3,t=11,pt=0,l=12,st=ok:Relay sketch
send: 22-22-0-0 s=255,c=3,t=12,pt=0,l=3,st=ok:1.0
send: 22-22-0-0 s=1,c=0,t=3,pt=0,l=3,st=ok:1.4

I'm using stock http://www.mysensors.org/build/relay code, just setting node_id manually to 22.

On the controller I have:

0;0;3;0;9;read: 21-21-0 s=11,c=1,t=0,pt=7,l=5:23.0
publish: MyMQTT/21/11/V_TEMP 23.0
0;0;3;0;9;send: 0-0-21-21 s=11,c=1,t=0,pt=0,l=7,st=fail:23.0001
0;0;3;0;9;send: 0-0-22-22 s=1,c=1,t=2,pt=0,l=7,st=fail:13.0001

It looks like it tries to send '1' with garbage from last sensor read.

It does this with my humidity sensor:

publish: MyMQTT/21/12/V_VOLTAGE 5001
0;0;3;0;9;send: 0-0-21-21 s=12,c=1,t=38,pt=0,l=4,st=ok:5001
0;0;3;0;9;read: 21-21-0 s=10,c=1,t=1,pt=7,l=5:52.0

0;0;3;0;9;send: 0-0-21-21 s=10,c=1,t=1,pt=0,l=8,st=fail:52.05001

I am also using MQTT client gateway which @gadu recommended me.

I did not understood how does this workaround @Gambituk mention work. Do you know what is going on above? What am I doing wrong?

P.S. Using standart EthernetGateway code also scrambles messages (please note strange sing after '1'):

0;0;3;0;9;send: 0-0-22-22 s=1,c=1,t=2,pt=0,l=2,st=fail:1à

after this relay node does not accept any message (you can see st=fail on the last line - that was me retrying mosquitto_pub -p 1883 -h 10.0.0.34 -t MyMQTT/22/1/V_LIGHT -m "1").

OK, I've probably fixed it :)

It was bad connection on Dallas sensor so sensor node did not send any data and that was why I did not receive any :)

But what is this garbage on the serial?

Hi!

I'm having hard time setting up MQTT ethernet gateway. My gateway is set up on 10.0.35:

^^^ some more garbage.

I'm using:

Arduino Uno (GW)
Ethernet Shield on W5100

Arduino Pro mini 3,3V

NRF24L01 Radios. SoftSPI enabled.

So the problem is that I do not get anything with mosquittp_sub. What is wrong?

PS. I did not connect decoupling capacitor. Gateway and sensor are laying 5cm besides each other.

I also managed to get it working! Besides non '+' radio I did not have SoftSPI enabled. I thought that I do not need it since I have a Ethernet Shield version. After enabling MQTT Gateway and MQTT ClientGateway started.

Now it's time for some soldering to make a client :)

@gadu - thank you very much!

In the meanwhile I managed to compile on @ntruchsess code. I got past compiler error and also I noticed that my baund rater for serial monitor was incorrect (so I couldn't see anything usefull). Anyway I got this:

0;0;3;0;9;check wires

On all controllers: MQTTGateway, Ethernet gateway, Serial... I checked those wires many times, even I switched the radio. No luck. Then I noticed that I bought NRF24L01 - the verison withot + at the and. It should be NRF24L01+

Does it matter? I found that NRF24L01+ it differs only slightly from NRF24L01 version but I think that might be the casue. Anyone had such experience? It's hard to search for it on the forum since everyone is writing about NRF24L01+ only...

Last night I downloaded whole https://github.com/ntruchsess/MySensors/tree/mqttclient branch and tried to compile it - I got errors that ntruchsess supposed to fix in this branch (https://github.com/knolleary/pubsubclient/pull/47). Which is weird, I suspect some problems with my IDE... I will look into this today.

I can't compile this... After applying the patch I got some new error. @gadu Could you possibly share source files and version of your Arduino IDE?

Thanks for the answer but it's not the point - mosquitto_sub doesn't even connect to the server (Connection timed out).

How can I send you more data? I tried to println to serial:

int main(void) {
	init();
	Ethernet.begin(TCP_MAC, TCP_IP);
    Serial.println("Ether initialized");
	delay(1000);   // Wait for Ethernet to get configured.
	gw.begin(RF24_PA_LEVEL_GW, RF24_CHANNEL, RF24_DATARATE, writeEthernet, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN);
	Serial.println("GW started");

but it does not print anything besides some machine characters (ÿûï). If I add Serial.begin(9600); just after init I got "Ether initialized" but no GW started message.

Putting Serial.println in MyMQTT.cp after first line in this procedure doesn't print anything:

void MyMQTT::begin(rf24_pa_dbm_e paLevel, uint8_t channel, rf24_datarate_e dataRate, void (*inDataCallback)
		(const char *, uint8_t *), uint8_t _rx, uint8_t _tx, uint8_t _er) {
	Serial.begin(BAUD_RATE);
	Serial.println("Beginning GW begin");
	repeaterMode = true;
	isGateway = true;
	MQTTClientConnected = false;

I got:

Hi!

I am having problems with setting MQTTEthernet Controller (using stock MQTTGateway.ino). I have Arduino Uno with Ethernet shield (I've also attached radion but I'm not using it now). I changed MAC, IP addresss and uploaded to the board. It starts and I am able to ping it:

pi@raspberrypi ~ $ ping 10.0.0.150
PING 10.0.0.150 (10.0.0.150) 56(84) bytes of data.

2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 0.508/0.511/0.515/0.022 ms

but clients are having trouble communicating:

pi@raspberrypi ~ $ mosquitto_sub -h 10.0.0.150 -t '#'
Error: Connection timed out
pi@raspberrypi ~ $ mosquitto_pub -h 10.0.0.150 -p 1883 -m "test" -t "/MyMQTT/20/1"
Error: Connection timed out

Scanning on port 1883 reveals nothing (port closed).

What could be the cause? How can I debug this?

P.S. Debugging on serial shows that is stopps on
gw.begin(RF24_PA_LEVEL_GW, RF24_CHANNEL, RF24_DATARATE, writeEthernet, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN);

commenting this line and also additionaly
gw.processRadioMessage();

doesn't make it respond to mqtt clients...
