Message deserialization issues during node initialization

[nicolas]

Hello there!

First of all, thanks for this project... I'm still in my first steps but that looks pretty cool: simple, feature full, efficient and tightly bound to MySensors (looks better than most of other gateway I could have tested till now).

I face a problem just after having successfully configured my MySensors serial gateway, when I try to make my first node join: I see two rows whereas I expect only one (only one node is up).

The node is a simple S_BINARY node, that runs over RFM69HW (moteino, same for gateway).

In addition, mycontroller logs several errors:

It looks like I receive weird payloads:

or even

Do you have any idea?

The DummyNode sketch is actually pretty simple and uses MySensors@2.2.0:

#define MY_RADIO_RFM69
#define MY_IS_RFM69HW
#define MY_RFM69_FREQUENCY (RFM69_868MHZ)

#define MY_DEBUG

#include <MySensors.h>

#define ID_LED_COMMAND 1
#define LED_PIN 9

void setLed(bool status) {
	digitalWrite(LED_PIN, status ? HIGH : LOW);
}

void before() {
	pinMode(LED_PIN, OUTPUT);
	setLed(true);
}

void setup() {
}


void presentation() {
	sendSketchInfo("DummyNode", "1.0");
	present(ID_LED_COMMAND, S_BINARY, "Set onboard LED on/off");
}

void loop() {
	wait(5000, C_SET, V_STATUS);
}

void receive(const MyMessage &msg) {
	switch (msg.type) {
	case V_STATUS:
		setLed(msg.getBool());
		break;
	}
}

But probably due to the problem above, I see my sensor, but I can't do anything with it (I don't see any call to action to switch the state of my S_BINARY)

For instance, I'd to know where I can find the button described here in the wiki.

Nicolas

@nicolas Thank you for your interest with MyController.

when I try to make my first node join: I see two rows whereas I expect only one (only one node is up).

Gateway will act as a Node too. Gateway id is 0. So it is showing two nodes, one is the gateway and another one your node.

It looks like I receive weird payloads:
Unknown message format:[^@]
or even
java.lang.NumberFormatException: For input string: "^@^@0"

Do you have any idea?

can you post your gateway configuration page? Looks like your gateway sends some weird payloads.

But probably due to the problem above, I see my sensor, but I can't do anything with it (I don't see any call to action to switch the state of my S_BINARY)

You can add the switch in two ways,

• Add it to UI directly. (add a Status variable)
• Add request payload from your node code( request(ID_LED_COMMAND, V_STATUS);)

UI (edit sensor on ui):

Node code:

void presentation() {
	sendSketchInfo("DummyNode", "1.0");
	present(ID_LED_COMMAND, S_BINARY, "Set onboard LED on/off");
        request(ID_LED_COMMAND, V_STATUS);
}

Hi @jkandasa and thanks a lot for your answer!

Here is my gateway sketch:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_RFM69
#define MY_IS_RFM69HW
#define MY_RFM69_FREQUENCY (RFM69_868MHZ)

// Enable serial gateway
#define MY_GATEWAY_SERIAL

#include <MySensors.h>

void setup()
{
        // Setup locally attached sensors
}

void presentation()
{
        // Present locally attached sensors
}

void loop()
{
        // Send locally attached sensor data here
}

I enabled MY_DEBUG but it may be a mistake and the cause of the problem. I'll try without!

I got it for the button part, everything looks ok for my dummy node, thanks!
