// gw.sleep(SLEEP_TIME); //Seems to break recieing message, loosing ~75%

me just dumb here, delay(SLEEP_TIME); works. gw.sleep puts radio in sleep I guess.

gw.sleep() puts both Arduino and radio to sleep.

The send-methods could e.g. return the Id counter of the message sent, and an app waiting for an ack on that message should check for this value in any ack received (using some timeout)

That mean you might have to rememeber the original message. The idea is to have all the information necessary in the callback.
In my example sketches (e.g. RelayActuator) the ack message actually changes the relay status when the ack comes back from gateway. If not full message came in you would have to keep buffers with sent messages and start matching counter-values. Much more complicated.

But a message counter will probably be necessary if/when we start encrypting messages to prohibit replay attacks.

@Damme
I actually thought about having a bit in the message header which says if the message is an ack or not. With that implemented you would just call a msg.isAck() to determine if the incoming message is an ack message. Would that be ok?

You shouldn't need to call gw.process() after each send. It is only necessary in the loop() section if you expect incoming messages or have enabled repeater mode.

I don't understand what you mean with messages getting overwritten with DEBUG enabled. Could you explain it a bit more (with an example?).

To pick up the discussions about existence or not of getTemp().
A better solution would probably be to create a MySensorsATMega328-subclass of the library which contains AtMega specific stuff such as sleep() and potentially getTemp().
This class should also implement the EEPROM specifics.

You have to remember it anyway when you regard the message as lost after some time without an ack and you decide to send the message again. Only for a simple sensor node which sends a sensor value with ack, waits for an ack reply and then continues with the next sensor value this wouldn't be necessary. When a single node has multiple messages with ack 'in flight', you definately need message buffering.
This is independent from the ack message format IMHO.

I also think message buffering and retrying, when implemented, should be part of the MySensors library.
This improves realiability even more than with the NRF24 ack's enabled and avoids putting the retry-burden on the clients of the library.

here is a serial output from one of my nodes
repeater started, id 3
send: 3-3-0-0 s=255,c=0,t=18,pt=0,l=15,st=fail:1.4b1 (18848a2)
send: 3-3-0-0 s=255,c=3,t=6,pt=1,l=1,st=fail:0
send: 3-3-0-0 s=255,c=3,t=11,pt=0,l=4,st=fail:test1 (18848a2)
send: 3-3-0-0 s=255,c=3,t=12,pt=0,l=3,st=fail:2.0t1 (18848a2)
send: 3-3-0-0 s=0,c=0,t=7,pt=0,l=15,st=fail:1.4b1 (18848a2)
send: 3-3-0-0 s=1,c=0,t=6,pt=0,l=15,st=fail:1.4b1 (18848a2)
send: 3-3-0-0 s=2,c=0,t=3,pt=0,l=15,st=fail:1.4b1 (18848a2)
send: 3-3-255-255 s=255,c=3,t=7,pt=0,l=0,st=fail:1.4b1 (18848a2)

and the sketch has: gw.sendSketchInfo("test", "2.0");

yes, I know they all failed, I'm using the microwave oven atm, it kills the channel 76 (usually uses 21 but forgot to change last time, works better for me here..)

Ahh.. The strings-payloads don't seem to be terminated correctly.

I wouldn't restrict to the Atmega328. Quite some AVR's have this or simular behaviour and it would be nice to have a single library usable for all (e.g. using #ifdef's if absolutely necessary).
Seems like you're trying to move towards board- and cpu-support packages, like Linux does...

Another way to tackle it is to create a separate library to read the AVR's internal 'sensors' like the temperature sensor and e.g. the VCC voltage (as I did in https://github.com/Yveaux/arduino_vcc) and another one for persistent storage (EEPROM), and one for power management (sleep). This approach seems to follow the Arduino-way of creating a library for every 'function'.

It all depends on whether you think big and target different hardware (MPU) platforms or if you want to stick with the Arduino (or even only the ATmega328). When porting MySensors to the RPi it would be very nice if the MySensors library and examples would directly compile on both platforms.
This requires libraries to have a clear interface which doesn't limit portability to one platform or architecture.

Hello

I was looking in the nrf24l01 datasheet and found "Setup of Automatic Retransmission"
Is this something that mysensors use?

[Yveaux]

@Damme at least in the 1.4beta release. I think it's disabled in 1.3

[hek]

Yep, as @Yveaux says we use it it 1.4.

Hi guys,

I just got relays working with but struggling requesting a variable value on Beta 1.4.

My set variable commands looks as follow.

Switching On - > 1;1;1;0;2;1 (work as expected)
Off -> 1;1;1;0;2;0 (work as expected)

Request variable for the same relay -> 1;1;2;0;2; (sets the relay to 0 ???)

Can someone confirm if my request variable command is correct and if not what should it be?

Thanks

[Damme]

@lodewyk I use this:
void incomingMessage(const MyMessage &msg) {
// We only expect one type of message from controller. But we better check anyway.
if (msg.type==V_LIGHT) {
if (strlen(msg.getString())==0) {
gw.send(message.setSensor(msg.sensor).setType(V_LIGHT).set(digitalRead(msg.sensor-1+RELAY_1)?RELAY_ON:RELAY_OFF));
} else {
digitalWrite(msg.sensor-1+RELAY_1, msg.getBool()?RELAY_ON:RELAY_OFF);
gw.saveState(msg.sensor, msg.getBool());
}
}
}

(How do i use [code] ?? I start to hate this forum :P)

@lodewyk

The relay example does not support requesting state. You must add some code in incomingMessage() to handle incoming request-messages (and reply to them).

To reply incoming request-command in incomingMessage for the RelayActuator-example do something like this (note I have not compiled/tested this)

if (mGetCommand(msg) == C_REQ) {
     mSetCommand(msg, C_SET);
     msg.setDestination(msg.getSender());
     msg.set(gw.loadState(msg.getSensor());
     gw.send(msg); 
} else (
    // Do the normal stuff here
}

@DAMME and @HEK

Thanks , very helpful.

I got so occupied with the commands and never thought about the sensor code.

Thanks

This forum uses markdown. If you need help, press the little questionmark-icon in the compose window. http://daringfireball.net/projects/markdown/syntax

To decorate your codeblock use 4 spaces or one tab character first on each line.

[Yveaux]

@lodewyk hey man, you've got -2 posts.... How's that possible?

[hek]

Pushed a few new changes/bugfixes. Sorry for the slow progress. Had to wait until we got home and had the chance to do some verification.

• Ack bit in header indicating if message is an ack (see RelayWithButton for an example how to read it out).
• Sleep functions now takes unsigned long. This allows sensor to sleep for than 30 sec ;)
• Corrected string termination
