Porting MySensors to work with the RadioHead library

[hek]

Ah.. doh..

Moved parts of the low-power library into MyHwATMega328 and forgot the ISR-thingie.

https://github.com/mysensors/Arduino/blob/master/libraries/MySensors/utility/LowPower.cpp#L850

Good catch.

[kolaf]

Glad I could help :-). I guess my prize will be that you patch this so that I do not have to create a pull request ;)

[kolaf]

I might as well continue while I'm at it :-)

Another weird issue I'm having is that every node requests a new ID whenever it starts, but it does not switch to the new ID it receives. It just continues with the old ID it already had.

When I wipe the ROM it requests a new ID as expected, and this time it is saved and used for subsequent communication. Why is it requesting a new ID when it boots, when it already has one?

[hek]

@kolaf

Should not happen. Will look at it later tonight.

[hek]

Ok, finally got the thumbs out and actually tested the RFM69 code using a couple of Moteinos. They seem to communicate just fine. :)

Tested with SerialGateway<->RelayActuator-Example.

I can also report success and things look pretty good. Had to change the line:

//MyTransportRFM69 transport;
MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, true, RF69_IRQ_NUM);

So that the rfm69HW could be supported.

Now, on to see if I can get the MQTT working.

[kolaf]

@reddy11 I had to do the same, although I did the change in the default parameters for the function definition since all my radios are HW :-).

I'm not using the MQTT gateway, I'm using the serial gateway together with a Perl script someone here made which functions as a MQTT gateway, and which I modified to handle node ID assignments.

[kolaf]

@hek You didn't see any extra node ID requests when the sensor booted?

[tekka]

@kolaf are you using the OTA bootloader?

[kolaf]

@tekka said:

@kolaf are you using the OTA bootloader?

No, I haven't figured out that part yet. I'm not even sure if I have available flash memory for this, nor if this is expected to work with the rf69 radios.

[tekka]

@kolaf ok, i was asking because there is an issue wIth the ID assignment and the OTA bl in the dev branch resulting in the scenario you described.

Thanks everybody for the nice work! My initial tests also work out of the box with a serial gateway and humidity node. I will let it run over the weekend to see if there are any issues coming up.

I have serial gateway running on a MoteinoMega and a node running on a Moteino with RFM69HW radios... Using the 2April2015 build of the development arm... with the addition of the :

//MyTransportRFM69 transport;
MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, true, RF69_IRQ_NUM);

and the correct pin-out for the radios and LED for these boards...

I needed to mod the MsTimer2.cpp file to add 'AVR_ATmega1284P ' to each of the #ifdef line to support the Mega

As I do not yet have a controller running, I see the gateway output as below when the node TX's:

0;0;3;0;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0,sg=0:255;255;3;0;3;

[lafleur]

I need a simple controller that can plot data that can be viewed on a web server... Mac/Pi or ??
want hr/day/week/mo/yr plots..

what do you recommend??

[reddy11]

@kolaf I gave up on getting the MQTT gateway working. I just dont think there is enough memory in my moteino to use the rf69 and the uipethernet library. I was able to get it to work, but it would crash after a few min. When I updated to the latest UIPEthernet library for the 1.5 series, It was too large to upload. So....anyway...can you elaborate on, or point me to the serial-mqtt script you were referring to?
Thanks!

[kolaf]

@reddy11 Sure, you can find it here: https://github.com/Yveaux/MySensors_MQTTGateway

You will want to use version 2 of the script.

It does simple note ID assignments by keeping a list of all ids it has seen and choosing the first ID not in this list when receiving an ID request.

There are some dependencies, but you will notice that as you start the script :-)

Hi,

i've tried to scroll back many of the pages of this thread, to find out how to use the Radiohead version of mysensors but with no success, considering that i don"t understand many of those things said here ... :-(

Is there someone that can help me a little and give me a minimalist modop ? i've used Radiohead on its own with 3 moteinos but mooving to MySensors seem to be the best way to integrate them in a standard domotix architecture ... i currently use Jeedom for a year now.

Of course, you'll have my feedbacks ...

Use the development branch (https://github.com/mysensors/Arduino/tree/development/libraries/MySensors)
and enable MyTransportRFM69 transport layer in gateway and sensor.

Uncomment this line for gateway (and use the same setup for sensor):
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/examples/SerialGateway/SerialGateway.ino#L63

[nikorun]

Hello Hek,

Thanks for your answer, I will try this as soon as I'll be back home.

When you say* "uncomment this line ..."* , do I have to comment the previous one (MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);) ?
Furthermore, as described in your exemple, the line to be uncommented has no argument but in a previous post reddy11 has to add several ones:
MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, true, RF69_IRQ_NUM);

Is it only due to the "H" version of the module ?

Again, thanks for your time. I really think Radiohead is a impressive library as well as MySensor si very smart , the both should be terrible !!!

Nicolas

[hek]

Yes, disable or remove the MyTransportNRF24 transport line.

If you write

MyTransportRFM69 transport;

It will use default constructor arguments defined here:
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/MyTransportRFM69.h#L33
and here:
https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/MyConfig.h#L129-L133
