[example] GPS Sensor

[mrc-core]

hi. trying to use the code but i'm getting problems with this line "MyMessage msg(CHILD_ID_GPS, V_POSITION);"

sketch_nov15a:68: error: 'V_POSITION' was not declared in this scope
sketch_nov15a.ino: In function 'void present()':
sketch_nov15a:93: error: 'sendSketchInfo' was not declared in this scope
sketch_nov15a:96: error: 'S_GPS' was not declared in this scope
sketch_nov15a.ino: In function 'void loop()':
sketch_nov15a:125: error: 'send' was not declared in this scope
'V_POSITION' was not declared in this scope

Not getting this to work at all

@mrc-core

V_POSITION and S_GPS is only defined in the development branch.

https://github.com/mysensors/Arduino/blob/development/libraries/MySensors/core/MyMessage.h#L85

Yes, V_POSITION is not present, not even in the MySensors development branch. Do you have some unpushed code @hek ?

Thanks. I was pulling my own development branch instead of MySensor's :flushed: No wonder nothing had happened in a few days...

[mrc-core]

had to insert in the code "MySensor gw;" and some "gw." at sendSketchInfo and present to stop the errors, flash the code to arduino nano but no info at monitor serie or at domoticz gateway can't seem to find the gps...

No understanding the new problem...

[hek]

The new S_GPS/V_POSITION is only 7 days old.

I doubt @GizMoCuz has had time to implement support for it in Domoticz.

You should use the development branch like I mentioned above to make it compile out of the box.

development branch

Thanks for the quick replay. Gona try the development branch. Once again thnaks

1. Attach it to your robot lawn mower to get a notification when it has stuck somewhere.

2. Build a gps tracked pet collar (preferably using the HW RF69 module for long range operation). Used for geo fencing the dog to get a notification when it runs away. Or why not use it while hunting?

I'm in. For the mower.
For the radio, the lower frequency the better. But, we need a new gateway no ?
Or there is a trick, like a repeater node with two radio of different frequency ?

Hey @Pierre-P

Yeah, you would need a new gateway for each radio type.

Hi Guys,

new in this forum. really interresting project :-)

trid to follow your recommendations, but still have S_GPS error... do you have any developpment since the last message ?

i added the declared ligne in the MyMessage.h file, V_POSITION, but saw the S_GPS vairiable in the file.

what will need more ?

regards,

Franck

Use this version

ode only runs on the development branch. Codebender does not host this branch yet so you'll have to build it locally on your computer in the IDE:

Thanks Hek for your fast answer. now i can compile it, but i have a radio init failed...

any idea ?

I found a new mysensors page ! here:

Advanced initialization

It's also possible to construct an instance with RFM69 radio driver and/or enable signing support. You can choose one of the following radio drivers:

MyTransportNRF24 transport(RF24_CE_PIN, RF24_CS_PIN, RF24_PA_LEVEL_GW);

or

MyTransportRFM69 transport(RFM69_FREQUENCY, RFM69_NETWORKID, RF69_SPI_CS, RF69_IRQ_PIN, isRFM69HW, RF69_IRQ_NUM);
