RFM69 temperature and how to check RFM69 is set to high power

[carlierd]

Hello,

I am using RFM69HW and found how to use high power reading this post. I am now want to get the RFM69 temperature in my sketch and check if I am using high power mode.

I found in the RFM69 library useful methods, but I don't know how to call them in my sketch ... I tried radio.readTemperature but it's not correct.

Do you have an idea ?
I am also interesting in getting the RSSI !

Thanks,

David.

Guess you would have to add something like this in your sketch:

extern RFM69 _radio;

And use use _radio.readTemperature()

(in the development branch)

In 1.5 the radio-object is a private member of the MySensors radio-driver class so you'd have to make it public to have access to it.

Thanks @hek !

I modified the file "MyTransportRFM69.h" and moved RFM69 radio from private to public.

I then added extern RFM69 _radio; in my sketch.
And in the loop method, I also added _radio.readTemperature().

But the compilation failed:

SerialGateway.cpp.o: In function `loop':
/Users/carlierd/SerialGateway.ino:130: undefined reference to `_radio'
/Users/carlierd/SerialGateway.ino:130: undefined reference to `_radio'
collect2: error: ld returned 1 exit status

For the moment I prefer using the stable branch until I get something working.

You're mixing the two solutions.

In 1.5 you would reach the public radio object by

radio.radio.readTemperature()

Sorry @hek but it's still not clear for me

I am using 1.5, so I assume that I have to:

• put radio as public in MyTransportRFM69.h
• add radio.radio.readTemperature() in my sketch

Thanks !

Yep, should work.

I got this error during compilation:

SerialGateway.ino: In function 'void loop()':
SerialGateway:128: error: 'radio' was not declared in this scope
'radio' was not declared in this scope

Any idea ?

[hek]

transport.radio.getTemperature() then? O

It's perfect !! Thanks !
