Help sending payload with more decimal places

[therik]

Hey guys,

Just wondering if someone would be so kind as to help me figure out how to use setters to send a payload with more decimal places than the standard custom variable.

I saw that perhaps I could construct the msg "on the fly", but I don't know the proper syntax to get that accomplished. Even easier, I would simply like to send a custom variable with two decimal places (or however many one should like). Right now the default is a single decimal place as I gather from the data that is being sent currently.

In the plainest terms, I would like to send the battery voltage in a format X.XX using a custom variable, but using the standard custom variable constructor the payload is X.X.

Thanks for your help.

multiply your float with 100 or 1000 before sending and divide again on the receiving end.

the second argument to the MyMessage.set-method is the number of decimals.

@hek okay, I guess I was being stupid....

With this msg constructor...

MyMessage msgVolt(CHILD_ID_VOLT, V_VAR1);

With this type def...

 float batteryV  = sensorValue * 0.003363075;

I had the following thinking that I had turned on auto ack...

  gw.send(msgVolt.set(batteryV, 1));

but that sets the decimal places to "1". So, if I want to set the decimal places to "2" and enable auto ack it would look like this...?

  gw.send(msgVolt.set(batteryV, 2),1);

Thanks again.

Yes, this is correct.
