Gateway just another sensor node?

[gohan]

I think the code is missing the send command for the voltage. Also include a little longer serial output. Did you check with myscontroller if actually no values are sent?

Use wait(), never delay().

i'm trying to send the R0 value which is calculated from voltage

for(int x = 0 ; x < 100 ; x++)
{
  sensorValue = sensorValue + analogRead(A0);
}
sensorValue = sensorValue/100.0;
/*-----------------------------------------------*/

sensor_volt = sensorValue/1024*5.0;
RS_air = (5.0-sensor_volt)/sensor_volt; // omit *RL
R0 = RS_air/9.9; // The ratio of RS/R0 is 9.9 in LPG gas

OK, but you need to post complete code that gives problem and longer serial output

@hek
i've changed delay to wait, but the behaviour is still the same. Seems like "my" serial output in the loop is overwritten by the "debug" serial output.
It is somehow related to the send command and usage of gateway as a sensor, but i don't get whats wrong :confused:

@gohan
the code was complete in the first post (now its only "wait" instead of "delay" in the end).

Here is a longer serial output for active "send command":

sensor_volt = 0.05V

You cannot print your own debug messages on a serial gateway as it is the mean of communication against the gateway. The controller will try to interpret your prints according to the serial protocol.

Please check if you are not having resets in your gateway due to this:

@Michiel-van-der-Wulp and @hek
Guys, thank you for fast help. Both answers helped me to solve the problem!

@hek I found that out while testing my very first/current gateway. Also, it is no good idea to define MY_DISABLED_SERIAL. (sssst, don't tell anyone i did that).
..but still, it's assuring to have my findings confirmed by an expert.
