hello, I’m with a similar problem on the code.
I`m using the same agent code from tempbug to opena channel and send the data to xively.
What I’m trying to do:
1)Arduino sends data trough softserial (2400) to imp in this format: (ok)
2)Imp gets the data string and splits the string into the individual sensor data (I’m only extracting temp data to make things simpler, after I got temp working I will implement the others: light, soil humidity and air humidity.) Imp reports through serve.log the temp data so it gets a (Ok).
3)Imp sends this temp data to agent (not ok Agent server.log is not shown on log)
4)Agent creates channel and post data to xively (not ok)
Help is much appreciated. how can I fix the float error shown by the log?
This is what I get from the server log:
2014-01-24 16:19:54 UTC-2: [Status] Device booting; 2.81% program storage used 2014-01-24 16:20:49 UTC-2: [Device] Temp:24.60 2014-01-24 16:20:49 UTC-2: [Device] ERROR: float expected for the specified format 2014-01-24 16:20:49 UTC-2: [Device] ERROR: at checkUART:30 2014-01-24 16:20:54 UTC-2: [Status] Device disconnected; 42 bytes sent, 0 received, 42 total
