I'm writing a simple application for Netduino which sends some data in CSV format to Xively. When sending multiple entry in CSV I must include a timestamp for each value. The message I send is this:
Sensor no. 1,0,2014-05-01T23:20:40Z
Sensor no. 2,0,2014-05-01T23:20:40Z
Sensor no. 3,0,2014-05-01T23:20:40Z
I receive always a status code 400, with this message:"CSV Parser Error: Invalid timestamp". The timestamp is in ISO 8601 format. Where am i making a mistake?
