  • Hi thank you for helping me, it was useful :) Now it is possible to send data with decimal. I was trying to receive data like this: loat lon=((float *)packet.data)[0]; float lat=((float *)packet.data)[1]; Serial.println(((float *)packet.data)[0],4); Serial.println(((float *)packet.data)[1],4); But without success. What could the problem be? Again I want to than you :) Commented Oct 29, 2014 at 10:36
  • The output I got is 0.0000 and 0.0000 Commented Oct 29, 2014 at 11:18
  • Did you update the packet size (data.length)? Each float eats 4 bytes, so it has to be 8 now. Commented Oct 30, 2014 at 6:35
  • Hi, I'm not able to fix it by my self. How/where can I update the the packet size? Commented Oct 30, 2014 at 11:00
  • Try data.length=8 in your send_data routine. Commented Oct 30, 2014 at 14:05
