Multiple Netduinos within one local Network

23 November 2012 - 07:45 AM

Hello all together, i´ve received a second Netduino from a friend of mine. So i thought about setting up a small sensor network in my flat. Sensing different things for the beginning just the climate within and outside of the flat. Whatever this works fine! Both Netduinos are running (basically) the same programs. But... when i connect them both to the local Network just one of them works. My start up progress: - switching on Netduino #1 (IP: 192.168.1.100) - within the start up #1 sets it´s IP and starts working - checking connection from my Laptop (IP 192.168.1.20) ping to #1 -> works fine - switching on Netduino #2 (IP: 192.168.1.200) - same start up sequence like #1 - checking connection Laptop -> #2 -> works fine - want to call #1 doesn´t work anymore - pinging returns timeout tried solutions: - different network ports - different network IP´s - different style of connecting (switching on, then connecting networkcable, etc.) - basically the network connection if the Netduino which is connected first stops working when the second one is connected Any ideas or am I just missing something? Regards and thanks for help Runner

High Speed Ethernet

17 February 2012 - 01:40 PM

Hey all, I hope someone could help me a little bit. My Netduino has diffrent operating states like: - reading out a sensing device via I2C - reading an analog input - wait for order - reboot and set initial states - .... When i am reading out the meassured data from I2C or an analog port I build data packages to send then via UDP to a local Pc. The Netduino is just a listener in the network. It reacts to special orders which are sent by the Pc via Labview. Everything works fine I really have no problems to set up a communication or something else... BUT.... And here the Problem starts.... it is just to slow! I am watching at the network traffic with wireshark. As you can see in the picture there are some DHCP packages.. Where do they come from?? And how to shut them down? and if you calculate the frequenc of the measured data... there are just 350 values per second... how is it possible to use the full 10Mbps of the Ethernet?? The Netduino has the IP 192.168.5.100 and LabView 192.168.5.10 The Netduino is listening to the Ethernet if there are some new orders from LabView to execute. but there are no differences in the transition speed if i check for a new order after every measured value or after 1000. I hope someone could help me cause working with the Netduino is really interesting. Thanks in advance Runner
