Thread network technology - 04 Programming Thread network over API and sending a UDP-package

Thread is a network technology for wireless networks based on IPv6. It is ideally suited for home automation, Industry 4.0 and wireless sensor-actuator networks. In this video, we program a thread network via an API with the Nordic nRF5 SDK for Thread. For the programming we are using two developer board nRF52840-dk. We setting our own network parameter over the API and sending an UDP-package from one device to another.

Sooperub...Really wonderful and Knowledgeable...Thankyou very much....Please do more videos....

I had trouble with the udp_receive board crashing when I powered on the udp_send board. Making the "mySocket" variable in the udp_init() function static appears to resolve the issue for me (i.e., change line 113 in your example code from "otUdpSocket mySocket;" to "static otUdpSocket mySocket;"). Any idea why this might be the case for me?

Here we are sending message via realm mesh Multicast address...how we send messge to a particular device? How we find MLEID of that devicem while sendig UDP mesaage

[mimoghosh]

could you pls tell me how could i connect automatically into previously paired network after disconnected from it?

Great Video, thanks a lot, i have problems with the udp initialization this seems not to be working i need to open the udp and bind it manualy, i wanted to download the source code but it requieres logins.
