Hello Sir,

Does anybody has the fiollowing experience in Thread code with KW41 ?

We used router Eligible Device code loading into FRDM-KW41 and tried to create, bind and listen to the socket using TCP and UDP. The KW41 will be reboot immediately as soon as it received Socket Bind command for the TCP protocol + Stream socket type. If I used UDP protocol + datagram socket type, socket bind didn’t Return error but then we are not able to listen to the socket – the command returned an error.

The log from Test Tools is attached for your reference.

Dear Jason Chiang,

Thread only uses UDP. TCP is no longer supported, that function is probably a remains from legacy builds which is no longer supported and should be removed.

Hi Estephania,

We just encountered some problems during UDP transfer test, with “router eligible deivce” sample code.

The first problem I encountered is that if I put the aforementioned source code( It is the compiled “router eligible device” sample code, with “Thread use THCI” option enabled in config.h header file) into the server and the client and tried to send data from the client, the server said no data available.

The second problem is that if I recompiled the source code with “Thread with Shell” option on and loaded it into the client (the firmware

in the server was kept the same as previous case - “router eligible device” with “Thread with THCI” option on) , the server could receive

something but the data it received appeared completely something else.

Your feedback is appreciated.

You can find attached Test Tool and Wireshark logs that demonstrate how to use UDP sockets on a Thread Host Controlled Device using SDK from MCUXpresso, Thread v1.1.1.15
