CC2650: How to send data from PC to CC2650 Launchpad over UART

Do you use teraterm to enter “ON” or “OFF” and then press "CTRL+Enter" to send ON or OFF command?

Yes I did but I did not see anything happen. Sometimes the serial printing also not happen properly.

I will try with that examples. Thanks for the reply

Do you use XDS simulated Application COM port for testing this?

What is XDS simulated Application COM port ? Im sorry I am a bit new to the CC2650 and Contiki. What I did was just copied the example code, made the bin file, uploaded it to the board via flash programmer and tested by connecting to the com port using Teraterm.

Yeah I used that one. But still I could not make it done with the cc2650 launchpad. We do not need to do any modification to the code right? Just need to do is that making the bin file using that code and upload it to the board and send ON using the console. I dont know why it is not working

I just do the test on my LAUNCHXL-CC2650 and it works fine. I attach my binary for your reference.

I uploaded your bin file and opened the user application com port through Teraterm. And when I tried to type "ON" (with and without " " ) the characters that I typed did not appear in the console screen. And to enter the command, I used Ctrl+Enter as you mentioned but nothing happened. Any idea? I really need to done this thing because I need to send some data from an ATmega MCU.

The characters that you typed won't appear in the console screen, you only need to make sure you key in "ON" without "" and then press Ctrl+Enter to turn on LED.

Still it did not work. :( Sir this is the board that I am using. Could you please check whether is there any jumper mis-attachment? 

Nothing. Just the cursor.

You should see something output on teraterm. Can you open two teraterm connecting to two different COM ports emulated by LAUNCHXL-CC2650 and see if there’s anything output? Remember to press reset button on LAUNCHXL-CC2650 after you open and connect teraterm.

Yes, you still need to feed it.

Thanks for the information Sir. Well when I captured the tun6 interface packets and checked, for some inputs (for both int and string inputs) the received packet has a protocol saying SKYPE. Do you have any idea about that incident? How can the protocol would be changed according to the received data?

I couldn’t understand your latest descriptions and question. Can you elaborate?

Well when I manually inputed some data ("Hi" , numbers such as 1346,2567,15) over UART to the TI board which was configured as the udp-client. Then I observed the received (To the TI board configured as Border Router) through the tunslip6 interface from the wireshark installed in raspberry pi. However I noticed for some packets, the protocol field has been changed as SKYPE (Not UDP). Have you encountered such a situation? As far as I know, the protocol cannot be changed according to the data that we transfer over 6LoWPAN. I hope the question is clear sir.
