when i compile and load the code, the socket is connecting.but my server is unable to recognise my request. shall i share you the whole cpp code?

It looks to me like handler is not dealing with the IPV6 address but I could be wring.
wrong
Ok, how have you created my_socket ? that is the bit that will use the IPV6 address and open a connection to the remote server if i am not mistaken.
once you have that then im not sure you need to pass the address in the data stream like you have...
"POST /api/v1/localservertbhw16lab/telemetry HTTP/1.1\r\nHost: 2001:db8:abcd:a:d54c:4b07:8738:9bfc\r\nContent-Type: application/json\r\nContent-Length: %d\r\n\r\n", payload_str_len);
unless there is a handler of some kind that builds the link based on this data then just passes the data over.
static void init_socket()
{
if (MBED_CONF_APP_BUTTON != NC) {
my_button.fall(&my_button_isr);
my_button.mode(MBED_CONF_APP_BUTTON_MODE);
}
{
if (MBED_CONF_APP_BUTTON != NC) {
my_button.fall(&my_button_isr);
my_button.mode(MBED_CONF_APP_BUTTON_MODE);
}
nsapi_error_t open_result = my_socket.open(network_if);
if (open_result != 0)
{
printf("Error! socket.open(net) returned: %d\n", open_result);
}
int errConnect = my_socket.connect(server, 8080); //"demo.thingsboard.io", 80
while(true)
{
if(errConnect != 0)
{
printf("Could not connect to socket : error = %d\r\n", errConnect);
wait(60);
errConnect = my_socket.connect(server, 8080);
// TODO Manage connection issues here !!!!
}
else
{
printf("Socket connected\r\n");
break;
}
this is how i created
and the server sends me back 400 error
400 = bar request so the server is rejecting something that you are sending.
what you need to do is rem out all of the bits of code that send data with the exception of the code that builds the socket. then see if it gives you a 400 error. if it does then look in the thingsboard log. open up a windows power shell, go to where thingsboard is storing its log and run Get-Content thingsboard .log -Tail 10

really? is the remote server windows based as well?
400 = bad request not bar.. lol..
generally, for remote server, we can check in any browser in our thingsboard.io account
i ran in command promt as adminstrator
without the quotes on windows 10
and the log file is normally located in C:\Program Files (x86)\thingsboard\logs
@vangalvin thank you for your help today, i will ping you again here if it doesnt work.
hello i used postman for send telemetry data to device
postman http code 200ok but i dont see telemetry data on device
how to fixed it?
@vangalvin : and i can see the log folder in the directory given C:\Program Files (x86)\thingsboard\logs
i’m able to send a specific command and turn it on but only this
What variable stores the state so i can use it in action code and send everytime the opposite value
any ideas ?
