Opening client connection to remote server shows success even if no server is started on the specified remote IP and port #80

The AT command P6=1 always gives success even if there is no server with the specified IP address and port. Is there a way to check if the target as client actually got connected to the specified server ?

@iampoonam - I think this question should rather be asked to Inventek support .

Facing the same issue too, my current workaround is to inherit class InternetSocket and use ISM43362_socket to inspect the protected member nsapi_socket_t _socket to check whether is connected to remote socket. Like this:

#include "TCPSocket.h"

// Copy from ISM43362Interface.cpp. Reference: https://github.com/ARMmbed/wifi-ism43362/blob/3813a4bb8623cc9b0525978748581f60d47142fa/ISM43362Interface.cpp#L301-L308
struct ISM43362_socket {
  int id;
  nsapi_protocol_t proto;
  volatile bool connected;
  // SocketAddress addr;
  // char read_data[1400];
  // volatile uint32_t read_data_size;
};

class TCPClient : protected TCPSocket {
  bool connected() { return ((struct ISM43362_socket*)_socket)->connected; }
}

Hi If you have some good workaround that can be shared with all, don't hesitate to propose a pull request :-) Thx
