I am trying to get server text response that sent after i make the dial
am getting the log like this
From: ;tag=as121b5ca6
To: "me" ;tag=FP0KRz3fkxBtR6q19Er1ykMXhHCqtqOU

i want to fetch the 'ResultHead'
knowing that i get many like these messages ..is there any function (am sure there is but i cant see it ) to fetch this messages only or at least the header as string ..
i think i need to use this function but i dunno how!!
static pjsip_rx_data *get_rx_data(pjsip_event *e)
{
if (e->type == PJSIP_EVENT_RX_MSG)
return e->body.rx_msg.rdata;
if (e->type == PJSIP_EVENT_TSX_STATE && e->body.tsx_state.type == PJSIP_EVENT_RX_MSG)
return e->body.tsx_state.src.rdata;
// There's no rdata on this eevnt
return NULL;
}
*I use siphon on top of Pjsip ..thnx
i hope my question is clear
looks i ended up answering my question
since its hard to find the answer at least it was for me .. I'll post it in hope that somebody will make use of it ..
first you need to create new module and register it ,
fisrt create the pjsip_module
pj_bool_t logging_on_rx_msg(pjsip_rx_data *rdata);
static pj_status_t logging_on_tx_msg(pjsip_tx_data *tdata);
static pjsip_module my_pjsua_msg_logger =
{
NULL, NULL, /* prev, next. */
{ "my_mod-pjsua-log", 13 }, /* Name. */
-1, /* Id */
PJSIP_MOD_PRIORITY_TRANSPORT_LAYER-1,/* Priority */
NULL, /* load() */
NULL, /* start() */
NULL, /* stop() */
NULL, /* unload() */
&logging_on_rx_msg, /* on_rx_request() */
&logging_on_rx_msg, /* on_rx_response() */
&logging_on_tx_msg, /* on_tx_request. */
&logging_on_tx_msg, /* on_tx_response() */
NULL, /* on_tsx_state() */
};
in the sip_connect function use
pjsip_endpt_register_module(pjsua_get_pjsip_endpt(), &my_pjsua_msg_logger);
and now the implementation of the reciepient functions
static pj_status_t logging_on_tx_msg(pjsip_tx_data *tdata)
{
/* Important note:
* tp_info field is only valid after outgoing messages has passed
* transport layer. So don't try to access tp_info when the module
* has lower priority than transport layer.
*/
/* Always return success, otherwise message will not get sent! */
return PJ_SUCCESS;
}
pj_bool_t logging_on_rx_msg(pjsip_rx_data *rdata)
{
NSLog(#"\n recieving rx msg %s--end my joy",rdata->msg_info.msg_buf);
if (rdata->msg_info.msg->type == PJSIP_RESPONSE_MSG)
{
do something
}
return PJ_FALSE;

I'm trying to read a MODBUS sensor via an ESP32.
I'm using the following library: https://github.com/emelianov/modbus-esp8266
I have the following code:
#include <ModbusRTU.h>
#include <SoftwareSerial.h>
SoftwareSerial modBusSerial;
ModbusRTU modbus;
#define startReg 100
#define endReg 123
uint16_t res[endReg - startReg + 1];
// Callback to monitor errors in the modbus
bool cb(Modbus::ResultCode event, uint16_t transactionId, void* data) {
if (event != Modbus::EX_SUCCESS) {
Serial.print("Request result: 0x");
Serial.print(event, HEX);
}
return true;
}
void setup() {
Serial.begin(115200); // Default serial port (Hardware serial)
modBusSerial.begin(9600, SWSERIAL_8E1, MB_RX, MB_TX); // modbus configuration SWSERIAL_8E1 = 8 bits data, even parity and 1 stop-bit
modbus.begin(&modBusSerial);
modbus.master();
Serial.println("starting modbus...");
while (true) {
Serial.println(modBusSerial.read());
res[endReg - startReg] = 0; // string terminator to allow to use res as char*
if (!modbus.slave()) {
modbus.readIreg(16, startReg, res, endReg - startReg, cb);
}
modbus.task();
Serial.print("result: ");
Serial.println((char*) res);
delay(1000); // every second
}
}
Response I get;
When I do the exact same in QModMaster, I do get the correct output. Anyone any idea what I'm doing wrong here?
These are the settings I use;
I am aware of the "wrong" address in my code. I have 2 identical sensors but one is connected to my computer while the other one is connected to my ESP32.
Thanks in advance!
I would like my esp8266 to retrieve the mac address of the AP it`s connected to as a client (station), following this discussion on How to get Access Point MAC adress.
Here is my code:
#include <ESP8266WiFi.h>
const char* ssid = "somrmthing";
const char* password = "somrmthing"; //
const char* host = "aubs.gear.host"; //create webserver & correct address
uint8_t MAC_array[6];
char MAC_char[18];
void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
delay(100);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
int value = 0;
void loop() {
// put your main code here, to run repeatedly:
/*
* http://stackoverflow.com/questions/34078497/esp8266-wificlient-simple-http-get
*/
delay(30000);
++value;
/*

*/
Serial.print("connecting to ");
Serial.println(host);
// Use WiFiClient class to create TCP connections
WiFiClient client;
const int httpPort = 80;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}

For void wifi_handle_event_cb(System_Event_t *evt) I get the following error:
C:\Users\Tinotenda\Desktop\ver1.0\ver1.0.ino: In function 'void setup()':
ver1.0:48: error: a function-definition is not allowed here before '{' token
void loop() {
^
ver1.0:129: error: expected '}' at end of input
}
^
exit status 1
a function-definition is not allowed here before '{' token
How can I fix that?
Your setup()-function doesn't have it's closing bracket.
You should also place all the global variables at the top, or make them static inside the function that uses them. (ref: int value = 0 ,although I don't know what you're using the variable for)
Furthermore, avoid the user of very long delays. delay(30000)causes the ESP8266 IP-stack to behave strangely. You should better use the millis-structure:
static unsigned long lastMillis = 0;
if (millis() - lastMillis < 30 * 1000UL) {
lastMillis = millis();
//do your stuff
}
This answer should help other beginners:
Copy and pasting code without understanding the basics is never a good idea.
Basic structure of an Arduino program (=sketch)
Definitions, global vars
int value = 0;
should be placed there
SETUP
void setup(){
All one time functions, initalization routines, etc
}
LOOP
void loop(){
recuring tasks call functions from here in the above example
Call the example function like this
wifi_handle_event_cb(SomeParamToHandOver);
NEVER use delay - it stops processing for the given time
Not a good idea in server client scenarios ->
look for blink without delay in the Arduino examples for more
Never use while in here it may lead to dead locks
}
functions/modules you call from the setup or loop
void wifi_handle_event_cb(System_Event_t *evt) {
Exmple from the question
}
plus all remarks in the answer above

I wanted to write a client server thing using gio socket in gtk and I found a sample code to send data to server but, the more thing i want is to read the data/reply sent by the server. The below is sample code
#include <glib.h>
#include <gio/gio.h>
int main (int argc, char *argv[])
{
/* initialize glib */
g_type_init ();
GError * error = NULL;
/* create a new connection */
GSocketConnection * connection = NULL;
GSocketClient * client = g_socket_client_new();
/* connect to the host */
connection = g_socket_client_connect_to_host (client,
(gchar*)"localhost",
1500, /* your port goes here */
NULL,
&error);
/* don't forget to check for errors */
if (error != NULL)
{
g_error (error->message);
}
else
{
g_print ("Connection successful!\n");
}
/* use the connection */
GInputStream * istream = g_io_stream_get_input_stream (G_IO_STREAM (connection));
GOutputStream * ostream = g_io_stream_get_output_stream (G_IO_STREAM (connection));
g_output_stream_write (ostream,
"Hello server!", /* your message goes here */
13, /* length of your message */
NULL,
&error);
/* don't forget to check for errors */
if (error != NULL)
{
g_error (error->message);
}
return 0;
}
The above code works fine for the sending data to server but when i try to read it form input stream it goes in to block state. My read message function look like this
void readMessage()
{
char buffer[2048];
GInputStream * istream = g_io_stream_get_input_stream (G_IO_STREAM(connection));
gssize bytes;
bytes = g_input_stream_read(istream, buffer, sizeof buffer, NULL, NULL);
buffer[bytes] = '\0';
g_print ("%"G_GSSIZE_FORMAT" bytes read: %s\n", bytes, buffer);
}
g_input_stream_read() is documented as blocking until it receives as many bytes as you request (in this case, 2048), or until the connection is closed. Presumably, neither of those things are happening. How big is the reply from the server? Does it close the connection after sending its reply?
Bear in mind that g_socket_client_connect_to_host() opens a TCP connection, so you should expect to be doing stream-based I/O here, rather than message-based I/O. If you expect to be sending messages to and from the server, you will need a framing protocol within TCP.
I want to implement a GIO socket client server program where the server can serve up to say 5 clients at the same time. Is this even possible? How can I modify the following standard server to allow multiple clients to connect in a thread safe way? The incoming_callback() function will receive data from a client and do some processing and respond an acknowledgement and this will continue till the client sends an "exit" message at which point the server will close the client connection. I want to do this for a max of say 5 connections at a time for the server. Is it possible and if so how?
int
main (int argc, char **argv)
{
/* initialize glib */
g_type_init();
GError * error = NULL;
/* create the new socketservice */
GSocketService * service = g_socket_service_new ();
/* connect to the port */
g_socket_listener_add_inet_port ((GSocketListener*)service,
1500, /* your port goes here */
NULL,
&error);
/* don't forget to check for errors */
if (error != NULL)
{
g_error (error->message);
}
/* listen to the 'incoming' signal */
g_signal_connect (service,
"incoming",
G_CALLBACK (incoming_callback),
NULL);
/* start the socket service */
g_socket_service_start (service);
/* enter mainloop */
g_print ("Waiting for client!\n");
GMainLoop *loop = g_main_loop_new(NULL, FALSE);
g_main_loop_run(loop);
return 0;
}
The magic should happen within your incoming_callback, returning as fast as possible and pushing the work into another GThread (or even better, a GThreadPool)
Can you please tell me if there is any example for using GIO Server Socket
(the one which I can open a port and listen on socket requests)?
I would like to use it to 'remote-control' my GTK+ application.
I think you should do something like this:
#define MY_PORT 47110
/* Listener callback, this gets called by GTK+ when
* there's socket activity to handle.
*/
static gboolean cb_listener(GIOChannel *source, GIOCondition condition, gpointer data
{
switch(condition)
{
case G_IO_IN:
/* There's data to be read. */
break;
default:
/* An error has occured, or socket is closed. */
return FALSE; /* This tells GIO to remove the source, might be drastic. */
}
return TRUE; /* This tells GIO that all is fine. */
}
Then elsewhere (in a function, maybe main()):
GSocketListener *listener;
listener = g_socket_listener_new();
g_socket_listener_add_inet_port(listener, MY_PORT, NULL, NULL);
g_io_add_watch(G_IO_CHANNEL(listener), G_IO_IN | G_IO_ERR | G_IO_HUP, cb_listener, NULL);
