October 2012 – Caru's stuff

Dinstar SMS API client

I just committed the project that uses libdwgsms to send/receive text messages through Dinstar’s branded gateways.

The code goes as simple as follows, and you can check it from my github account:

/* * main.c * * Created on: Sep 19, 2012 * Author: caruizdiaz * caruizdiaz.com */ #include "dwg/dwg_util.h" #include "dwg/dwg.h" #define LISTEN_PORT 7008 #define SEND_SMS_PORT 0 void new_sms_handler(str_t *gw_ip, dwg_sms_received_t *sms) { LOG(L_DEBUG, "[%.*s] Encoding: %d, From: %s, Len: %d, Text: %.*s\n", gw_ip->len, gw_ip->s, sms->encoding, sms->number, sms->message.len, sms->message.len, sms->message.s); } void status_handler(str_t *gw_ip, dwg_ports_status_t *status) { int index = 0; LOG(L_DEBUG, "\t[%.*s] Number of ports: %d\n", gw_ip->len, gw_ip->s, status->size); for (index = 0; index < status->size; index++) { LOG(L_DEBUG, "\tPort%d: %d\n", index, status->status_array[index].status); } } void msg_response_handler(str_t *gw_ip, dwg_sms_response_t *response) { LOG(L_DEBUG, "\t[%.*s] ACK response from %s\n", gw_ip->len, gw_ip->s, response->number); } int main(int argc, char** argv) { dwg_message_callback_t callbacks = { .status_callback = status_handler, .msg_response_callback = msg_response_handler, .msg_sms_recv_callback = new_sms_handler }; LOG(L_DEBUG, "%s: Setting up sever... \n", __FUNCTION__); dwg_start_server(LISTEN_PORT, &callbacks); LOG(L_DEBUG, "%s: Server listening at port %d\n", __FUNCTION__, LISTEN_PORT); str_t des = { "59598146623", sizeof("59598146623") - 1}; str_t msg = { "test from PY!", sizeof("test from PY!") - 1 }; for(;;) { getchar(); dwg_send_sms(&des, &msg, SEND_SMS_PORT); } return 0; }

Dinstar SMS API update

I’ve been working very hard in the past few months that updating my blog was relegated to the least of my priorities. It’s a pity, but I had no choice :(.

Back on the track, I came here to present an update of the Dinstar’s SMS API implementation which I started writing some time ago. I paused the project several times mostly because I had no economic reason to support my time on it , but luckily, the situation changed and today the great majority of the API is implemented and working.

I don’t maintain a changelog other than the one on github commit list, but basically, this is what changed:

– Support for API 1.4 and 2.0
– Support for authentication mechanism. (This is partial, check source code)
– Support for RSSI packages
– Support for Unicode strings
– The project is no longer a standalone application, now is a shared library.
– Several bug fixes

The C# bindings are also ready. I will publish the code probably next week.
