Hello, Here is my problem: I declared a new AT command AT+NTPSERV : adl\_atCmdSubscribe ( “AT+NTPSERV”, Cmd\_NTPSERV\_Handler, ADL\_CMD\_TYPE\_READ | ADL\_CMD\_TYPE\_PARA | 0x0011 ); When using AT+SERV from the UART1 port of the Q24plus (over the eval board), it works fine. However when using: adl\_atCmdCreate( “AT+NTPSERV?\r”, FALSE, ManageNewMessage\_Resp\_Handler, “\*”, NULL ); I received the ERROR message, while adl\_atCmdCreate( “AT+CSQ\r”, FALSE, ManageNewMessage\_Resp\_Handler, “\*”, NULL ); works fine. for info: bool ManageNewMessage\_Resp\_Handler(adl\_atResponse\_t \*paras) { adl\_atSendResponse ( ADL\_AT\_UNS, paras-\>StrData ); return TRUE; }//endprog Any idea? thank you for your help.

adl\_atCmdCreate only works with the standard, built-in AT commands; You cannot use adl\_atCmdCreate to issue your own custom commands. What would be the point? Just have your application call the appropriate function(s) direct! 8) ---

Thank you awneil for your help. My application handles a proprietary serial protocol. Serail frames start by “EA” (0x45 0x41) adn end by . For this reason I switch the UART1 in data mode, but I would like to be able to send my custom AT commands while in data mode. Thank you for your help. Laurent ---

If you really want to do this, you should write your own wrapper to handle your custom AT commands. ---

I do have problem as well with atCmdCreate where i need to specify array pointer that will contain the value after the equal sign of the at comand. This array sould be added the the cpbp at command. If i use the name of the array as followes: adl\_atCmdCreate(“at+cpbp=“num””, FALSE, Handler, “\*”, NULL); With the above format I get search for the ascii vallue of -num- and not the value that is in the array pointer itself. Adding the name of the array as follows after the comand itself will return an error. adl\_atCmdCreate(“at+cpbp”+num, FALSE, Handler, “\*”, NULL); Is there anyone knows how to add pointer to array in this adl ? ---

I wouldn’t try to print the resulting string to the console though…the control chars may bollox things up. ciao, Dave ---

You don’t actually want the backslash characters in the string - you just want the double quotes. The backslash is just there to “escape” the double quotes when you enter them as part of a string! ---

it will take me days to find out that actually no one ever tried this before , but i am doubt about it… can you please give an example how to put the at command ,concatenated with pointer to a buffer to the adl\_CmdCreat? ---

Again, this has nothing to do with Wavecom, OPen-AT or ADL. It’s basic, standard, textbook ANSI ‘C’ - use of sprintf. Try doing it in a “normal” C compiler until you can get printf to display the string you want… ---

Just sending the sprintf without relating it to the adl\_atCmdCreat will not give me anything. i did not understand what will sprintf contribute? In order to use the at comand i need to specify the comand format in ascii to - ascii \*atstr , is that correct? as i said before adding the correct number to the at comand that i need to send is trivial , it is the format of the string itself and the why it appers inside the array returns the error after jumping into this adl on the debuugging stage. I have tried to use b as the array that represents \*atstr with the following options: b[]="at+cpbp=“0123456"” returns error b[]="at+cpbp=“0123456"” returns error as well ---

> [@rami](#): > > Just sending the sprintf without relating it to the adl\_atCmdCreat will not give me anything. > i did not understand what will sprintf contribute? Use sprintf to build the string that you require. If you don’t know how to do that in a “normal” C program outside of Open-AT and ADL, then you obviously won’t be able to do it with the added complications of Open-AT and ADL! So get it going in a plain, vanilla “ordinary” C application first. > [@](#): > > In order to use the at comand i need to specify the comand format in ascii to - ascii \*atstr , is that correct?

Again, this is standard ‘C’ stuff - nothing specifically to do with Wavecom, Open-AT, or ADL. ---

> [@rami](#): > > returns error You need to state clearly what, exactly, returns an eror - and what error, exactly, it returns! eg: - An error in your ‘C’ syntax will cause the compiler to give an error; - An error in the way that you call adl\_atCmdCreate may cause that function to return an error result code; - An error in the AT command itself will cause an ERROR response. ---

Here is an example of using sprintf to build a string and subsequently using that string: ```auto #include int main( int argc, char* argv[] ) { // Strings to be formed into the message char hello_string[] = "Hello"; char world_string[] = "world"; // Buffer into which to build the message char string_to_print[80]; // Build the message sprintf( string_to_print, "%s, %s!\n", hello_string, world_string ); // Print it! printf( string_to_print ); // all done. return 0; } ``` You should be able to build that using any standard ‘C’ compiler to run it on a standard host system (not Open-AT). Then experiment with adapting it to form the AT Command that you require… Once you have that working, then move it into your Open-AT application… ---

The error is in the at command itself and it is +CME ERROR: 22 which means number is not existed. I see it after a breakpoint that i put on the comand handler ```auto bool Handler(adl_atResponse_t *paras) { rs = (ascii *)adl_memGet(paras->StrLength); \\ Breakpoint is here wm_strRemoveCRLF(rs, paras->StrData, paras->StrLength); wm_strcpy(buf,rs); \\buf = +CME ERROR: 22 } ``` > [@](#): > > b="at+cpbp=“0123456"” > returns error > > b=“at+cpbp="0123456"” > returns error as well this is only an explenation of whats insid the srings that i send with the adl . ---
