I am trying to send an SS command to the network. I get a "sending a request" message, but the SS command (in this case a divert) does not activate. I can only suppose it is something to do with the way I am preparing it, as the SS command is valid. Code below:

#include <config.h>
#include <turbo/turbo.h>

u8 PROGMEM t_Foo_en[] = "DIVERTED";
u8 PROGMEM t_Text_ss[]="*21*phonenumberhere#";

void deflect (void *data)
{
u8 *buf = buf_A ();
u8 len = 0;
u8 i;
u8 *response;
buf[len++] = T_SS_STRING | CR_FLAG;
buf[len++] = strlen(t_Text_ss);
for (i = 0; i < strlen(t_Text_ss); i++)
buf[len++] = rb(t_Text_ss+i);
stk_cmd (STK_CMD_SEND_SS, 0x00, DEV_ID_NETWORK, len);
display_text_raw (t_Text_ss, Q_DISPLAY_TEXT_HIGH_PRIORITY);
}


void turbo_handler (u8 action, void *data)
{
switch (action)
{
case ACTION_APP_INIT:
case ACTION_INSERT_MENU:
insert_menu (t_Foo_en);
break;
case ACTION_MENU_SELECTION:
stk_thread (deflect, data);
break;
default:
break;
}
}

OK, so I read a bit more, and see I'm not converting the string to 7 bit

I tried something very simple: I set up unconditional voice divert, and then tried to cancel it with

u8 PROGMEM t_Text_ss[]={0x23,0x59,0x6C,0x04};

in my previous code - I now get a brief "Wait" message, and then nothing

I'm really stuck - Is there anyone out there? I don't feel I'm getting true value from my purchase!

Thanks

I don't have the 11.14 specs but check the SS string notation, maybe it's like a msisdn - swapped nibbles, not ascii.

[pz]

So it has to be coded as msisdn, e.g.
u8 PROGMEM t_ss_no_21[] = { 0xff, 0xbb, 0x12, 0xfb}; // ##21#

[johnsecret]

It worked perfectly! Many thanks

now on to AT commands

[johnsecret]

I am screaming quietly here - Do you have a function that will do the ascii to MSISDN format conversion?

thanks

GOT IT!

For the benefit of anyone else who needs it.

The string is a) BCD packed, and b) made up of decimal semi-octets

Confused?

BCD is a way of representing decimal numbers. The key here is that "*" is 'a' and "#" is 'b'

So the number ##21# is bb21b

But, you have to make up your decimal semi octals.

If you have an odd number of characters, you add an "f" at the end

Hence:

bb21bf

Then you swap the pairs:

bb12fb

And for good measure, you seem to stick "ff" on the front end, which gives you the string earlier in the thread.

Hope that helps someone else
