There's something wrong with PHONEBOOK

There's something wrong with PHONEBOOK.
When I try to change memory phonebook, for example, to ME,
lwcell_pb_list(LWCELL_MEM_ME, 1, pb_entries, LWCELL_ARRAYSIZE(pb_entries), &pb_entries_read, NULL, NULL, 1);
the command to change memory phonebook does not work.

When I set a debugging breakpoint at:
} else if (CMD_IS_CUR(LWCELL_CMD_CPBS_SET) && !strncmp(rcv->data, "+CPBS", 5)) {
lwcelli_parse_cpbs(rcv->data, 2); /* Parse +CPBS response */
}
but there the program never stops on lwcelli_parse_cpbs(...).

Can you tell me the return value of the lwcell_pb_list?

[edbek]

lwcell_pb_entry_t pb_entries[10];
size_t pb_entries_read;

    lwcell_pb_enable(NULL, NULL, 1);
    lwcell_pb_read(LWCELL_MEM_ME, 1, pb_entries, NULL, NULL, 1);
    lwcell_pb_list(LWCELL_MEM_ME, 1, pb_entries, LWCELL_ARRAYSIZE(pb_entries), &pb_entries_read, NULL, NULL, 1);

After executing this block of code, it turns out that pb_entries[0] and all the rest pb_entries[...] are equal:

mem = LWCELL_MEM_SM_P
pos = 0
name = ""
number = ""
type = 0

And return value of all 3 function calls?

[edbek]

yes, after each of the 3 calls the data does not change and will remain so:

mem = LWCELL_MEM_SM_P
pos = 0
name = ""
number = ""
type = 0

but I see that there is only one response from the modem during these 3 calls:
+CPBS: ("SM", "ME", "ON", "FD")

and I don’t see the АТ-command being called to install memory phonebook. The code never goes here:

case LWCELL_CMD_CPBS_SET: { /* Get current memory info */
             lwcell_mem_t mem;
             AT_PORT_SEND_BEGIN_AT();
             AT_PORT_SEND_CONST_STR("+CPBS=");

[MaJerle]

Can you give me return values of these 3 functions please?

[edbek]

all functions return lwcellOK

lwcellr_t ret;
       
      ret = lwcell_pb_enable(NULL, NULL, 1);

  //here ret = lwcellOK

  ret = lwcell_pb_read(LWCELL_MEM_ME, 1, pb_entries, NULL, NULL, 1);
  //here ret = lwcellOK

  ret = lwcell_pb_list(LWCELL_MEM_ME, 1, pb_entries, LWCELL_ARRAYSIZE(pb_entries), &pb_entries_read, NULL, NULL, 1);
  //and here ret = lwcellOK

[MaJerle]

Can you enable full lib log and provide full at commands exchange between mcu and modem?

[edbek]

Yes, I can, but it won't be soon. I just started working with the GSM modem and I don’t know what will happen.
I would like to get advice from you now.

Thank you.

[MaJerle]

I am not able to give good advice at this point. I do not know the model you have nor I know if your driver properly works to enter all data.

It is strange that all functions return OK, too.
