Best practise for at_client apps? Shell APIs or CONSOLE_SUBSYS to run at commands?

[zafersn]

Hi,

Currently, I am working on an at_client application which allows me to run at commands over an uart bridge (st mcu)
my question is when I use the shell apis, I have to add my custom command prefix with at commands. Is it possible to send directly at commands and process them with shell APIs? without any prefix, i.e.: at+cfun? or would the console getline/getchar be better for this?

for example: if I use shell Api:

static int shell_hl_send_at_cmd(const struct shell *shell, size_t argc, char **argv)
{
	int rc = 0;

	if ((argc == 2) && (argv[0] != NULL) && (argv[1] != NULL)) {
		rc = mdm_hl7812_send_at_cmd_netf(argv[1]);
		if (rc < 0) {
			shell_error(shell, "Command not accepted");
		}
	} else {
		shell_error(shell, "Wrong number of parameters");

		rc = -EINVAL;
	}

	return rc;
}
SHELL_STATIC_SUBCMD_SET_CREATE(
	hl_cmds, 
	SHELL_CMD_ARG(cmd, NULL,
		      "Send AT command"
		      "net cmd <at command>",
		      shell_hl_send_at_cmd, 2, 0),
	SHELL_SUBCMD_SET_END /* Array terminated. */
);
SHELL_CMD_REGISTER(net, &hl_cmds, "HL7812 commands", NULL);

to send an at command to the modem I have to send at commands with net cmd prefix.

net cmd at+cfun?
but I dont want to add net cmd and want to send only at+cfun? over serial terminal.
