CLI command with parameter

[Pawel]

Hello,

I would like to have something like this:

ROOT_COMMAND SubCommand CustomParameter

Example:

DeviceName Set ExampleDeviceName

Where CustomParameter can be a string or hex value, that I would like to get and store in non volatile memory using Flash Data Storage. Is it possible with CLI? What is the right approach?

Hi,

Yes it is possible and quite easy with CLI.

I would recommend to implement handlers for both commands: DeviceName and Set. DeviceName can have a simple handler to print command help - please refer to CLI examples. Actual handler shall be implemented within Set command. To make it even more easy I would recommend you to implement 2 subcommands: SetString and SetHex.

I would do it like that:

NRF_CLI_CREATE_STATIC_SUBCMD_SET(m_sub_device_name)
{
    NRF_CLI_CMD(SetHex,    NULL, "Your subcommand help string.",  cmd_set_hex),
    NRF_CLI_CMD(SetString, NULL, "Your subcommand help string.",  cmd_set_string),
    NRF_CLI_SUBCMD_SET_END
};
NRF_CLI_CMD_REGISTER(DeviceName,
                     &m_sub_device_name,
                     "Your command help string.",
                     cmd_device_name);
