CLI one byte commands

[enukic]

I'm working on an application that utilizes CLI library, and I need to add CLI commands as in the code below:

NRF_CLI_CMD_REGISTER(0x1, NULL, "PING", cmd_ping);

But when I attempt this I get an error message:

error: invalid suffix "_str_ptr" on integer constant
1> ../../../../components/libraries/experimental_section_vars/nrf_section.h:149:5: note: in definition of macro 'NRF_SECTION_ITEM_REGISTER'
1> ../../../../components/libraries/util/nordic_common.h:116:31: note: in expansion of macro 'CONCAT_2_'
1> ../../../../components/libraries/cli/nrf_cli.h:155:65: note: in expansion of macro 'CONCAT_2'

So basically, I need to have one-byte commands. My initial idea was to convert hexadecimal numbers to ASCII characters and register commands as:

 

NRF_CLI_CMD_REGISTER(**ASCII CHARACTER**, NULL, "PING", cmd_ping);

But that didn't work either. 

Thanks

Best regards

Hi,

NRF_CLI_CMD_REGISTER() macro will concatenate the p_syntax arguments into a variable name: p_syntax ## _str_ptr. Variable names starting with a number is not supported in C, see this page.

Apart from this, I do not experience any problems when testing with single char, i.e. like this:

NRF_CLI_CMD_REGISTER(p, NULL, "PING", cmd_ping);

Do you get any errors when using a single letter?

Best regards,
Jørgen

Does that work with just the single character, or does it still need 'Enter' to "action" the command ?

Hi,

I realized that after spending some time in nrf_cli.h, reading #defines.

Thank you for clarifying that for me.

I do not experience any problems when testing with single char, works fine for me.

Best regards
