CLI 16 character limit?

[Keith V]

I have a small program that is to be used in production to test my device. It has to be scriptable so I'm using teraterm over rtt.

No external IO for a serial port.

Everything is working great until I try to issue a long command, anything > 16 characters

So 'mfg led all on' is OK but 'mfg led all off' fails. When I press enter the first time I just see a CR, no LF, if I press enter a second time the command works.

if I change the command to 'mfg led all of' it works again!

I've looked through nrf_cli.c but I don't see anything.

SO there looks like a limit of 15 characters?

Oh, so this only happens in teraterm and putty, it works in the Segger IDE and in rtt viewer. So I'm now thinking it's a issue with the terminal programs??

Thanks for any insight

Hi Keith,

There is not 16 character limit in the CLI. I notice that you only see issues with the UART backend and not the RTT backend, so perhaps there is something related to your UART buffer configuration? Can you share your sdk_config.h so I can see if I spot anything there? Which SDK version are you using?
