Disabling VT100 Commands in SDK14

[wael]

I'm in the process of updating from SDK13 to SDK14. In the new CLI, there are a lot of NRF_CLI_VT100_CMD's that are used which weren't there before. If someone is using a plain serial port terminal application with no terminal emulation (like CoolTerm for example which is a popular option on macOS), having these VT100 commands adds a lot of garbage ASCII characters in the logging/CLI output. I couldn't find a way to disable these VT100 commands (all defined in nrf_cli_vt100.h) even though there's a way to disable VT100 colors.

• Has anybody else ran into this problem?
• It there any way to disable these VT100 commands?

Hi

In case you are using Logger module with CLI you will not avoid VT100 commands. There are needed for commands like: clear screen, saving cursor position, restoring cursor position and so on.

If you are not using CLI as Logger backend you can try integrate CLI from SDK13. I think I saw a user who did it without bigger problem.

Another alternative if you are using MAC is to try application: iTerm2

screen /dev/tty.usbmodemXXXX 115200
// where XXXX refers to devkit serial port

We were able to configure it to interpret VT100 commands correctly:

Thanks Jacub.

Integrating CLI from SDK13 is not very straight forward and would involve touching a lot of files to make them work with the old logging and CLI modules.

Supporting VT100 commands by default without a way to disable it is an unwelcome change in SDK14. If we are using the CLI and the logging modules to interface with units in setups that we have little control over like on a factory floor, this makes our life very hard.
