CLI over UART Unresponsive

[Dave_couling]

I developed a FreeRTOS application which uses NRF_LOG and CLI enabled.  The CLI is used to accept user input, and I used NRF_LOG for system logging.  Everything works great over RTT, however the UART only prints out the welcome message then basically freezes.  Occasionally after running for a minute it will seem to response to user input, but usually by that point the user input history has just buffered up.  I enabled logging on the CLI UART and see a ton of activity.  To the point where logs are dropped.  Its curious how this is happening, when there is no issues on RTT.

The parameter I enable for UART logging is NRF_CLI_UART_CONFIG_LOG_ENABLED 

Anyone seen this issue on SDK 15.2?

Hi Dave,

It looks like I'm facing a similar problem to yours. I had filed this issue: https://devzone.nordicsemi.com/f/nordic-q-a/48934/logging-over-cli-with-freertos but did not get any responses from the community.

Were you able to find a way to get CLI working with FreeRTOS?

Thanks,

Wael

Nope, what I ended up doing was using the FreeRTOS+ source code which contains its own CLI module.  I brought that source code into my project and connected it to the SDK peripherals.  Its a very similar API to the SDK CLI
