CLI losing incoming data

[Alexander]

I have used the cli module in SDK 15.0.0 to create a test interface for a API I have built over UART. It works problem free when typing commands by hand but when automating the testing using Python pyserial library I seem to lose data when issuing commands. I have seen this forum post https://devzone.nordicsemi.com/f/nordic-q-a/29289/cli-overrun-by-remote-host and it is very similar to what I am seeing. It is however quiet old and I would like to know if updates to SDK that is talked about have been applied in 15.0.0? If not, how would I go about to apply them?

Hi,

With next SDK release we will add LibUARTE as a CLI backend, this shall fix your problem.

Until that time you can use a fix we proposed some time ago:

I see libUARTE is included as experimental library in SDK 15.1.0. Could you provide the steps needed to use libUARTE as backed for cli? And maybe explain what the difference is between UARTE and regular UART driver and backend?

SDK 15.1 is currently not available. If you have already downloaded it please check an example:

sdk\nrf5\examples\peripheral\experimental_cli_libuarte

Hi, I seem to be having a very similar issue, were you able to resolve this?

Not sure which SDK you are using but the cli_libuarte example in 15.1 and above is working great.
