Command Line Interface Data Validation nRF5 SDK

[Darius]

I'm using the CLI interface through USB and UART, and I am wondering if there are any innate methods for checking the validity of the data being sent and received via the CLI. For example, is there a method to append a checksum to each CLI output, and require one to be sent in to process a command? Or would this all be custom user implementation?

Hi

There is no innate method for data validation in the CLI library in the nRF5 SDK AFAIK, but I will ask some of the old trotters internally if they're aware of something. I'll let you know if I hear back, but I wouldn't hold my breath waiting for an update unfortunately.

One thing could be to use the parity bit on the UART for validating the data, as something like CRC/checksums is not something we have in the nRF5 SDK.

Best regards,

Simon
