That happens when you have already reached the maximum connection count, and start scanning again.

This makes sense: there is no point in starting scanning when you are already at the maximum connection count; ie, you will not be able to make any more connections.

Think about it - you have 2 options:

Increase your maximum connection count (it's in the sdk_config);
Don't try to connect when you are already at the maximum connection count

Hello Nordic Team,

I would like to add to the above question by Hitesh that the error code 18 means that the "Maximum connection count exceeded". Also this error is occurring when the peripheral device is not yet connected. Please help to resolve this issue as soon as possible.

Thanks & Regards,

Aswati
