SPRacing F3 EVO guide

It is shown in the Drontrest’s - SPRacing F3 flight controller Guide (9June2018) that for… UART1 the Data MSP is clicked -and for Telemetry is chosen SmartPort - Is this correct…joe

Data MSP is a virtual uart and should always be selected.
Telemetry is sent over smart audio to a spare uart …

Please - not sure what you mean - are you saying if Uart1 or any other UART if SmartPort is selected must have it’s MSP also selected - I beg please, how does this come about and what are the consequences if the MSP is de-selected, the mind boggles…joe
