Using UART2 on pin GPIO19 and pin GPIO21

[nicola]

Hi to everyone,
I have not an esp32 board available to make a loopback test (short circuit) between UART TX and RX and test it.
I want to allocate UART2 , changing default TX and RX, in order to talk with a GPS module .
Will this configuration work in your opinion ?

UART2 TX : IO19
UART RX: IO21

Hope you can help.
Thanks a lot.
Nico
