Using UART2 on pin GPIO19 and pin GPIO21
Posted: Tue Jun 23, 2020 10:57 am
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.
