It's been about a year since I posted this. Does anyone know of a working example in Windows?

printf("%.20s\n",(const char *)data); works. Thanks. It does insert occasional new lines that are not necessary:

Good idea. I changed it to 4096. This changed the behavior although it is erratic. Sometimes now it will print ~100 readings before crashing while other times it just crashes right away.

I am getting a stack overflow error when I try to display to the monitor ("make monitor") data received on UART 1 or 2. I am wondering if this is related to the the buffer sync problem (https://github.com/espressif/arduino-esp32/pull/1849) or is there something else I am missing? /* UART Echo Exampl...

Added asterisks.

Ok, didn't find a handy list anywhere so made my own: GPIO 0* 1 2* 3 4* 5* 6-11 are used by SPI flash exclusively 12* 13 14 15* 16 17 18 19 20 is not there 21 22 23 24 is not there 25 26 27 28-31 is not there 32 33 total GPIO: 22 pins GPI (input only) 34 35 36 37 not on WROOM 38 not on WROOM 39 Tota...

Ok, I think we have enough candidates now. Thanks everyone.

I found what I think is an older RFCOMM server example but the include file "rfcomm.h " is no longer in the latest IDF. #include <stdio.h> #include <unistd.h> #include <sys/socket.h> #include <bluetooth/bluetooth.h> #include <bluetooth/rfcomm.h> int main(int argc, char **argv) { struct sockaddr_rc l...

+1 also looking for RFCOMM example with some direction on how to connect in windows 10.

Already bought the book (see first post in this thread). It is helpful.
