2 COM ports in Windows when Bluetooth SPP connects

When I connect the ESP32 to my PC, I see 2 com ports in windows. I searched online for an answer. Found some examples but they showed two com ports as well. One of the ports (which one changes randomly) does not work. You have to try both. The 2 ports show up in windows device manager and at the com...

Re: Bluetooth classic SPP port to Windows COM port

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

Re: stack overflow while using multiple UARTs

Re: stack overflow while using multiple UARTs

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 (360) cpu_start: Starting scheduler on PRO CPU. I (0) cpu_start: Starting scheduler on APP CPU. UART test 1264 ...

stack overflow while using multiple UARTs

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...

Bluetooth RFCOMM example

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...
