All tasks on both cores hang/deadlock

I am building a gateway that will forward my car's CAN messages and messages from a GPS receiver to my iphone via WiFi. I have the Wifi code and TCP stack running on core 0. The code that processes the GPS and CAN messages are running one CORE 1. A "router function" forwards messages from CORE 1 to ...

Invoking espcoredump results in edit (via Visual Studio Code) of espcoredump.py file

I believe I have inadvertently modified my build environment such that when I invoke espcoredump.py I am placed in Visual Studio editor where I am editing the espcoredump.py file. I removed a version of Python from the Windows 10 machine on which I am running the Expressif IDE. I have been unable to...

send() returns "no more processes" upon WiFi transmssion

I am getting a error "No more processes" upon sending (using the send() command) after my code runs for about an hour. My ESP32 board is forwarding my car's CAN messages and GPS receiver messages to my iPhone. All indications are that the send's are successfully executing (send() returns number of b...

Re: Wierd issues with resetting / crashing--schematic for fix??

I too found behavior like MatCat for a ESP32 board designed by another vendor.

Might anyone have a schematic for the fix that MatCat described?

Thanks.

ESP32 board appears to freeze/unfreeze when USB port disconnected/connected

Hi Not sure if this is a HW problem or not. I'll start here. My board (see here for schematic: https://copperhilltech.com/content/ESP32_CAN_rev_B.pdf) is acting as a CANbus/Wifi gateway. (I am using Espressif IDE for writing the C++ application code.) The gateway listens for CAN frames on its CANbu...

WiFi: Undefined reference to esp_netif_dhcps_stop

Hi I get the above error when linking my WiFi AP code. I believe it means that the executable for the above call is not present. For debugging purposes, if I change esp_netif_dhcps_stop() to esp_netif_dhcpc_stop(), the code compiles and runs, but I get a failure when I try to set the static IP addre...

I can't find gptimer.h in IDE framework

I like to use gptimer utilities but can't seem find a gptimer.h file in the hierarchy of Espressif folders. Am I missing something?

Thanks.

How to generate multiple executables from single project and other anomolies

Hi This question has been asked before but I can't seem to apply the answer in my case, and I am seeing other strange behavior in my project. I have both .h and .cpp files I'd like to share between executables. I currently have a main.cpp and main2.cpp, both with an app_main() defined and both being...
