Not entirely sure what the specific issue with esp_timer is here, but I think you may be better off rewriting this to use a hardware timer that unblocks your own task... the reason is that all esp_timer callbacks are called from one single task, which means that if e.g. the WiFi driver schedules a ...

I am doing some serial communication (1200 baud) on a single GPIO (transmitting and receiving on the same line), and I am running into an issue with the GPIO ISR Handler and the ESP_Timer. I am using the esp_timer for the actual reading of data, and I am using the interrupt for detecting when data h...

Hello, I am using an ESP32-WROOM-32UE (16MB). Basically what I am doing is a serial transmit/receive function on a single GPIO to communicate with a sensor. I have 2 hardware timers running (1 for transmit function, 1 for receive function). I also set up some interrupts that are used for the receivi...

Hello, I am using an " ESP32-WROOM-32UE (16MB) ". I set up a hardware timer, and if I have the auto reload function enabled (e.g. "TIMER_AUTORELOAD_EN") everything works fine. If I disable the auto reload function (e.g. "TIMER_AUTORELOAD_DIS"), as soon as the timer is up, I get the error "-Guru Medi...

Thank you for the response. I tried your troubleshooting suggestion, and still could not make any progress. So I ended up ditching the OpenSSL local server, and hosted the binary file on the cloud instead (Azure Blob Storage). I can access this file from any computer/phone and it downloads just fine...

Hello, I was running through this example (simple_ota_example) and I am having some issues: https://github.com/espressif/esp-idf/tree/master/examples/system/ota I followed the steps exactly as it states. I can see my local IP address is 192.168.1.8, so I used that for the "Common Name" when creating...

Hey guys, I have been struggling to find a good example/tutorial on how to set up a cloud based OTA firmware update scheme. Everything I come across is where you push an OTA firmware update through the local network via local server. I want to be able to put the binaries in the cloud, have the ESP32...
