Re: UART ISR handler

Looking at what uart_driver_install does, you may need to call 'uart_module_enable' before doing anything else... it could be that your UART still is clockgated and as such doesn't do anything. I tried adding the UART module enable, still nothing on the output. We will finally roll back to the prev...

UART ISR handler

Hi, I'm trying to develop an ISR handler for UART communication (RX only). I can't use queues or FreeRTOS tasks so the example provided in the ESP IDF won't do the trick (although I have tested it and it works well). I also have seen here on this forum a lot of topics and messages discussing this co...

Hard resetting issue

Hi, My company works on several ESP32 based projects and we noticed an issue when using the ESP IDF scripts/tools to flash and reset the development kits. What is happening is that from time to time the device will not be reset when using a flash command and we cannot identify what could cause such ...

Re: WiFi and ADC1

This seems to be an issue on IDF v4.2.2. It works without issue on the github master branch.

WiFi and ADC1

Hello, I have an issue with the simultaneous usage of ADC1 and WiFi. The documentation states that ADC2 read will fail when using WiFi. However there doesn't seem to have anything wrong using ADC1. The issue I face is the same every time, when reading an ADC value, the WiFi will be disconnected (rea...

Re: Wi-Fi auto join on boot

Hi, In my case fast scan example gives the same result (~1 s to be connected to an AP) but 4 more to get an IP adress. As a I see in your logs, acquiring an IP is much faster than that, is there any way we can cut that time? (Maybe not possible since it is the DHCP client and must depends on the AP?...

Wi-Fi auto join on boot

Hello, I'm trying to find a way to automatically join a previously joined Wi-Fi access point after a reboot. As far as I know this feature should do the trick: https://docs.espressif.com/projects/esp-idf/en/v4.2.1/esp32/api-guides/wifi.html#wi-fi-nvs-flash I used the ESP IDF station example to join ...

Re: Using FatFs directly fails with a Guru Meditation Error

Yes thanks that was it ! I had to raise the main task stack size to get it to run. Also my path was wrong, I replaced "/sdcard/hello.txt" by "hello.txt". I will continue to adapt the POSIX example to find out if that works but is there anyway that my original issue could be related to a memory issue...
