ISSUE with xEventGroupWaitBits

Hi Guys, I'm having a heck of a problem with the "xEventGroupWaitBits(wifi_event_group, CONNECTED_BIT, false, true, portMAX_DELAY);" everything works fine if I call this function in the main loop, but if I call it from another RTOS task it crashes every time: /esp-idf/components/freertos/./event_gro...

Re: how to check if internet is available

Thanks Kolban for highlight "IP_LOST_TIMER_INTERVAL" parameter. I will check it. When I state "internet is available" I means that ESP32 is connected to a local access point which is connected to external internet. As you wrote I'm looking for a way to discover if the modem cable has been disconnec...

Re: Sync with NTP and trigger an interrupt every second the clock ticks

Dear ESP32 Guys and Girls, How would you accomplish the above mentioned Task? (Using ESP-IDF) I'm thinking of something similar: 1 Sync Time with NTP Service from a server and set the local clock in the ESP32 (this is well documented and working) 2 Read current usecond till next sec, register a Tim...

Re: Monitor Baud Bug

Hi, This should happen with any linux or at least any debian distro I don't think it's just for WSL. I'm already on the latest IDF release. I'm not writing to the console at all. It happens as soon as IDF opens. Bellow is the output: MONITOR --- idf_monitor on /dev/ttyS19 921600 --- --- Quit: Ctrl+]...

Monitor Baud Bug

Hi, I know the following bug has been fixed in the new IDF: https://github.com/espressif/esp-idf/issues/1136 However there is still another bug left. I'm using the WSL Ubuntu on Windows 10 and it has the creators update. The 'Make Monitor' Crashes if the monitor baudrate is anything other than 11520...

ESP32 PICO D4 & External Ram

I was just trying to decide whether I should use the PICO D4 in my design or the D0W. I read in the datasheet that the integrate SPI flash voltage is 3.3V and I was also aware that the ESP-PSRAM32 Uses 1.8V. Does this mean that I can never use External PSRAM with the PICO-D4?

Re: SNTP on a different port lwip Compilation Error

Hi, Thank you for replying. I believe that is not true, if I copy all the components, then instead of using the libraries from ESP-IDF It will use my project folder to compile all the libraries. That defeats the purpose of having this whole advanced build system. I want all the other libraries to up...
