@bbulkow A big thanks for bringing up this topic and finding a work around that at least alleviates the effects (if it doesn't completely solve it). Applying your work around at least in my case, and as far as I could witness so far, did the trick. Prior to finding this thread I already change the c...

Hi ESPers. About a year after the last message in this thread I happened to run into very that problem. Sorry to say, but the above mentioned solutions were not helpful. Updating the IDF or even playing with esp_http_client_config_t parameters such as buffer_size or user_data lead to no solution. I ...

@boarchuz Thanks a lot for the interesting reply. Using a wakeup stub is a brilliant idea that I didn't have on my radar. I will have to do more reading to understand how to elegantly swap between the different wakeup modes once I will call the ULP from the stub while sending the main cores back to ...

Dear ESP32ers. Currently I am working on a low power solution where a peripheral sensor sends a signal (good for an interrup) as soon as an event has occured. Then I can fetch and pre-process the data from the peripheral and based on the pre-processing result I want to either wake up the main cores ...

@boarchuz Thanks a lot for the example. It works like charme! Compiling your example without updating the IDF to the version uploaded by you lead to the compiler throwing complaints at me regarding the amended FSM instruction set. After over-installing your IDF it worked right away. And guess what: ...

HI ESP_Angus. Thanks for the swift reply. My feeling is there might be other obstacles even within the IDF that are currently in my way, and thus it could be tedious to seek by trial and error what could be the root cause. May be there is even a wrong library linked at some stage or something else. ...

Dear ESP32 S2 experts. Currently I am having trouble to get the ULP to run in the ESP32S2 (Saloa-Board). Apparently since the ULP has two modes (FSM as well as RISC-V) which can be utilized alternatively, further settings have to be done to get it off the ground. However despite following the steps ...
