Hello again! I was distracted by updating the esp-idf to version 5.1 and it was ... not easy) I checked heap size in the main_app cycle by using heap_caps_get_free_size(MALLOC_CAP_8BIT) and somewhere is leakage, heap decreases by about 2200+ bytes every cycle. And I know that it is in module with SD...

You was right! First problem solved! I rewrite part of code with pointers - add intermediate variable, into which I put the pointer and after this action check pointer. How it was: snprintf(msgString, sizeof(msgString), "%s", Data_currentRecordToJson(&msgIdx)); // собрали строку новых данных here ch...

Hi, I alredy read it, and I check pointer and in code and I checked it by logged ESP_LOGE(...). It was first what I've done. Then I found, that it can be stack overload (but adding +1kB to stack has no effect). I can't decode first error, where backtrace is with two addresses, but I decode second er...

Hello everyone! I use esp32-s3-mini-1 and SD card (one wire dat0). I have big programm with few tasks, and in main_app I write files to SD (every 2,5-3 sec, about 269-275 bytes)on maximum speed. And after some write cycles esp32 reboots with error. I have two cards and two devices and test all varia...

At first time it was like scheme (attached) and mounted 470pf_NM. After try to remove 470pf_NM -> better, but was data mistakes on 921600 baud rate and higher. Then both R on MCU_RXD =>1k. It stay stable on 921600, but form of signal is not very good ('0' level longer than '1' level, and rise front ...

If anyone is interested, I found a reason and problem was hardware. Esp32 (3.3V) connected to sim-module (1.8V) and level matching scheme (from sim-module datasheet) doesn't work with high baud rate. Sim-module understand all packets, esp32 doesn't understand packets. Actually with baud rate a littl...

Hello! I have problem with usins uart with standart baudratedifferent than 115200. When I use default 115200 and than check by uart_get_baudrate(UART_NUM_0, &brd);, brd = 115201 (small difference), but with 921600 -> uart_get_baudrate(UART_NUM_0, &brd);, brd = 922190 (huge difference). I undarstand,...
