They correspond to the two interrupt sources alternatively.

Hi again, I have some more information, It seems that the interrupt call arises in the time from when I configure and start the interface until i get the SYSTEM_EVENT_STA_START. I (4324) wifi: Init ampdu: 1 I (4325) wifi: mode : sta (24:0a:c4:03:68:80) D (4331) main_task(main_handler_esp_system_msgs...

Hi again,
yes I do ,10K pull ups, and I have verified with the oscilloscope that the level is not varying...

Hi again, as expected, solving my gaffe has brought back my former problem. I have two tact switches in my board used to start some functionalities. This is more or less my code: void IRAM_ATTR gpio_btn_isr_handler(void* arg){ uint8_t pio = (uint8_t)((int)arg); portBASE_TYPE high_priority_task_awoke...

You are right, I noticed it immediately when I saw the backtrace.
All comes from some other strange phenomenon I had, where a first spurious interrupt was called after boot. Like in the backtrace, the interrupt shouldn't been triggered. I will try to figure out what is happening...
Thank you

First of all thank you for your reply, it helped a lot. I've got this from the backtrace: 0x40009203 ?? ??:0 0x4008be31 rfcal_txiq ??:? 0x4008195c _lock_try_acquire /home/ibl/esp32/esp-idf/components/newlib/./locks.c:165 0x400d7c09 _vfprintf_r /Users/ivan/e/newlib_xtensa-2.2.0-bin/newlib_xtensa-2.2....

HI, I've been facing some problems with the NVS recently. I've been trying to implementa a Flash log to save some required events. Somehow I have reached a point where the NVS partition was full so the app was stucked and somehow nvs partition end corrupted. So, I erased the full flash. From then, I...

Thanks Angus for your answer.

Hi all, I'm facing some issues with UART2 while trying to communicate using a 2 stop bit length configuration. I've mapped UART2 signals to IO16 (Rx) and IO17 (Tx) and I'm using no flowcontrol. While checking my UART2 communication shortcutting Rx and Tx signals, I've noticed that my ESP32 does not ...

HI, I'm trying to connect ESP-32 to an AP through BPC . This is the code I'm using: esp_wifi_set_mode(WIFI_MODE_STA) esp_wifi_wps_enable(WPS_TYPE_PBC) esp_wifi_start() esp_wifi_wps_start(10000) And I'm not getting any of the events I expected to have: SYSTEM_EVENT_STA_WPS_ER_SUCCESS SYSTEM_EVENT_STA...
