最后自己找到的问题之所在，倒腾了好久，发现wifi发射的Power值超出了要求的设定值，获取到默认值是100，而要求设定tx_power是在84以内。 最后通过esp_wifi_set_max_tx_power函数设定20，即5dBm的功率为发送频率，wifi就正常连接和通信，不知道这个是不是bug？ 在 https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/api-reference/network/esp_wifi.html#_CPPv425esp_wifi_set_max_tx_power6int8_t 中对esp...

Welp, I could confirm that the correct combination to make PCNT and gpio interrupt work simultaneously is: PCNT setup -> gpio config -> gpio interrupt handler

I have tried gpio_config > gpio_add_handler > pcnt setup as well as gpio_config > pcnt setup > gpio_add_handler. In either case,only pcnt works. the interrupt handler won't be called. Without pcnt the interrupt worked

Hi, I am implementing a pulse counter for an encoder. I would also like to capture the edge in ISR and perform some action. However, when both PCNT and interrupt using `gpio_isr_handler_add`, the interrupt handler no longer gets called. I assume this was because the signal was routed to PCNT periphe...

Hello all, I designed a prodcut with ESP32S3NxR2 and the firmware was set to using quad PSRAM lines. However, due to stock issue a recent batch was assembled with ESP32S3NxR8. While I was told the R8 version is compatible with R2 in quad mode, it turned out to be not true and I was getting E (323) q...

I succeed implementing the asynchronous response using the following code Note the commented code, where I assumed that httpd_queue_work is used to delegate the http communication to the http server thread. However, without using httpd_queue_work it works just fine. This makes me wonder more when h...

Hi, I am looking at the http server component and found this function: httpd_queue_work. After tracing the source code, I found that It merely ask the http server thread to invoke the work callback immediately. The callback is not called in a standalone thread. I wonder what is the purpose of using ...

I think this approach with the "magic" size value would result in less readable code of the application. You could probably add a function-like macro to "hide" this detail, and make the calling code look nicer, but then it's not going to be any different to introducing a new API. Also, would it be ...

Hi wuyuanyi, What you describe should be possible. We could introduce something like esp_event_post_moved which would take ownership of the pointer and would accept the deletion callback argument instead of event_data_size. Internally the deletion callback (finalizer) could be stored in an esp_even...
