hi ,
you can also refer to the ESP-NOW example in IDF:
https://github.com/espressif/esp-idf/bl ... ain.c#L187

Please refer to this info: If there is a lot of ESP-NOW data to send, call esp_now_send() to send less than or equal to 250 bytes of data once a time. Note that too short interval between sending two ESP-NOW data may lead to disorder of sending callback function. So, it is recommended that sending t...

sorry to reply so late.

Currently, the `esp_wifi_set_channel()` can be called in staion mode, please refer to the branch https://github.com/espressif/esp-idf/co ... 2440ed82ef

Hi kwijibo007,
The esp_wifi_set_channel() API has been updated in IDF master branch https://github.com/espressif/esp-idf/co ... 2440ed82ef.

hi benjavita, The default ESP-NOW bit data is 1Mbps. We are thinking about adding this to the ESP-NOW doc. As for the memory error, I have tested with the espnow example in IDF, and I have set the send delay time to 1ms in menuconfig, there is no memory error. Can you confirm that the memory error i...

@Javier
The default ESP-NOW bit rate is 1 Mbps. You can use the workaround as @WiFive mentioned, call `esp_wifi_internal_set_fix_rate()` to set the reasonable rate.

Hi kwijibo007, Is there a way to force "the slave" to listen on a particular channel without creating a softAP or connecting it to the same Wi-fi? In my testing (and searching) esp_wifi_set_channel() does not work on "the slave" without a SoftAP. Why is it that it doesn't work when "the master" is c...

Answering myself with what I found on google and tested. adding this esp_wifi_set_ps(WIFI_PS_NONE); solved my poor transfer quality in STA mode connected to my wifi. Switching to AP_STA also works. Yes, you are right. When ESP32 has connected to a router, you need to close the MODEM_SLEEP, otherwis...

hi Ritesh, I think detlier's description is pretty clear. What we said is the timer that the SoftAP found the STA has been out of range or power off. You can reproduce this issue by the following steps easily: (1) Use two ESP32 devices, one is as SoftAP, the other is as STA (2) STA connects to the S...

Sorry liuzhifu, I missed this. Thanks for the info. Do you know if it's hard-coded in the IDF or a dependency? I don't usually like messing around with dependencies, but if it becomes a hard requirement it would be good to know where it's set. Hi detlier， We know where it's set, and currently it's ...
