In that case, the program must repeat the esp_now_add_peer call for every additional ESP-NOW client. Alternatively, the sender can prefix each message with a short identifier specific to one of the clients. The recipients then extract the prefix, compare it to their own, and ignore ...
To program ESP32 so it can communicate with an Android phone using the Bluetooth protocol, you have to set up the ESP32 Bluetooth serial library. For that, you must have an Arduino IDE setup with an ESP32 board installed. After setting the ESP32 Bluetooth, you have to install the Bluetoo...
If you don't already have the arduino IDE installed then go to thislinkto download it. The arduino software by default doesn't come with the board definitions for the various ESP32 boards. To get them to go thislinkand download the files in a zip. You need to unzip them to this loca...
ESP_ERROR_CHECK(esp_wifi_set_protocol(ESP_IF_WIFI_STA , WIFI_PROTOCOL_11AX)); just prior to the Code:Select all ESP_ERROR_CHECK(esp_wifi_start()); statement. The result was that the esp took a panic attack Not sure if its because I didn't use or place the esp_wifi_set_protocol...
