Troubleshooting Wireless Connection

The wireless connection issue seems to be related to the softAP() function, which is used to create a soft access point (AP) on the ESP32-S3. The function appears to work when coded directly into the Arduino IDE, but doesn't work when compiling for Pixelix.

To troubleshoot this issue, let's take a closer look at the softAP() function and the board configuration.

softAP() Function

The softAP() function is used to create a soft AP on the ESP32-S3. It takes several parameters, including the SSID, password, and channel. Here's an excerpt from the function:

void softAP(const char *ssid, const char *password, uint8_t channel) {
  // ...
}

Board Configuration

The board configuration is stored in the board.ini file. The softAP() function is not explicitly mentioned in the file, but the build_flags section contains several flags related to wireless connectivity:

-D CONFIG_PIN_I2C_SDA=8U
-D CONFIG_PIN_I2C_SCL=9U
-D CONFIG_PIN_TEST=IoPin::NC
-D CONFIG_PIN_I2S_WS=10U
-D CONFIG_PIN_I2S_SC=12U
-D CONFIG_PIN_I2S_DI=13U
-D CONFIG_PIN_LED_MATRIX_OUT=16U
-D CONFIG_PIN_LDR_IN=6U
-D CONFIG_PIN_BATTERY_IN=IoPin::NC
-D CONFIG_PIN_BUZZER_OUT=IoPin::NC
-D CONFIG_SENSOR_LDR=SensorLdr::LDR_TYPE_GL5528
-D CONFIG_SENSOR_LDR_SERIES_RESISTANCE=1000.0F
-D CONFIG_BUTTON_CTRL=1
-D CONFIG_LED_TOPO=ColumnMajorAlternatingLayout
-D CONFIG_SUPPLY_CURRENT=3500U
-D CONFIG_RTC_DRV=RTC_TYPE_NONE
