Troublshooting ESP32-S3 WiFi AP
Posted: Tue Dec 05, 2023 7:45 pm
Having trouble getting a WiFi Access Point to work on a custom S3 board. Identical code on an ESP32-S3-DevKitC-1U works fine. Looking for any suggestions on ways to troubleshoot either hardware or software.
Development is PlatformIO running on top of Visual Studio Code for editing/building, then flashing using the "ESP32S3 FLASH DOWNLOAD TOOL V3.9.5" utility. For the dev kit I'm using the same source code as above but build/flash using the Arduino 1.8.19 IDE.
Code appears to run fine based on serial prints, but the AP never shows up for either my Windows or Ubuntu laptops. Same code on the dev kit shows up just fine.
- #include <Arduino.h>
- #include <WiFi.h>
- const char *ssid = "ESP32";
- const char *password = "PASSWORD";
- void setup() {
- Serial.begin(115200);
- Serial.println("Configure access piont");
- WiFi.softAP(ssid, password);
- IPAddress myIP = WiFi.softAPIP();
- Serial.print("AP-IP Address");
- Serial.println(myIP);
- }
- void loop() {
- }
Code appears to run fine based on serial prints, but the AP never shows up for either my Windows or Ubuntu laptops. Same code on the dev kit shows up just fine.
