Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1567

Basic Infos

Hardware

WiFimanager Branch/Release: Master (Installed via Arduino Library Manager)

Esp32: ESP32-WROOM-32E

Hardware: DFRobot Firebeetle 2 ( https://wiki.dfrobot.com/FireBeetle_Board_ESP32_E_SKU_DFR0654 )

Description

I'm unable to compile any of the WiFiManager example sketches. Even a blank sketch as below will fail to compile because 'esp_wifi_set_country_code' is not declared. I'm not sure why that would be missing from DFRobot's library (assuming that's where it should be), but I'm new to Arduino/ESP development and I'm not sure what to do to work around/resolve the issue. I've also installed Espressif's board libraries using this URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json but it includes ESP32, ESP32-S2, ESP32-S3 and ESP32-C3 (mine is ESP32-E) so I don't know what to do. I assume DFRobot say to install their library for a reason too, so don't know if using one from Espressif could cause another problem? (I imagine pin constants will be incorrect - D1, D2 etc.). Any help would be appreciated.

Settings in IDE

IDE: Arduino IDE 2.0.3
Board Manager URL: http://download.dfrobot.top/FireBeetle/package_DFRobot_index.json
Board Selected: FireBeetle ESP32-E

Additional libraries: None

Sketch

#include <WiFiManager.h>

void setup() {

}

void loop() {

}
