Description
The WiFi companion radio firmware (heltec_v4_companion_radio_wifi) calls WiFi.begin() once at startup with no reconnection handling. If the AP goes down or the device loses WiFi connectivity after the initial connection, it never reconnects.
Root Cause
The project uses espressif32@6.11.0 which ships with ESP32 Arduino core 2.x (ESP-IDF 4.4). In this version, the built-in WiFi.setAutoReconnect() is unreliable — it doesn't persist through certain disconnect reasons like AP reboots, beacon loss, or DHCP timeouts.
Expected Behavior
The device should periodically detect WiFi disconnection and attempt to reconnect automatically.
Fix
#2299
