setupWiFiManager() disables the config portal whenever /config.json exists
(a security measure to avoid exposing the config data + OTA page). But if the
saved WiFi credentials are lost while config.json remains -- e.g. the NVS
partition is erased ({"cmd":"erase"}, or corruption) -- the gateway can no
longer connect AND the portal is suppressed: autoConnect() fails immediately
and the failure path calls ESPRestart(3). The device then reboot-loops
forever, un-onboardable, its SoftAP flickering up ~1s per cycle.
Only suppress the portal when config.json exists AND saved STA credentials
are still present (WiFi.SSID() non-empty). With no credentials the portal
stays enabled, so the gateway raises a stable onboarding AP and can be
re-provisioned instead of reboot-looping. The original security intent is
preserved for provisioned gateways (which always have saved credentials).
Reproduced + verified on a Theengs Plug (esp32dev, min_spiffs): with NVS
erased and config.json present, the SoftAP is now stable and accepts
provisioning via the captive portal, rejoining the broker normally.

Products powered by OpenMQTTGateway
Theengs Bridge, Bluetooth gateway (BLE) with external antenna
Theengs bridge is a powerfull BLE to MQTT gateway for over 100 sensors. Equipped with an Ethernet port, and external antenna, ensuring an enhanced range for your BLE sensors. It supports also WiFi connectivity.
Theengs Plug, Bluetooth gateway (BLE) gateway and Smart Plug
Theengs plug brings the following features:
- BLE to MQTT gateway, tens of Bluetooth devices supported thanks to Theengs Decoder library. The plug uses an ESP32 acting as a BLE to Wifi gateway to scan, decode and forward the data of the nearby sensors,
- Smart plug that can be controlled remotely,
- Energy consumption monitoring,
- Device tracker,
- Presence detection (beta),
- Local connectivity first.
Support the project by purchasing the Theengs bridge or the Theengs plug
