I'm running a small test network of 8 ESP32 devices on desk. ESP-IDF is release/v3.3 (branch), project is https://github.com/fieldtracks/JellingStone . The devices to BLE scannning + beaconing. Results are transfered over wifi / mqtt.
Every couple of minutes some devices loose their connectivity to the broker. Log:
Code: Select all
W (628325) TRANS_SSL: Poll timeout or error, errno=Bad file number, fd=59, timeout_ms=10000 E (628325) MQTT_CLIENT: Error write data or timeout, written len = 0 E (628325) MQTT_CLIENT: Error to public data to topic=JellingStone/b4:e6:2d:a9:42:df, qos=0
Do you know what's wrong here?
