# Firmware Release | F011V1R6

## Release Information:

### Bug Fixed

- Improved handling of MQTT broker disconnection, with automatic recovery of the
  publishing session.

### New Features

- Secondary (redundant) MQTT broker support, publishing to the redundant broker if the
  primary becomes unreachable, or to both brokers simultaneously.
  TLS supports CA certificate for both the primary and secondary brokers.
- Separate sensor data stream, published independently of the BLE scan data with its own
  sensor data posting rate and sensor topic.
- Access Point (AP) mode. The gateway broadcasts its own Wi-Fi network, so it can be
  configured directly from a laptop or phone with no router or cable.
- Static IP configuration from the web interface, to support intranet-based architecture.
- Factory Defaults button on the Telemetry and BLE pages, restoring that page only and
  leaving the network configuration untouched.

### Update

- Telemetry settings reorganized into three tabs: General, Primary Broker and Secondary
  Broker Settings.
- Web interface redesigned: revised navigation bar and page layout.
- Configuration guide updated to cover the above
