DJI Matrice 400 Update Brings Cleaning Mode And T Mode Enhancements

The latest firmware update for the DJI Matrice 400 introduces a series of practical upgrades designed to improve safety, control and operational efficiency. Released on 31 March 2026, firmware version v17.00.01.00 focuses on close range precision work, enhanced flight safeguards and improved data capabilities for enterprise users. For UK operators working across inspection, public safety and infrastructure projects, these changes bring meaningful improvements to day to day workflows.

Improved Precision With T Mode Enhancements

One of the standout updates is the refinement of T mode for close range operations. The aircraft now defaults to a slower and more controlled flight profile when switched into this mode, making it far better suited to detailed inspection tasks.

With a reduced minimum flight speed and a tighter obstacle avoidance threshold, pilots gain greater confidence when operating near structures. This is particularly valuable for asset inspections, confined environments and sensitive sites where precision is critical. The update helps reduce the risk of sudden movements while maintaining consistent positioning.

Cleaning Mode Supports Challenging Environments

A new Cleaning mode has been introduced to support operations in environments where sensors may be affected by dust, debris or moisture. When enabled, the aircraft prioritises millimetre wave radar for obstacle detection, allowing it to maintain safer flight performance in less than ideal conditions.

This is especially relevant for sectors such as construction, utilities and industrial inspection where airborne particles or surface contamination can impact sensor reliability. Operators are advised to maintain clean sensors for optimal positioning, but this mode provides an added layer of resilience when conditions are not perfect.

Enhanced Flight Safety With Battery Reserve Settings

Battery management has also been strengthened with the addition of a return to home reserve setting. This allows operators to define a minimum level of battery that must remain available for safe recovery of the aircraft.

For UK enterprise users operating under strict safety frameworks, this feature adds a valuable layer of control. It supports more predictable mission planning and reduces the likelihood of low power incidents. When Delivery mode is active, the system automatically increases the reserved power threshold to reflect the demands of that operation.

Expanded Capability With Delivery Mode Integration

Delivery mode can now be enabled through the PSDK interface, opening up new possibilities for developers and organisations building custom drone applications. This enhancement supports more advanced workflows, including automated transport tasks and integrated logistics solutions.

As drone adoption grows across sectors such as healthcare, infrastructure and emergency response, this level of flexibility allows organisations to tailor the Matrice 400 to specific operational needs.

Video Recording Now Meets MISB Standards

For operators working in defence, security and surveillance, the addition of MISB compliant video recording is a significant step forward. When paired with H30 series cameras, the Matrice 400 can now produce footage that aligns with recognised metadata and video standards.

This ensures compatibility with a wide range of professional systems and platforms, making it easier to share, analyse and store critical data. It also supports compliance with industry requirements where standardised video formats are essential.

Improved Connectivity & System Stability

The update also introduces guidance around 4G enhanced transmission data usage, helping operators better understand connectivity performance in the field. Reliable data transmission remains a key factor for remote operations, especially in large scale or complex environments.

In addition, a known issue affecting the BS100 battery station has been resolved. This fix improves overall system stability and reduces the risk of unexpected interruptions during charging cycles.

Why This Update Matters For UK Operators

For professional drone users in the UK, this firmware update delivers tangible benefits across safety, precision and operational flexibility. From improved close range handling to enhanced battery safeguards, each upgrade supports more reliable mission execution.

The addition of Cleaning mode and MISB compliant recording reflects a clear focus on real world use cases, ensuring the Matrice 400 continues to meet the evolving demands of enterprise applications.
