DJI Agras T100 Firmware v01.50.05.01 Adds Multi-Pass Boundary Sweeps

DJI has rolled out a fresh firmware build for the Agras T100, taking the agricultural flagship to aircraft firmware v01.50.05.01. Released on 15 May 2026, the update lands alongside remote controller firmware v02.31.40.46 and DJI Agras App v9.7.733, and it focuses on smoothing the spots that mattered most to operators in real-world use: obstacle handling on uneven terrain, boundary route control and Hill mode behaviour. If you run a T100 for spraying, spreading or lifting work, this is one to install before your next operation.

What's New In Firmware v01.50.05.01

The May 2026 release brings four headline changes:

• Optimised terrain-following obstacle avoidance for smoother flight in mixed-elevation fields.
• Added support for multiple boundary sweeps within boundary routes.
• Added support for prioritising horizontal bypassing towards the inside of the field during boundary routes in Hill mode.
• Added support for steering movement in M+ spreading mode (Japan only).

The full firmware bundle on this release is:

• Aircraft firmware: v01.50.05.01
• Remote controller firmware: v02.31.40.46
• DJI Agras App: v9.7.733
• DJI Assistant 2 for MG: v2.2.0

DJI notes that the bundle includes Intelligent Flight Battery firmware, so anyone running multiple TB100 batteries needs to update every pack — not just the ones in the aircraft when the update runs.

A Closer Look At The Key Improvements

Smoother Terrain-Following Obstacle Avoidance

The T100 already shipped with active phased-array radar and binocular vision for terrain following, but performance in steep, broken or canopy-dense fields had room to refine. The v01.50.05.01 build optimises how the aircraft balances altitude correction against obstacle reaction, which translates into fewer abrupt pitch or altitude changes when the terrain transitions sharply. For UK and EU operators flying mixed arable plots, orchards or vineyards on undulating ground, the practical benefit is fewer micro-pauses in the spray run and a more predictable feel under the sticks.

Multiple Boundary Sweeps In Boundary Routes

Previously, a boundary route walked the field's outer edge once. With the update, you can configure multiple boundary passes within the same boundary route. That matters for jobs where edge coverage is the weak point of the application — heavy-canopy crops, weed pressure along headlands or contact-active products that need overlap on the perimeter. Stacking two or three boundary passes inside one mission removes the need to plan and trigger separate edge missions.

Hill Mode Horizontal Bypassing

Hill mode is the T100's answer to slope work, keeping the airframe level relative to a sloped surface and adjusting spray height accordingly. The new build adds the option to prioritise horizontal bypassing of obstacles towards the inside of the field. In practice, that means the aircraft prefers to detour inwards (back into the planned route) rather than outwards over a boundary, hedge or drop-off — a safer default for hillside work where overshooting an obstacle could push the aircraft out of the working area.

M+ Spreading Steering (Japan Only)

A region-specific addition: M+ spreading mode now supports steering input. This is gated to Japan and reflects local operational requirements rather than a global feature change.

How To Update Your DJI Agras T100

DJI's recommended path for the T100 is to push the update via the DJI Agras App on your DJI RC Plus remote, with the aircraft connected and powered, and every battery in the working pool updated in turn. The release notes are explicit on two points: update both the aircraft and remote controller firmware to v01.50.05.01 / v02.31.40.46 so they remain compatible, and run the update across every Intelligent Flight Battery you operate. Treat this as part of your pre-season prep rather than a hot fix between fields.

A short checklist before you fly post-update:

• Confirm aircraft firmware shows v01.50.05.01 and remote shows v02.31.40.46.
• Update DJI Agras App to v9.7.733 on the remote.
• Cycle every TB100 battery through the update; the latest firmware travels with the aircraft, so a battery still on the previous build will trigger compatibility prompts.
• Run a calibration flight in a known area to confirm terrain-following and boundary behaviour against your usual benchmarks before pushing into production work.

Why This Update Matters For Your Operations

Firmware updates on agricultural drones rarely deliver headline-grabbing new hardware features, but the cumulative effect of releases like v01.50.05.01 is significant. Terrain-following refinements reduce missed and double-applied passes, which translates directly into chemical savings and more consistent application rates. Multiple boundary sweeps remove the planning overhead of stacking edge missions. And the Hill mode bypass change addresses a specific safety pinch point on slope work — the kind of refinement that adds up over a season of hectares flown.

For contractors and large estate operators, staying current also matters for warranty, support and DJI Care eligibility. Running last season's firmware into a busy spring is a false economy.

FAQs

Is firmware v01.50.05.01 compulsory?

DJI does not force the update, but the release notes warn that mismatched aircraft and remote controller firmware will affect operation. In practice, once you update one side of the pairing you should update the other, and you should keep app and firmware versions aligned across your whole fleet to avoid mixed-state issues.

Do I need to update every battery?

Yes. The release bundles Intelligent Flight Battery firmware, so every TB100 you operate needs to cycle through the update. Operating a freshly updated aircraft with an out-of-date battery will trigger compatibility prompts and may block takeoff.

Can I roll back to the previous firmware version?

DJI's note on the previous v01.31.09.06 release made clear that the firmware could not revert to an earlier version after that update. As a general rule on the Agras line, treat firmware updates as one-way — test on a non-production aircraft if you have a critical reason to stay on an older build.

Does the Japan-only M+ steering change affect UK or EU operators?

No. That feature is gated to the Japan region and does not change behaviour for UK or EU operators. Every other change in v01.50.05.01 applies globally.

Final Thoughts

v01.50.05.01 is a quiet but useful release for Agras T100 owners. It tightens the behaviour you rely on every flight — terrain following, boundary handling, slope work — without introducing anything that should change your operational SOPs. Pull the update before your next mission window, cycle the batteries, run a quick verification flight and carry on.
