Hello, DJI! What happened with Inspire after one of latest firmwares?? After realized Phantom 4 your birds start motors with compass error, it's very good(phantom 3 not start with compass error). Inspire 2 previously also started too, but with new firmware it show me error message and cannot start! It is professional drone, i have brain for decision-making can i start here or not. On the top of buildings or indoor flying i need start with compass error, for filming! It's not "Spark" or another baby drone, return take off function to professional drones, it very strong problem in work.

Can you take off in ATTI mode? Sometimes magnetic interference may be too severe in particular place. Also without firm GPS lock the drone will not risk taking off.

Hi Necromant, there are some issues with the latest firmware. Please downgrade to V100 and wait until Q2 2019 for new  Inspire 2 firmware.

Yea sure: https://www.dji.com/uk/newsroom/ ... ttery-investigation
On the 2019-01-16 they posted this update on the whole TB50/55 situation.
They stated "After extensive testing and close performance monitoring, DJI has determined that the current firmware, issued in December, eliminates the need for another firmware update this month."

When you look at previous release windows for I2 firmware, it will be a few months until they will release a new one if you consider internal beta testing.
Especially since how many issues there are with v300 and batteries being killed for many users (with no fault of their own), you can imagine that DJI might want to try and get v400 right  this time around. Hence why I think it will come early Q2.

If your I2 will not start due of a compass error it has a reason for it.
A typical szenario would be on top of a building. Usualy there is a lot of iron in the concrete. There are also a lot of cables and other electromagnetic stuff.
If you initiate the I2 with such interference it can misslead the compass and set wrong start values. As soon as you fly up and leave the interference the compass would turn to its natural direction and tell the FC the drone is turning even it isn't. Together with different gps information this can lead to errors.
Those who fly since the early days remeber a lot of crashes because of initializing with electromagnetic interference.

There is always a solution.

- Try to move the starting point.
- Elevate the starting point on a aluminium, plastic, wooden  table or anything else non magnetic
- Learn on how to do safe hand starts and landings

On my last job I had the same known problem on top of a new 17 floor building. Changing the starting location did not help but hand starting while standing on top of alu aircon box was far away enough.
Plan B would have been to stay on top of the building, where the talent was acting, but starting the drone on the ground floor flying up to the top and landing it back at the ground floor.
There is always a work around ;)

Thank you, Captain!

I can fly in attitude mode, if i have problem with compass in air. Big trouble of this firmware - it is't start after compass error, after move to another location. It need restart or calibrate compass(it is stupid action - calibrate compass on building or in the room).

How much time DJI programmers need to resolve this problem? 1 Year or maybe 2 years?  1 line of program code!!!
