Getting Started
Solution
Use TI-Connect to transfer the module to the calculator. The menus only
appear in the editor after the from tello import * line.
Transfer the TI_runtime file to the microbit card.
Quit the program. Unplug the cable from the calculator and press the reset
button on the back of the microbit card and the RST button Grove WiFi
module. Reconnect the cable to the calculator and try again.
The default TX and RX pins for the BitMaker expansion board are P2 and P1.
If using a different expansion board other than the MakerBit, you must
configure different TX and RX pins unique to that board's port. For example,
if using the Grove Shield, plug the Grove WiFi into the P1/P15 port and enter
Tello uses flight vision for positioning. A well-lighted space is required.
Additionally, the floor should not be uniform or glossy in appearance. Try
moving to an area with a different floor appearance with lots of light.
Bent propellers and interference with propeller guards may be the problem.
Replace propellers (notice markings on props and placement order). There is
also a IMU calibration that can be done using the phone software. See the
owner's manual.
Charge the drone battery.
The battery charge must be greater than 50%.
•
Check that the WiFi module is in the correct port.
•
Check that the expansion board's power switch is ON if present.
•
Check that all batteries are fully charged.
•
Check the external battery connected to the expansion board is turned
on.
•
Disconnect and reconnect the calculator and the external battery and try
the program again.
