@akihiro Hi Akihiro, sorry about the slower response! We have a few people out of the office this week. Let me have Sheila prep a return label for you. That sounds like it was a defective set, so we'll just replace that for you.

@ldostis We just released a 2.44 with this fix in it. Please update to the latest version, and let us know if you're still seeing this issue

@akihiro We want to take a look at that particular controller, BLE board, and battery pack. I will have someone reach out to replace all of those components. Thank you!

@akihiro We'll take a look!

@akihiro Could you send one more image of your controller? I am most interested in the wiring on the Smart Inventor board. There may also be a defect on another part of the board so pictures would be very helpful in diagnosing the issue!

@ldostis Thank you for bringing this to our attention! We will take a look right away. What version of the dashboard are you running?

@bmartin_ascte Also beware of areas in the school where there may be lots of interfering network signals. It might be why some areas are having better luck than others!

@bmartin_ascte For the pairing issues, try updating to the latest version of the CoDrone library. Go into PyCharm's package manager and select the CoDrone library. Specify the latest version (1.2.8) and install that one. For your COM port issue, I recommend opening the device manager and figuring out which port the drone is connected to. PyCharm might try and connect to other ports that the drone isn't connected to so you may need to specify that port in the pair function: drone.pair('1234', 'COM3').

Let me know if you have any questions!

@bmartin_ascte The drone ID needs to be in quotation marks. Take a look at my previous reply or at our documentation page for an example. I hope this helps!

Hi @bmartin_ascte ,

Thanks for your questions! For Python, you will only need the BLE board. Make sure the other 4-pin cable (UART cable) is disconnected from the SmartInventor board. Only your MicroUSB needs to be connected to the BLE board. You do not need AA batteries unless you are using the remote control to fly using the joysticks. In that case, the BLE needs to be reconnected with the SmartInventor board.

The first time you pair, you will need to use pair(drone.Nearest) with one drone and BLE board at a time. Once you have labeled the two, rerun the code again with just pair() and verify that the device can pair with that drone. Then, turn off that drone/board pair and repeat with the next pair. We recommend doing this on your own without the students. In class, instruct students to always use pair() without the Nearest parameter. You can also pair using the ID like this: pair("1234") if the student knows the ID of their drone. This will prevent pairing issues and students pairing to someone else's drone and undoing all of the work you did to pair them!

As for drone performance, always check for debris in the motors, calibrate, and charge the batteries. This will affect the reliability.

Once you make these changes, let me know if this helps!
