Precautions to be exercised :
1) While uploading the code , the BT module must be disconnected from the Arduino , via removing the tx/rx wires , or the GND/VCC wires , so that the code is uploaded only in the Arduino , and no data is sent to the BT while uploading the code.
2) Waterproofing the structure is essential , so before putting in all the electronics inside the bottle , test for any leakages.
3) It is recommended to use fish wire in the first trial of the Boat due to multiple reasons :Low battery affects the BT module first
4) The specified range of the BT module is about 50fts without any Obstruction , but it is around 70ft or more in reality , so do not take the boat further than 40ft , because in a low battery situation , the first thing to be affected is the BT range and connectivity.
5) At Least 90% of the main Motor Propeller Should be inside Water for Straight Thrust & at least 60% of Wing Motor Propellers should be inside Water for better Controls.
6) If in case BT Disconnects(Continuous blinking) , ForceClose the app and restart it to connect again.
