Suggestion for parsing the result from sending the battery? command

[jsolderitsch]

I see that commands are sent with TelloCLI.write; e.g.

TelloCLI.write(command.c_str(), command.length());

If a packet returned contains an integer (for example from the battery? command) where would I add my logic in Arduino to parse this into an integer to make a decision: light an LED connected to the ESP32 if the battery is less than 20% for example.

Does the write command return the command result from the Tello? What Arduino data type is it so that I can convert it to make a logical comparison?

I am new to this sort of thing in Arduino.

Thanks.
