| Example of using secure telemetry over PPRZ protocol over UART | ||
|
|
||
| This file serves only as an example and should not be used in real applications, | ||
| because it only passes through all data (so it is equivalent to using plaintext data). | ||
|
|
||
| However, this example should make it easier for users to devise their own encryption scheme. | ||
