Pico-LoRa-SX1262 - how to use AES encryption?

[qubit999]

I have Pico-LoRa-SX1262 and I was trying to do something like this:

uint8_t key[] = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
                 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F};
radio.setAESKey(key);
radio.enableAES();

Is there any way to transmit messages encrypted? Or do I need to implement myself encryption?

Where did you find those last two lines? 🤔
But RadioLib already has some AES functionality in the Crypto folder.

I successfully implemented AES using the Cryptography lib.

Those examples are for the RF69 radio, which has a built-in AES encryption functionality. SX1262 doesn't have that, you have to do it in software. RadioLib has a class that implements AES-128. See the LoRaWAN implementation for details on how to use it.

Thank you for mentioning. This is my next step. I'm struggling right now with this: #1385

I successfully implemented AES using your Cryptography lib.
