RE: There's a problem encrypting the sensor values.

Hello,

If I recall correctly, the plaintext has to be the same number of bytes or more as the size of the block chiper (16 bytes if you use 128 bit AES key, or 32if you use 256-bit). Can you try to append '0' padding to your sensor data and see if it works then?

e.g.,

uint8_t sensor_data_w_padding[32];

memset(sensor_data_w_padding, 0, sizeof(sensor_data_w_padding));

memcpy(sensor_data_w_padding, sensor data, <len of sensor data in bytes));
