Data buffer for radio data The radio can handle packets up to 127 bytes if CRC is disabled 125 bytes if using 16-bit CRC

◆ failureDetected

bool nrf_to_nrf::failureDetected

Not implemented due to SOC

Definition at line 366 of file nrf_to_nrf.h.

◆ outBuffer

uint8_t nrf_to_nrf::outBuffer[MAX_PACKET_SIZE+CCM_MIC_SIZE+CCM_START_SIZE]

The data buffer where encrypted data is placed. See the datasheet p115 for the CCM data structure

Definition at line 437 of file nrf_to_nrf.h.

◆ enableEncryption

bool nrf_to_nrf::enableEncryption

Enable use of the on-board AES CCM mode encryption

Cipher block chaining - message authentication code (CCM) mode is an authenticated encryption algorithm designed to provide both authentication and confidentiality during data transfer. CCM combines counter mode encryption and CBC-MAC authentication

Users need to take extra steps to prevent specific attacks, such as replay attacks, which can be prevented by transmitting a timestamp or counter value, and only accepting packets with a current timestamp/counter value, rejecting old data.

Encryption uses a 5-byte IV and 3-byte counter, the sizes of which can be configured in nrf_to_nrf.h Maximum: 8-byte IV, 4-byte counter, plus the MAC/MIC is 4-bytes

Examples: examples/RF24/GettingStartedEncryption/GettingStartedEncryption.ino, examples/RF24Mesh/RF24Mesh_ExampleEncryption/RF24Mesh_ExampleEncryption.ino, examples/RF24Mesh/RF24Mesh_Example_MasterEncryption/RF24Mesh_Example_MasterEncryption.ino, examples/RF24Network/helloworld_rxEncryption/helloworld_rxEncryption.ino, and examples/RF24Network/helloworld_txEncryption/helloworld_txEncryption.ino.
