Say Y here to compile support for HCI BCSP protocol.
config BT_HCIUART_BCSP_TXCRC
bool "Transmit CRC with every BCSP packet"
depends on BT_HCIUART_BCSP
help
If you say Y here, a 16-bit CRC checksum will be transmitted along with
every BCSP (BlueCore Serial Protocol) packet sent to the Bluetooth chip.
This increases reliability, but slightly reduces efficiency.
