    Hi,

     

    Could you elaborate on what you want to do, or what you want to generate a checksum of?

    A generic CRC library is located in the SDK: \components\libraries\crc16 and \components\libraries\crc32

    Cheers,

    Håkon

    I am sending the BLE packet from the android phone and in order to ensure the correctness of the packet I need CRC at the nrf52832 side.So I want to know how to generate the CRC? Is there any tutorial for it? How does the CRC work for incoming packets?

    The Softdevice stack and the radio core automatically checks for CRC in the link-layer of the bluetooth protocol. This is already done for you when you receive your data.

    If you want to generate a generic checksum, please see the crc16 and crc32 libraries
