BLE CRC interrupt

[DaCh_1995281]

Is it possible to get an interrupt when a BLE CRC check fails and if so, is it possible to stop a GATT write without response or GATT notification?

Hi,

We assume that you are mentioning about the CRC bytes that comes with every packet of data. In that case, the link layer will take care of the error and it will NACK the peer so that the transaction will happen again. There will not be any event/interrupt triggered towards the host side and it is not required. All this is taken care in hardware.

Please let us know if you are specifically talking about any API and how to handle the errors regarding that API.

Thanks
