Buffer length

-> EitherT String IO (Producer (Vector CUChar) IO ())

Either a string describing the error that occurred or the Producer

Returns a producer that streams data from a Realtek RTL2832U based device. You probably want to use interleavedIQUnsigned256ToFloat to turn it into a list of complex Floats. This function initializes and configures the device for you. Use sdrStreamFromDevice if you need more control over how the device is configured or want to configure it yourself.

-> IO (Producer (Vector CUChar) IO ())

The producer

Returns a producer that streams data from a Realtek RTL2832U based device. You probably want to use interleavedIQUnsigned256ToFloat to turn it into a list of complex Floats. This function takes a pre-configured device handle to stream from.
