def gnuradio::packet_utils::conv_1_0_string_to_packed_binary_string

(

s

)

'10101111' -> ('', False)

Basically the inverse of conv_packed_binary_string_to_1_0_string, but also returns a flag indicating if we had to pad with leading zeros to get to a multiple of 8.

def gnuradio::packet_utils::make_header	(		payload_len,
			whitener_offset = 0
	)

def gnuradio::packet_utils::make_packet	(		payload,
			samples_per_symbol,
			bits_per_symbol,
			access_code = default_access_code,
			pad_for_usrp = True,
			whitener_offset = 0,
			whitening = True
	)

Build a packet, given access code, payload, and whitener offset.

Parameters:

	payload,:	packet payload, len [0, 4096]
	samples_per_symbol,:	samples per symbol (needed for padding calculation) samples_per_symbol: int
	bits_per_symbol,:	(needed for padding calculation) bits_per_symbol: int
	access_code,:	string of ascii 0's and 1's
	whitener_offset	offset into whitener string to use [0-16)

Packet will have access code at the beginning, followed by length, payload and finally CRC-32.

def gnuradio::packet_utils::unmake_packet	(		whitened_payload_with_crc,
			whitener_offset = 0,
			dewhitening = True
	)

Return (ok, payload).

Parameters:

whitened_payload_with_crc,:

string
