Hello Adeel/ML, this is fine, thanks. Next doubt is the data format as input of the GMSK block. Should it be as sequence of unsigned char[] bits (01010101 ) or unsigned char[] bytes (\x55\x00)? Looking at the Mod code (gmsk.py), the modulator first does a bytes_to_syms(). Second, in

Hello list, I would like to transmit some data using gnu-radio. My data is a binary representation of an ASCII string. I wrote my own block that builds the frame (header, payload, CRC, trailer) as an array of 256 bytes (0s or 1s): gr_make_io_signature(0, 0, 0) gr_make_io_signature(1, 1,

1. Still I have to insert a Packer Encoder between my code and the GMSK mod? If yes, with which parameters? The GMSK mod is configured with Samples/Sym=50 , BT=0.4. No. U can make custom packet structure and in that case u need not to use Packet-Encoder. 2. Can someone explain me how to use the
