[hpsdr] Metis/Mercury Bandscope Data (EP=4)

[Phil Harman]

Hi Doug,

John Melton pointed  out this bug some time ago and I fixed it in a private release that I sent him.

I’ve just check the FPGA code in Metis V2.6b and the code to select the wideband data is in place. 

So to  start  without wideband data the command is 

0x01 

and with is

0x03

I’ve just tested the code using KK and it appears to work as expected. 

Please let me know if you are still having a problem.

--------------------------------------------------------------------------------
I am trying to suppress Bandscope data from being sent from Metis/Mercury to the PC. The firmware versions are Metis 2.6b and Mercury 3.4. I started the system using the designated command as follows (in Objective-C on a MAC running OS X 10.9.2): 

- (Boolean)startStop:(int)command
{
unsigned char msg[64] ;



msg[0] = 0xef ;
msg[1] = 0xfe ;
msg[2] = 0x04 ;
msg[3] = command ;
memset( msg+4, 0, 60 ) ;
        [ self write:msg length:64 ] ;
        return YES;
}

where the "command" parameter is set to 0x1. 

This is as per "Metis - How it works_V1.27" shown below:
  Start Command 

  Metis will start sending UDP/IP data to the ‘from port’, IP address and MAC address of a PC that sends a Start Command. The Start Command is a UDP/IP frame sent to the Ethernet address assigned to the Metis card and port 1024. The command has the following format: 

  <0xEFFE><0x04><Command>< 60 bytes of 0x00> 

  where

  Command = 1 byte (bit [0] set starts I&Q + Mic data and bit [1] set starts the wide bandscope data) 

Unfortunately, it seems to ignore the command and send both I/Q data (endpoint 6) and Bandscope data (endpoint 4). Otherwise everything works as expected.

Is this a known bug? Is there a workaround?
