I start writing some TSIP C code to extract raw carrier phase data from an Trimble iQlassen receiver.
My code will be released under GPL for GNU/Linux, as soon as i have it running right.
I know, Trimble Copernicus is raw carrier phase capable too.
I am not sure if the enalbe raw data are disabled in iQlassen firmware.
As you have an Copernicus, i wonder if you have tested this feature.
Have you done this ?
thx very much,
PS: thx for share your breakout PCB.
I set 0x35 message byte3 bit0 to 1, enable raw.
i am talking and decoding several messages, all ok but no 0x55 raw data appears.

My iQLassen is working.
1- powered thru barel connector +5V center pin
2- NMEA use port 2 at 4800,N,8,1 pin2=Tx pin3=Rx
3- TSIP use port 1 at 9600,ODD,8,1 important ODD, pin2=Tx pin3=Rx
My problem now:
I am trying to get raw measurmentes ( carier phase,… )
I set ID=0x35 packet byte 3, bit0 to 1, enable raw. I sent (byte0=0x03,byte1=0x03,byte2=0x00,byte3=0x01),
the receiver should return 0x55 packet but it did not.
1- Does anyone has successfully get raw measurements from iQlassen or Copernicus ?
2- could the 0x35 be turned off ( firmware ) ?
PS: I am developping under GPL.

I have attached an iQlassen ( with a required piece of tape for isolation ) an 3v3 active antenna. The board powered from USB.
I am getting absolutly nothing from the receiver.
a) from a USB used to power on.
b) from COM1 with pin-pin and cross serial cable.
minicom under GNU/Linux
Trimble monitor under Windows XP
