Configure Ublox ANTARIS4 using pySerial in Raspberry Pi

Hello!

I am trying to get raw data in .ubx file using raspberry Pi and pyserial python module.

Below is my code that is working:

import serial gps = serial.Serial('/dev/ttyACM0') out = open('test.ubx','w+') try: while True: line = gps.readline()\`` out.write(line)\`` except KeyboardInterrupt: out.close() print "file closed" pass 

However the problem is that when I convert this generated ubx file using RTKCONV I only get obs file but not nav and any other file. I know that this is happening because SFRB (Subframe Data) messages are not enabled. However enabling this message in U-center is temporary (i.e. resides in volatile memory).

So, Either I need way to permanently enable the SFRB messages or

I need method to enable this message programmatically.

I got the hexadecimal code for this config message here. But I am unable to get any way to send this config message using python code. I tried using lines below before try statement in above code.

gps.write(b'!HEX b5 62 09 01 09 00 14 6c 00 00 00 00 00 00 ff 92 f7')

and

gps.write('!HEX b5 62 09 01 09 00 14 6c 00 00 00 00 00 00 ff 92 f7')

but no luck at all.

What am I missing here?

I am new to this whole thing.

Any help is appreciated. Thank You!

Assuming "1000V" is a peak voltage (plus and minus), that is 354 Vrms and into a 50 ohm load would be 2.5 kW.

Can I use SPRZ5043Z IC lna as tx or not? There is lna4all which can do tx and rx with some modifications.

Hello all,

As per my title I want to know that SPFZ5043Z can be used as tx lna too.

Comment on List of SDRSharp Plugins by Timothy Roberts

Tony, I don’t think any repo like areas have what you’re asking. I will tell you a couple things. You don’t need a plugin manager at all, and SDR# has evolved to where older plugins no longer work with newer release SDR# builds.
Look for Valisi’s plugin website. You may need to turn on Russian translate.
