Why don't you use PORT 2 only? You can use it to power BT adapter and also receive RTCM stream.
I use this solution all the time.
Naturally, Port 2 is an option. But then you are limited to only fixing your position at your GPS unit. If you want a positional fix displayed on your phone so you don't need to be standing next to your GPS (a single Parani SD1000 will send a bluetooth signal to my phone from around 90m away) or if you want to fix your position at one GPS and broadcast it's base position to a rover via the bluetooth module then you'll need to able to export the NMEA signal from the base unit. This requires a second port, because the GPS500 won't send and receive signals via the same port. But again, what you've suggested is certainly possible.
Inspired from your tutorial i build my low cost NTRIP Box for my Leica SR530 that uses power from Receiver and has its own short range bluetooth for my Smartphone. With the additional 9 Pin D-Sub Connector you can also stream NMEA data from SR530 over bluetooth to the smartphone.
I used this Parts:
5V Mini Usb RS232 Bluetooth Serial Adapter Master-Slave ~9$?ÿ?ÿ runs with 5 volt, with two-way bluetooth communication
3A DC-DC STEP DOWN BUCK CONVERTER 8-22V TO 1-15V?ÿ?ÿ ~14$
case with cap ~2$
maye one of these or you got some jst connector with pin distance from 1.0 mm to 1.5mm, dont know excatly
JST 1.25mm 2-Pin Micro Female ~3$ ?ÿ?ÿ
Lemo Connector to connect to GPS500 like written May 16, 2017 6:21 am from Micheal D'Aubyn.
Maybe cutting some existing Lemo cable with 5 pin (FGG.1B.305) or 8-pin (FGA.1B.308).?ÿ?ÿ ~30$
Heat Shrink Wire ~6$
Soldering gun.
The chinese bluetooth module needs 5 volt so i need the step down converter to convert the 12V from the receiver (red + black cable).
Also the RX TX connector at the bluetooth module did not work correct, so i had to solder directly to Pin 2 and 3 at the 9-pin connector (thin yellow + white cable).
Like written here the bluetooth module is also equipped to charge over mini usb, when used with 3.7V 1400 mAh Li-Po battery, but i did not use:

I used the battery connector with JST 1.0mm (little to small) to supply with 5 volt from step down converter (yellow+ black cable). Maybe could have used VDD and GND soldering connector for 5 volt input but i choose this way.
Some cutting / drilling / soldering later it was finished and ready to connect to the NTRIP client app from Lance Lefebure (version 2018.01.14). Big thanks to Lance!
Thanks to Micheal D'Aubyn for inspiration and maybe this will help someone.

Micheal (and all members) Happy new year 2020.
I'm trying to use Lefefubure NTRIP with a GX1230 + GNSS, Android 9 smartphone and an RS232 bluetooth key. I intend to use port 2 as RS232, 115200, 8, N, 1. The connection between Android and BT is tested. I think the 1200 series is able to use RS232 bidirectionally, so I would prefer that the CGGA signal be sent to Android from the GX1230 from the same port.
What leaves me confused are the countless parameters provided in creating the configuration in the 1200 system.
I specify that I intend to manage the RTK through the intenal software (Smartworks and RX1210).
Are you or anyone else on the forum able to help me out?
Thanks and again, best wishes.
