Found a usb-serial adapter and changed update rate to 5hz and Baud rate to 115200 in u-center for both gps modules and now both are working with stock firmware.

I will also look into it once I find some free time
Thank you for all the effort and I am happy it’s working for you now 
can I use this to check the BN-220 GPS module on my RX?
I get nothing when running it on the RX…
Thanks!
