THEMA:

Just noticed this: "Data Level : TTL or RS-232,Default TTL level" and also "To make it be RS232 output, you need to use one TTL to RS232 converter cable"

My guess is that U-Center needs to be used, I'll see when the modules get here. just ordered a few.

Hey Tero!
Thanks for getting in touch with this...

I tried several configurations of the ports in UCenter.

This is what it looks like:


I guess the serial communicatin should be ok with 9600 8N1?

So its all about the protocoll IN and OUT
This are the options:



Any Ideas?
More to config than just the ports?

Wild guess is that those could be correct. When GPS 2.0 is started it will sens some commands to NEO with UBX and then use NMEA to read GPS-values. Since I cannot test or verify the BN-220 before they arrive I really cannot say, sorry. My order is shipped but it might take some time.

Hello Kmpec
I just sent a PM

Hey kmpec, please try to turn TX/RX around between arduino and BN-220.

This would be the "normal" way to connect;
- GPS TX -> Ardu RX
- GPS RX -> Ardu TX

After reading the interwebs there seems to be quite a lot of BN-220's tha need to be connected like this:
- GPS TX -> Ardu TX
- GPS RX -> Ardu RX

Does not cost anything to test so please do that

Tested with a really small BN-220 GPS: www.rc-thoughts.com/2021/03/rct-gps-now-tested-with-bn-220-gps/
