I need help connecting/enabling state NTRIP corrections (Alabama DOT) on FPX-T

I am looking for assistance in connecting my FPX-T, in Rover Mode, to my Alabama DOT credentials. I am receiving data on my GNSS, I have it set to rover, and I created my NTRIP client in SW Maps. I believe my account works since when I created the NTRIP client, it finds the list of mount points and saves. I have tried several mount points and I still get “Connection Failed!”, but no further explanation.

Thanks,

Boyd

@Jbankston , the Mountpoint Field will populate with the correct address and Port# only (without an active account).

Here’s a screenshot from SW Maps for my Alabama Account.

You will need to have the FPX outside and positioning effectively because the NTRIP Caster needs your location. If you are still having problems, it might be your account. Can you use your Creds to login at Spider Business Center - SBC Login ?

Thanks. That is helpful. My credentials work fine with SBC, but I am still getting a connection failed. There must be something wrong with my settings in my receiver. I created a couple of profiles in my receiver, but I am wondering if I need to do a factory reset and start over.

I would agree.
Seems like the only thing the FPX needs to do (for a successful NTRIP Connection specifically) is to send the GGA message.

I hate to ask this, but you are bluetooth connected to the FPX (and it is positioning) when you start the NTRIP connection, correct ?

I am connected by Bluetooth and it is positioning. I was getting about 19cm horizontal this morning over a short period of time. I tried enabling the factory reset and then resetting but it isn’t erasing the profiles. About the only thing it did was remove my WiFi settings. Is there way to reset directly from the GNSS?

Edited: I tried a third time to reset and at least the receiver said it factory reset so we’ll see how this goes from here.

I’m not familiar with all the magic that happens with a FPX-Tilt, in regards to the HW and RTK Everywhere.
The simple test would be to attempt the NTRIP connection with WiFi off (no WiFi Creds) and Tilt Mode OFF. The only comms would be SW Maps Bluetooth connection to the FPX-T.

Can you use a serial connection (even a Serial over Bluetooth App) to confirm GGA messages are being sent by the FPX, leaving SW Maps out of the equation at first?

And naturally, the ‘Send NMEA GGA to Caster’ slider must be ON in SW Maps NTRIP Client.

Ryan, I was looking at your screen shot and realized you sent that from an Apple device. I am using an android. I connected to my iPad instead of my phone and got an account error. So the first lesson learned was the account name was case sensitive. Once I resolved that error, I connected and was getting sub 6 cm accuracy with corrections. Thank you very much for your assistance! It still doesn’t work with my android yet, but I will investigate that later today.

Awesome! Glad you got it headed in the right direction at least :smiley:

I’d normally have a dozen Android tablets to test SW Maps and try to replicate your issue, but I’m not at home (for a few more weeks). It’s possible there is a snag with the SW Maps version you are using.
