Sending Assisted GNSS (A-GNSS) to Bangle 2 GPS (AT6558)

did you get some data from their servers?

Just tried it and I got.
I suspect we will have to raise a support case on the site to a trial username and password.
The code is from 2015, so maybe the trial account is no longer the same.

$ ./agps_demo 
AGPS demo.
Create a socket.
Get agps server by name.
Copy agps server information to socket address struct
Connect to agps server.
Build agps message.
Message: user=freetrial;pwd=123456;lat=30.1;lon=120.2;
Send message to agps server.
Wait for server transferring agps data.
Received 25 bytes from agps server.
All agps data are received.
Total bytes: 25
Demostrate agps_buffer, agps_buffer_length = 25.

ERROR: INVALID USER/PWD.


Now, you can send these data to gnss module through tty.
Using code like:
write(tty_fd, agps_buffer, agps_buffer_length);
