How to get GPS data from EC200u-cn

IoT Modules LTE Standard Module
1

Hello Everyone,
I am working on EC200U-cn with STM32H503 nucleo board. With help of UART communication I have done basic HTTP(S) operations but now I am not unable to get GPS data maybe, I am doing something wrong so please correct me.

I thought the AT command synchronization is getting wrong, is there any way to make it right?
Following are the AT commands I have using to fetch GPS data
{“AT command”, delay}
{“AT+QGPSEND”,1000}, // First end any existing GPS session
{“AT+QGPS=1,30,5,0,1”,20000}, // Start GPS with parameters
{“AT+QGPSLOC=1”,20000}, // Get location in NMEA format
{“AT+QHTTPURL=85,60”, 1000},
{“placeholder_for_url”, 1000}, //dynamic URL
{“AT+QHTTPPOST=1,60,60”, 100}, // POST request
{“*”, 1000} //POST Data

Note: I have already checked the GPS on putty it is working fine there but when I trying to implement on STM32 it shows issue of “No valid data”.

Thanks;

Please send the AT command to power up the GNSS.

Hi,

I have a same problem too. I can’t to get location from EC200U. I have active antenna , Used preferred power supply and circuit also and i was waited more than 15 min in a open sky area But i can’t to get location data. Can you check anything i need to config or upgrade firmware.

Hardware part No: EC200UCNAA-NO5-SGNSA

Thanks,

Maybe you can try a passive antenna.

Hi,

I found the problem, After i change the Antenna connector it was worked and i got location.

For some module it only support passive antenna.

Hi Udhayakumar_mani,

can i get the At commands sequenece you have used as i won’t able to fix GPS also please tell me you are using active or passive antenna.

Hi @Tradewithbv,

I am using active GPS antenna.
