I have a quectel 5G module RM502Q-AE and the purpose is to obtain position with a GPS antenna
I fellowed this tutorial :
RM500Q-GL 5G HAT - Waveshare Wiki
And in the part of “step dial-up intenet access”, i did the AT command, but they didn’t work
I had error for these two.
So i wasn’t able to obtain the position, so i don’t know what to do.
Thanks for your help.
AT+QNETDEVCTL won’t work for RM502Q.
For RM502Q you can follow the
Quectel_RG50xQ&RM5xxQ_Series_AT+QCRMTOOL_Data_Call_Application_Note_V1.0.pdf (306.7 KB)
or use the quectel-CM to setup dacall.
Thanks for your answer, i will try it.
I have another problem if you can help me.
It concerns the GPS Positioning with the same Quectel module
I turn on the GPS : AT+QGPS=1 , it’s OK
But when i try to obtain the position with AT+QGPSLOC=0 , i have error 516 and i don’t know how to solve this issues, i tried the GPS antenna indoor and outdoor and always the same error
Thanks for your answer
Can you get the position through the nmea log?
If you set hte AT+QGPS=1 , the nmea log would output from the nmea port.
516 means “Not fixed now”.
It takes some time for the module get the location.
Yes, after enabling the GPS, i open the NMEA port, i have the NMEA frame but without information of Latitude, Longitude… etc
Like in the picture below. (And i have the same thing when i use linux).
Maybe it has something to do with the antenna.
The GPS gntenna is different from the LTE/WIFI/BT antenna, and it should be placed outdoor.
From the nmea log, the GPGGA didn’t tell us the position fix data , there is no enough active satelites from the GPGSA.
So how can i fix this and obtain the position please?
Could you show how the antenna is placed?
This is the antenna, i put it like this outdoor
(Ps: i also tried to put it in the other face and same thing)
How it connect with the RM502Q-AE？
btw，the antenna should put outdoor.
Hello, yes i put it outdoor and in a tuto from waveshare, i saw that i have to connect the GPS antenna to the interface of ANT3 of the module
Like shown in this picture
Yes. the GNSS antenna should connect with the ANT3_GNSSL1.
Yes, so the GNSS antenna port i used is the right one.
Then what am i doing wrong? Why it doesn’t work?
Again thanks a lot for your answers.
RM502Q-AE only support Passive Antenna.
Could you check whether it is passive antenna or active antenna.
Yes, it’s a passive antenna
I get this know, what do you think?
Please wait for several seconds. It might work and return the location for the GPGGA.
