Freematics Forum

Hi

I am wondering if anyone have experience getting GPS data from the SIM7600 (or SIM5360)?

I am trying to make some code based on sim7600test and traccar_client_sim5360. They both have an initGPS


(tried to insert a code block here but tho forum keeps flipping out about " to few characters")


.... but it seems to get stuck in the second for-loop forever. I have tried to add AT+CVAUXV and AT+CVAUXS to set voltage to the external antenna (?) but to no avail. I have also added some text prompts to indicate what response-buffer responds to what code, and my code now looks like this:


(again, really not easy to try to post detailed questions to this forum )

Basically the gps reply is forever an empty dataset.


Appreciate any input on how to precede.

I have had the same issue.
Spent two days on it now and getting very frustrated.
I think it needs a signal from the Co-processor to turn something on.
Tried setting pin 15 high got that from here #define PIN_GPS_POWER 15 in the library
Tried setting pin 12 high found that soemwhere in the library as well
Tried initialising OBD still doesn't make any difference.

all i get is

Stanley are you able to offer any advice ?
I have confirmed its turned on
as I receive AT+CGPS=1,1
OK
and like your self set AT+CVAUXV=61 and AT+CVAUXS=1 the same as in the library's (which AT+CVAUXV=61 incidentally is wrong and fails anyway )
but if i load telelogger sketch it works fine.

Worked it out my wrong the GPS is a separate chip
Maybe should read a bit better!!!
