About the GPS reading

Hi, i am new in working with mangOH RED. I am testing the user guide and once i connect the SIM at first, it was showing the correct GPRMC reading. But suddenly, it shows empty. I did not get it, it is the problem with the SIM or configuration? Could someone help me in this issue?

Hi @shahahsanuzzamanmdta ,
Did you connect the GPS Antenna ? Sim configurations has got nothing to do with GPS data .
Please make sure you are connecting GPS antenna in the correct slot .

Hi @shahahsanuzzamanmdta ,

@shahahsanuzzamanmdta which module are you using ? what is the firmware version ? Did you try testing at different locations ?

@Akshaysk it is 7601G module and if i change the location then it works that means need to move after a while always? or need to change the gps cofig? the firmware is updated one.

Hi @shahahsanuzzamanmdta ,
Ideally you should be able to get the RMC values continuously if you have the fix .

I am trying to use AT commands to have the GPS readings. Could you please help me in this issue? How can i send AT commands as like arduino?

What is your application ? The module has a dedicated application processor , framework to do the job for you . why don’t you use the API’s from framework .

Thanks for your help. The application is to read GPS location and send SMS to a phone number.
