Hello.
I’m trying to develop GPS app, but have some troubles. MC60 do not response on AT+QGNSSRD?.
Version of firmware is A13.
I tried to reflash firmware, but had an error on gps state.
What can be wrong?

Hi,
I’m sorry to reply you so late.
Did you excute AT+QGNSSC=1 to power on the GNSS?
Hi,
make sure your module is in all-in-one solution mode.
please refer below image.
Also execute the AT+QGNSSC=1 to power on the GNSS.
Hello sir,
According to the example provided in SDK for example_gps.c, I compile it and reflash my MC60E module.
As shown in the example, all are callback functions and it should print all debug messages on the main port, but only "-- Ril is initialized "message coming on the serial port and nothing appear after that.
According to the user manual for GNSS engine, i have short J106 and also short GNSS_UART with AUX_UART to get data. but it not working.
According to the user manual D102 led should lit up but it’s not working.
To cross verify I also connect UART3 to PC but nothing appears on the screen.
What could be the problem?
Thank you.
Hi Nayan ,
Are you using EVB or your OWN board ?
We need to make GNSS_VCC supplied to make GNSS ON .
Thank you
Ratan
I have an EVB kit.
As shown in the pic I have short auxiliary pins and GNSS pins through a 1k resistor, still not working.
Whenever I power the GPS engine send data on the UART3 port, but according to example_gps.c I register UART1 for the reception for GPS data then it should dump data to the main port. But it’s not happening.
What could be the problem?
Hi ,
you need not to short that using Resistor , you just need to put both switch in ON condition .
For GPS to make On with example_gps.c , you need to give one command from main port .
See below , I sent “GPSOpen” and "GPSRead=“ALL” from main port .
Off course you can modify code to make these things automatic .

Hello Sir,
I have an MC60E EVB kit and I’m looking for an OpenCPU example to communicate with AWS.
I already gone through a topic which is raised by a person on this forum the link is
He is using an external MCU to communicate with MC60E chip. I also did same procedure by qcom software and i successfully able to send and recive messages from AWS. and vice versa
Now I am looking for a Example code in OpenCPU SDK to communicate with AWS.
If there any code available to communicate with AWS using MC60E OpenCPU SDK, please do share it with me.
Thank you.
