Hello
I’m working on MC60 (openCPU). I have a question about EPO downloading and AGNSS.
as it mentioned in MC60 GNSS AGPS Application Note document, the module can automatically download and update EPO file.
Also I’ve tried ATcommands to get location using below commands:
AT+QIFGCNT=2 // Set PDP context
OK
AT+QICSGP=1,”CMNET”// Configure APN ( I used my apn)
OK
AT+CREG?;+CGREG? // Check network status
+CREG: 0,2
+CGREG: 0,2
OK
AT+CREG?;+CGREG? // Check network status
+CREG: 0,1
+CGREG: 0,1
OK
AT+QGNSSTS? // Read time synchronization status
+QGNSSTS: 1 // Time synchronization completed
OK
AT+QGNSSEPO=1 // Enable EPOTM function
OK
AT+QGNSSC=1 // Power ON GNSS
OK
AT+QGNSSRD?
.
but it seemed to be no difference between getting data using AGNSS or without using it.
Am I doing anything wrong? is there anything I am not doing about EPO files?
I’m using SDK v1.7 and programming based on epo_callback.
