at+location = 2 in a9g

at+location=2

1. SDK version（SDK 版本）

{

}

2. In what kind of operation problems appear, and how to reproduce the problem ?（什么样的操作步骤问题会出现，是否是稳定复现，如何复现问题？）

{
Sometimes in the same place, after turning off and on the board a9g the GPS, they connect quickly, sometimes the GPS takes a long time to connect, and sometimes it does not connect at all. Is there a way to fix this in the code? Thanks.

This is part of the code:

`#include <SoftwareSerial.h>

SoftwareSerial mySerial(16, 17);

#define DEBUG true

String check_gps;
String check_coordinates;
String check_att;
String check_att_dos;
String check_conn;
String check_pdp;

int count_gps = 0;
int count_coordinates = 0;
int value_boton = 0;
int flag = 0;

String coordinates, lat, lng;
String mac = "a9g";

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
mySerial.begin(9600);
pinMode(4, INPUT);
//sendData("AT+RST=2", 1000, DEBUG); // per posar el mòdul en consum baix
check_gps = sendData("AT+GPS=1", 1000, DEBUG);
//sendData("AT+GPSRD=20", 1000, DEBUG);
}

void loop() {
// put your main code here, to run repeatedly:
if (check_gps.indexOf("OK") != -1)
{
count_gps = 1;
Serial.println("GPS connectat");
}
else
{
Serial.println("Intentant connectar-se");
check_gps = sendData("AT+GPS=1", 1000, DEBUG);
}
if (count_gps == 1)
{
if (count_coordinates == 0)
{
coordinates = sendData("AT+LOCATION=2", 2000, DEBUG);
Serial.print("at + location: ");
Serial.println(coordinates);
if(coordinates.indexOf("OK") != -1)`

I will try outside. I'm close to the window but perhaps I need to be outside. Thanks

[carlestecno]

I think the problem was to be inside and not outside

Gps are not working in building or inside room,
According to the wiki :
"GPS signals are unable to pass through dense materials such as concrete, heavy wood or steel cladding. To get the best effects from GPS tech, you really need visibility of a large area of sky to ensure that the received signal is strong enough pinpoint your location with any degree of accuracy"

A9G gps Test in outdoor:
log output
GPS fix mode:3, BDS fix mode:3, fix quality:1, satellites tracked:5, gps sates total:12, is fixed:3D fix, coordinate:WGS84, Latitude:1.855602, Longitude:9.190800, unit:degree,altitude:0.000000

You Can See : Satellites tracked is 5 (outdoor test)
Satellites tracked is 0 (indoor test)
