Hi
i have hl8548.
I must use QT to manager AT command.
so:
I open a serial port with QT and I send AT command.
Some commands works but the values of altitude, longitude is zero.
Belowe example of my commands and example of answers.
MY COMMAND:
sendAtCommand(“AT”);
sendAtCommand(“ATI”);
sendAtCommand(“AT+GSV”);
sendAtCommand(“SET-CURRENT-TIME”);
sendAtCommand(“LOOP 5”);
sendAtCommand(“AT+CSQ”);
sendAtCommand(“WAIT=3”);
sendAtCommand(“LOOP-END”);
sendAtCommand(“AT+CIMI”);
sendAtCommand(“AT+GSN”);
sendAtCommand(“AT+CGPSINF=0”);
sendAtCommand(“AT+CGPSOUT=8”);
//sendAtCommand(“AT+GPSNMEA=0”);
sendAtCommand(“AT+GPSINIT=41”);
//sendAtCommand(“AT+GPSPVT=1,” + QString::number(rate) + “,0001”);
sendAtCommand(“AT+GPSPVT=1,1,FFFF”);
sendAtCommand(“AT+GPSSTART=1”);
