added stabilty in EnableGNSS function #27

Closed salmanfarisvp closed 4 years ago

salmanfarisvp commented 5 years ago

added current GNSS state AT Command's (AT+QGPS?) on EnableGNSS function, it gives more stability and reduces the not responding errors.

Hi @salmanfarisvp ,

My Wio LTE don't need retry. Could you tell me why it need retry logic? Can you get DEBUG log?

Thanks.

when I try get the GNSS data the Enable GNSS had some issues . 

## I/O Initialize.
### Power supply ON.
### Power supply GNSS.
### Turn on or reset.
### Enable GNSS.
### ERROR! ###
### Get GNSS location.

Oh...

Can you enable WIO_DEBUG macro and get log ?

Without the retry logic, it's doesn't fetch the coordinates.

Sorry too late reply. This behavior is by design. Please call GetGNSSLocation() repeatedly.
